EMS is an electromagnetic field simulation software which calculates fields (electric / magnetic / flux / potential / eddy currents), circuit parameters (inductance / capacitance / resistance / impedance / flux linkage), mechanical parameters (force / torque), and losses (eddy/core/hysteresis/ohmic). EMS is a Gold Certified Add-in to SOLIDWORKS® and an Add-in to Autodesk® Inventor® which enables you to simulate the most intricate electrical machines, motors, generators, sensors, transformers, high voltage apparatus, high power machines, electrical switches, valves, actuators, PCB’s, levitation machines, loudspeakers, permanent magnet machines, NDT equipment, inverters, converters, bus bars, inductors, bushings, or biomedical equipment.
Full 3D electromagnetic field simulation: EMS enables you to do both electric and magnetic simulations using your complete 3D geometry to ensure 100% accuracy and integrity of your designs. EMS also allows you to do both 2D planar and axis-symmetry simulations for designs where such simplification yields significantly reduced time for solution with no compromise on accuracy.
Seamless integration with CAD geometry: EMS seamless integration in the two main CAD platforms – SOLIDWORKS, and Autodesk® Inventor® empowers you to simulate the most intricate electromagnetic designs.

This paper proposes an analytical model that provides accurate self-inductance and mutual inductance calculations for two mutually coupled rectangular, planar and spiral coils with an air core which are equal and parallel, including the possibility of a lateral misalignment. Both single and double-layered coil geometries were modeled by considering an arbitrary number of turns with circular cross-section per layer.
EMS can be used as a transformer design software. EMS can be used to virtually study critical transformer design parameters, including:
A transformer shall not store any energy but rather transfer instantaneously from input to output. Unfortunately, in real life transformers do store some undesired energy. EMS computes the leakage inductance which represents the stored energy between windings regions occupied by non-magnetic media. Similarly, EMS calculates the mutual inductance which indicates the amount of undesired stored energy in the magnetic core and small air gaps.
EMS can calculate the maximum “hot spot” temperature rise at the core surface inside the windings center. This calculation is helpful in determining the smallest core size that meets the required power supply efficiency without exceeding the maximum “hot spot” temperature. To calculate the said temperature rise, EMS takes into consideration all transformer losses including, eddy loss, hysteresis loss, core loss, winding loss, and heat loss as well as the surrounding liquid temperature and convection properties.
EMS calculates the magnetic flux density and saturation levels in the core which can help in selecting the proper core material, shape, and size for any frequency and desired power output. The transformer’s designer ultimately aims at choosing a shape easy to manufacture, as small of a core size as possible, and the least expensive core material while respecting the required power without saturating the core.
Open and short circuit tests of a transformer are critical but costly and time consuming. EMS enables the designer to virtually run these tests accurately and efficiently.
EMS calculates the dielectric breakdown which is instrumental in selecting the proper bushings, surge arrestors and other insulating infrastructure. This type of calculation helps the designer meet the various insulation coordination standards.
EMS calculates the magnetic force acting both on the windings and the core material as well as the stress and structural displacement due to these forces. This type of calculations is helpful in guaranteeing the structural integrity of the transformer.
EMS can be used as a motor design software and can be used to virtually study critical electric motor design parameters, including:
Winding inductance and resistance play significant role in control and state estimation of electrical motors. The example of this would be phase current control in a SRM motor or rotor position estimation in a sensor-less BLDC. EMS can determine these parameter values for a desired set of frequency and current conditions.
EMS is full 3D modeling platform. This enables simulation of some important topologies and effects which are otherwise impossible to analyze:
-Skewing of slots or rotor poles is a common technique for cogging force reduction. Its results can be estimated only if interaction between stator and rotor is captured in all 3 dimensions.
-Advanced machine topologies such as axial flux and transverse flux machines inherently operate with 3D flux distribution and should be treated as such.
-End windings have a significant effect on the winding resistance, as well as its leakage inductance.
EMS can compute transient and steady state torque profiles for various electrical machine topologies such as Permanent magnet AC machine, BLDC, Switched Reluctance, Induction etc. Torque results for different rotor RPMs and winding currents determine the optimal operating conditions. Furthermore, EMS helps minimize the cogging torque by comparing its magnitude for different air gap lengths or fractional slot pitches.
Successful machine design depends on accurate representation of nonlinear phenomenon in the core material such as flux saturation, eddy current and hysteresis losses. EMS comes with a library of predefined solid and laminated core materials. Designer can easily compare different materials in terms of the saturation, core losses and overall efficiency. Core and winding loss results can be coupled with EMS's thermal solver and determine temperature rise and cooling requirements.
Machine radius, length and number of poles will greatly determine its torque and power rating. However, finer geometrical features of the magnetic circuit have profound effect on the machine performance. For example, shape of squirrel cage bars in an Induction motor will affect how torque changes with the rotor slip. All these parameters can be readily varied inside EMS to evaluate their effect on the performance of the motor.
EMS can be used as a parasitic RLC extractor. That is, it accurately calculates the resistance, the inductance, and the capacitance for any arbitrary 3D electric and electronics structure. These calculations take into consideration the proximity effect, the skin effect, the dielectric and ohmic loss, and the frequency dependence. In other words, both DC and AC parasitic RLC are calculated. These parasitic values are instrumental in modeling various electric and electronics devices and circuits, including:
RLC models for high-speed electronic devices such as ICs, PCBs, packages, and on-chip passive components are crucial in studying crosstalk and distortion, interconnect delays and ringing, and ground bounce.
RLC models are useful in simulating power electronic equipment such as bus bars, cables, inverters and converters commonly found in power distribution applications, and hybrid and electric vehicles.
The modeling of touchscreens found in today’s smart phones and computers heavily depends on the accurate calculation of the capacitance of the screen wires.
Electromagnetic fields and waves are widely used in the nondestructive testing technologies. Because EMS accurately calculates the magnetic flux and eddy current, it covers a wide varies of electromagnetic NDT techniques including: eddy-current testing (ECT), magnetic flux leakage (MFL), remote field testing (RFT), magnetic particle inspection (MPI), pulses eddy current (PEC), and the alternating current field measurement (ACFM). NDT screening commonly involves the movement of the NDT probes. EMS is well-suited to model this type of motion since EMS couples to Solidworks Motion.
EMS seamless integration in the three main CAD platforms empowers you to simulate the most intricate electrical machine, motor, generator, sensor, transformer, high voltage apparatus, high power machine, electrical switch, valve, actuator, PCB, levitation machine, loud speaker, permanent magnet machine, NDT equipment, inverter, converter, bus bar, inductor, bushings, or biomedical equipment. You don't need to "reinvent the wheel", just acquire a CAD model from the mechanical drafting personnel and start your magnet or magnetic simulation instantly without any modification. If you wish to make a modification on the acquired CAD model, you won’t need to go back to the drafting personnel because commercial CAD packages such as Solidworks are parametric and hierarchical. Change it yourself "on the fly". If the drafting department or colleague use a different CAD package, most probably they can save it for you in Parasolid, ACIS, IGES, STEP, STL, CATIA, or ProE kernel. You then import it into SOLIDWORKS®, Autodesk® Inventor®, or Ansys SpaceClaim and continue your electromagnetic design.
EMS is a true multi-physics software and simulation package. It enables you to couple your magnet, magnetic, and electrical design to Thermal, Structural, and Motion analyses on the same model and mesh in a hassle-free integrated environment without any need to import, export any data. This integrated multi-physics environment means: no cluttering, no jumping around, no mishmashing, no chaos, no confusion, and no mess. It also means: efficiency, accuracy, and productivity.
Your design involves electro-thermal aspects? Easy and hands-free! Just check "Couple to thermal" steady-state or transient in the study properties. EMS automatically computes the joule, eddy, and core losses and feeds them into the thermal solver. You may readily add non-electromagnetic heat loadings by applying volume heat, heat flux, or simply fixed temperature. Taking into account the environment conditions such as convection and radiation, EMS thermal steady-state or transient computes the temperature, temperature gradient, and heat flux and saves them to "Thermal Results" folder.
By the same token, the electro-mechanical coupling is also easy and hands-free. The "Couple to structural" option invokes the EMS structural solver, after transferring the local force distribution in relevant parts in addition to the mechanical loads and constraints, and then computes the displacements. The stress and strain are deduced subsequently and added to the "Structural Results" folder as well. If the more general electro-thermo-mechanical coupling is desired, EMS transfers both the thermal and structural loads to the Thermal and Structural solvers. The Thermal solver, in turn, feeds the thermal loads to the Structural solver which computes the final displacements that reflect both the electromagnetic and the thermal loads while taking into account the magnetic, electrical, thermal, and structural environments.
Electrical machines and drives usually encompass moving parts and components. Generally speaking, the resulting motion is simply rotational such as motors or translational such as linear actuators. Nevertheless, some applications such MagLev and Eddy current braking may provoke all the motion six degrees of freedom. In such case, only EMS can handle such intricate machines and equipment. Why? Because EMS couples to the most versatile and powerful mechanical motion package, Solidworks Motion®. To find out more about this robust package, please visit: https://www.solidworks.com/sw/products/simulation/motion-analysis.htm The coupling to SolidWorks Motion® is again hassle-free. After creating a SolidWorks Motion® study, simply instruct EMS to couple to it. That is it and that is all.
In recent years a burgeoning number of free 3D CAD models -millions- have become available in CAD depositories such as grabcad.com, www.3dcontentcentral.com, and www.traceparts.com. Consequently, you can simply grab a CAD model from the depositories, make necessary changes, and start your finite element analysis instantly.

Electrostatic is the branch of science that deals with the phenomena arising from stationary and/or slow-moving electric charges. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.e. the curl of the electric field is null. From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i.e. the derivative of the magnetic field with respect to time is also null. In other words, electrostatics does not require the absence of magnetic fields or electric currents. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly. In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored.

Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc(direct current). As it turns out magnetostatics is a good approximation even when the currents are not static as long as the currents do not alternate rapidly. Furthermore, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.
In EMS/ Magnetostatic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Ampère's law, i.e. the curl of the magnetic field is equal to the static electric current density, are invoked to compute the magnetic field and its related quantities due to electric currents and permanent magnets.

The Electrostatic module can help study a large number of devices and address numerous insulating and conducting phenomena. Below is just a partial list:
• Avoid rapid reduction in the resistance of an electrical insulator, that can lead to a spark jumping around or through the insulator, i.e. dielectric breakdown. This phenomenon is common in high voltage and high power applications.
• Avoid the ionization of a fluid surrounding a conductor, i.e. corona effect, in some applications such as power transmission equipments, transformers, capacitors, electric motors and generators.
• Produce corona in some other applications such as the manufacturing of ozone, scrubbing particles from air in applications such as air-conditioning systems, in nitrogen laser, when removing the unwanted electric charges from the surface of aircraft in flight, and in electrostatic copying.

The Magnetostatic module can help study a large number of devices and address numerous magnetic and electromechanical phenomena. Below is just a partial list:
• Avoid saturation in magnetic devices. Magnetic saturation is a limitation occurring in ferromagnetic cores. Initially, as current is increased the flux increases in proportion to it. At some point, however, further increases in current lead to progressively smaller increases in flux. Eventually, the core can make no further contribution to flux growth and any increase thereafter is limited to that provided by air - perhaps three orders of magnitude smaller.
• Minimize the cogging torque. The cogging torque of electrical motors is the torque due to the interaction between the permanent magnets and the stator slots of a Permanent Magnet (PM) machine. Also termed as detent or 'no-current' torque, it is an undesirable component for the operation of such a motor. It is especially prominent at lower speeds, with the symptom of jerkiness.

The AC Magnetic module can help study a large number of devices and address numerous magnetic and eddy current effects. Below is just a partial list:
• Minimize eddy current losses and preserve efficiency of many devices that use changing magnetic fields such as iron core transformers and alternating current motors such synchronous motors, 3-phase Induction motors, single phase induction motors, switched reluctance motors, and synchronous generators.
• Optimize the Non-Destructive Testing (NDT) and Non-Destructive Evaluation (NDE) equipment to better detect cracks and flaws in metallic parts.

PhDA Lorentz force linear motion actuator was built to deliberately exhibit a highly nonlinear current for force relation even when the coil was completely immersed in the magnetic field. Magnets were arranged radially around the coil but only half the permissible number were included in order to generate a more complex actuator configuration to test the ability of the EMS electromagnetic finite element analysis software to handle more challenging magnetic path geometries. A detailed set of experiments were carried out on the actual actuator and a similar set of analyses were undertaken using the EMS magnetostatic electromagnetic finite element analysis software. EMS correctly accounted for the gross nonlinearities in the current to force measurements.

Inovio PharmaceuticalsInovio Pharmaceuticals (formerly Genetronics), specializes in developing technology and hardware that has the potential to allow physicians to more efficiently and cost-effectively deliver life-saving drugs or beneficial genes to patients with catastrophic illnesses, including cancer. The company is the technology leader in electroporation therapy (EPT), the application of very brief, carefully controlled, pulsed electric fields, to human cells. This process causes pores to open in the cell membrane and allows pharmaceuticals or genes, injected in the area prior to the application of the electric pulse, to gain access to the cell's interior. The cell pores close up a short time later, trapping the chemotherapeutic agents inside the cancer cell, so they can destroy the cell
EMS and SolidWorks play a vital role in evaluating the electrical fields used with Inovio's electroporation devices, helping to determine and optimize the electrical field strength throughout the volume of space around the electrodes
EMS and SolidWorks have significantly sped up Inovio product development. "The time savings are so dramatic they are, in a sense, unquantifiable," says Andre. "Using EMS, we can change an electrode geometry and analyze an electrical field within a half hour. If we had to do these three dimensional calculations for the more complicated electrode geometries by hand, it would take days."

University of Western Australia"Thank you for giving me the opportunity to use the ElectroMagneticWorks add-in on SolidWorks. It has been amazing to experiment with.
The simplicity and intuitiveness of the software made it a very rewarding experience when simulating my model for the purpose of writing my dissertation to which I have given full credit to EMS. Although it might seem intimidating to use at first, the tutorials proved to be the ultimate savior.
I have truly learned a lot from this software. Knowledge that are taught in the book were only found to be true to a certain extent and it has gave me a new insight in dealing with electromagnetic designs which I have included in my dissertation.
Keep up the good work."

Klaipedos UniversitetasIn our bachelor thesis, a patented “bifilar” coil (BC) type permanent magnet generator (PMG) is constructed for scientific research. The features, working principle and elements of the BCPMG are analyzed.
The BCPMG is developed from the iron-cored “bifilar” coil topology based on Aleksas Pašilis's and Eleonora Guseinovien's patent (Lithuania) in an attempt to overcome the problems with current rotary type Generators, which have so far been dominant on the market.
One of the problems is Armature Reactance, which is usually bigger than Resistance.
The circumstance creates difficulties for designers and operators of the Generator.
"...That is why patented technology is offered to partially remove or absolutely neglect the reactance of the machine. We used The Simulation Software EMS:
To get to the flow direction of the Magnetic Flux Densities through the system, which the same is as expected to be.
To test to a real machine. We found the opportunity of the motion simulation, but there wasn't much time for that investigation.
We have made only a 1/5 sector of the generator to keep the resources at minimum.
We used also a Finite Element Magnetic Model (FEMM) to visualize the effects of the system.
To visualize the effects of the 3 phase current to the flow of flux and densities on the system."

Gdansk University of TechnologyNon-destructive testing (NDT) team at the Solid State Physics Department of the Faculty of Applied Physics and Mathematics cooperates on the broad scale with industry representatives in developing methodology and apparatus for magnetic NDT.
Currently we are optimizing Pipeline Inspection Gauge (PIG) with Magnetic Flux Leakage (MFL) system to evaluate technical condition of pipelines. Such system consists of magnetizing yoke and magnetic field sensors. Working PIG can reach velocity of even 10 m/s due to liquid media pressure. Our job is to model effect of velocity on eddy currents generation and hence distortion of MFL signal.
We have heard about the EMWorks software as a result of searching for Finite Element Modelling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks. Thanks to this design of even very complex models becomes child's play. My first magnetostatic model in EMS was created in just a few minuts! I highly recommend EMWorks software for all those who need friendly interface as well as professional FEM software.

"I used the AC Magnetics module within the EMS software to model electromagnetic coupling to a lab-scale molten metal charge. This modeling was meant to investigate the efficiency and efficacy of inductive coupling as a means to heat and stir a metal solvent for a high temperature crystal growth process. I found the software to be well integrated with Solidworks, with intuitive menus and feature commands. The array of parameters available for adjustment was quite broad; I was able to easily set up a good proxy for my actual experimental setup. The ability to copy/paste an entire study in one step made it especially quick to vary parameters and compare results.
EMS software represents a powerful and robust tool for anyone conducting research, design or development of systems involving electromagnetics."

University of Siegen GermanyI got used to EMS very fast. I just needed two days to get a first result. Especially the simplicity to apply boundary conditions or to refine the mesh at certain surfaces or solids is great! And also the options to plot the results are very nice and intuitive. In the end the results of the simulation matched very well with the experimental values.

Western UniversityI used EMS to teach the third year undergraduate course "Finite Element Methods for Mechatronic Systems Engineering". Students were already familiar with and SOLIDWORKS Simulation and Electromagnetics; they had no troubles learning EMS and working on meaningful assignment problems all within one lab. The use of EMS definitely added value to the course and enhanced students' learning experience.
Amir Vedadi, a student
Oxford Brookes UniversityEMS is quite useful program for finding electric and magnetic fields in unorthodoxly shaped assemblies. It has been especially helpful for me when I was trying to design circuits with high voltage and current applications, which are potentially lethal for students. EMS comes with a set of tutorials that guide users through the model setup and demonstrate a large variety of applications. Overall, a very professional electromagnetic simulation software.
Michelle Wei, Massachusetts General Hospital
Harvard Medical SchoolThe EMS magnetostatics module has been amazing for designing permanent magnet configurations to optimize magnetic field shape. The interface with SolidWorks is really intuitive and I was able to start using it quickly. Even better, the customer service and tech support have been wonderful! I highly recommend this software.
Raffaello Biagini, Student
The University of GenoaI started using EMS because I was looking for a software that could compute accurate 3D magnetic field results, and at the same time provide all the associated variables, such as inductance, force, losses etc. Not only EMS perfectly fulfilled my simulation demands, but I also benefited from the great tech. support, which made my experience with EMS even more enjoyable.
Önder Sönmez - Student
Ankara Yildirim Beyazit UniversityI used EMS software for the induction heating analysis of a gear. The transient magnetic analysis helped me obtain good simulation results which corroborate what is mentioned in the literature.

The software has a user-friendly interface. Moreover, The EMS license comes with a set of pre-defined tutorials and Demo Viewer examples to guide the users and help them get familiar with the software. I had a good experience with EMS. The induction heating examples that are available in EMS Demo Viewer helped me learn more about EMS.
It is a powerful simulation tool that I would recommend to anyone who is doing projects on induction heating.
Bhagwan Singh - Student
Rice UniversityOver the past year, I’ve had the opportunity to use EMWorks to aid in my study of magnetic coils on our apparatus. With this tool, we can model many types of coil designs, such as using thin magnet wire, and water cooling it, or instead going with hollow-core type of wiring (with finite diameters and realistic spiraling modeled in SW) and running cool water through that. We can then see our magnetic field profiles all around the coils, and of course in the center of our Helmholtz configuration, where we would like to ensure very flat magnetic fields. In a complex environment such as a cold-atom experiment, I want to ensure that the vacuum chamber geometry itself would not impede our ability to ramp up and down the current on the magnetic coils, due to eddy currents. By tuning the materials, and in real-time designing components the way they would be engineered, we will be able to fine-tune our apparatus to our needs and constraints. In the future, we will continue to evaluate the eddy currents present in our system as we try different parameters for our magnetic field control (see image).

One great aspect to continue expanding on would be the video tutorials highlighting the many ways to get students started on using EMWorks for their applications. As a beginner, setting up the basic parameters like the “air geometry” was made simpler by watching someone show those steps specifically through SolidWorks.
(The image shows a cut-away view from our new vacuum chamber. We want to verify the compatibility of a new magnetic coil system with the chamber. )

Eastvale STEM academy, Eleanor Roosevelt High SchoolEMS by EMWorks was instrumental in my high school science project. My project required me to find the force produced when a rotating Halbach array is placed above a conductive surface. By carrying out multiple simulations using EMS I determined how changes in the dimensions of the wheels affected their produced thrust and how to create an optimized wheel. Even though I am a high school student with limited simulation experience it was easy for me to learn how to use EMS in a few days. The integration with Solidworks allowed me to rapidly change designs and test multiple configurations. The judges at the Riverside County science fair had a sufficient degree of trust in the EMS simulation results that I was awarded second prize and a certificate of achievement purely based on the simulation data.
Peng Ying
Massey University of New ZealandI used Electromagnetic Simulation (EMS) to investigate the electromagnetic behaviour of Axial Flux-Segmented Rotor-Switched Reluctance Motors (AFSSRMs). A three-dimensional finite element model is developed in SolidWorks. As the EMS is a Gold Certified add-in to SolidWorks, there is no technical boundary in between, enabling me to conduct Finite Element Analysis (FEA) on the model and complete the project on time.
In terms of the setup of the simulation in EMS, the installation instructions are easy to follow, the project tree follows a logical order, and the model parameters can be alternated easily. After each simulation, the result can be saved automatically, and different section views allow the user can analyse simulation results more comprehensively. Results from different studies can be compared, and a range of variables can be plotted. Those plots can be exported to Word documents or saved locally with high resolution.
Engineer experts from EMWorks are friendly and helpful, and they fix many simulation issues. There are plenty of learning resources available on YouTube/Webinars. The tutorial about switched reluctance machines is extremely helpful in building the simulation. The individual project is completed on time with high quality. I appreciate all the help and support from EMWorks, and I will recommend EMS to colleagues who investigate motor behaviours.
Markus Ramsauer
FOSBOS TraunsteinI wanted to express my appreciation for EMS and the benefits it has provided me. Using the software has saved me a significant amount of time and money by eliminating the need for many prototypes. Without EMS, I estimate that it would have taken me at least a week and over 100€ to analyze one variable or problem. Instead, I was able to complete a Simulation overnight and review the results the next day. Additionally, EMS made it easier for me to identify problems without access to expensive measurement equipment.
I also believe that EMS has even more potential than I have been able to utilize in my simpler simulations, and I can see how it could be a valuable tool for both larger and smaller companies during product development. Furthermore, I found it easy to get started with EMS because it is similar to SolidWorks Simulation. I was able to learn the basics within a week through trial and error and a few tutorials.
I also want to highlight the exceptional support provided by you and your company. I have not received such helpful and responsive support in a long time, and I appreciate that you offer direct support for students, something that is not always offered by other companies.

Hydro Extruded SolutionsI am a Research Scientist for an International manufacturing corporation, world leader in the Aluminium tubes manufacturing. Using EMS we were able to do electromagnetic and thermal analysis of novel induction heating tool prototypes, employed in the manufacturing of high frequency welded tubes. The simulations were able to closely resemble induction heating phenomena observed during production and allowed us to forecast benefits and limitations of alternative prototype designs that we were planning to implement in our lines.
The EMWorks engineers were not only very collaborative and available, but have offered great consulting support, building the models and running all required simulation scenarios, as well as preparing final reports, delivering a summary of the work results and the fine-tuned 3D models. I appreciate all the help and support from EMWorks, and I will recommend EMS to colleagues of my team specialized in FEA, as this would be a precious tool to have in-house.
Robin Dhanoa & Lane Hampson
University of Victoria, British Columbia, CanadaOur team is immensely grateful to Academic and Tech Support for their exceptional assistance with EMWorks software, which was indispensable to the success of our project. With their guidance, we were able to use EMWorks to perform an eddy brake simulation for a chainsaw dynamometer that we designed to help chainsaw operators quantify performance improvements resulting from modifications made to their saws. The software allowed us to plot a breaking torque versus rpm graph, which enabled us to map the chainsaw's performance at different rpm levels and gain a better understanding of how breaking torque strength and solid core loss changed with increasing rpm. EMWorks ensured more accurate and comprehensive results during the testing phase. It proved advantageous as it allowed for multiple design iterations (various magnet configurations) and the determination of the corresponding maximum torque values. Thanks to the assistance of EMWorks and their Support team, we were able to achieve a successful project outcome that will benefit chainsaw operators everywhere.

Nathan Mercier
Haute École Bruxelles-BrabantI am currently doing my project in a Belgian company. The goal of my project is to use holding electromagnets to capture ferromagnetic particles in liquid and to put them in motion in this same liquid. To do this I had to choose an electromagnet with well-defined characteristics. That's why I use the simulation with the EMS software. This allows me to visualize the field lines, and to choose the most suitable electromagnet for my application.
I find that the EMS software integrates well with Solidworks and that makes its use quite simple and intuitive. It can be easily taken in hand thanks to the EMS tutorials.

Pranaam Reddy
University of Cape TownI am currently completing my final year Mechatronics Engineering research project with the assistance of EMWorks, in particular, EMS. EMWorks’ Electromagnetic Simulation software has been a tremendous help in my research. The software assisted in the design of my electromagnet which I, otherwise, would have had to design through manual manufacturing iterations. Part of my project entails designing an electromagnet by varying the current though it to try and measure the force it places on an external object viz. a steel bolt. With Autodesk Inventor and EMS from EMWorks, I was able to simulate this force while varying the current through the electromagnet as well as the number of turns, the diameter of wire used, and material used. These design iterations helped me choose the optimal electromagnet for my application and allowed me to only need to manufacture the electromagnet once. Simulating has saved me an incredible amount of time which I needed to use for many other tasks to complete this project within the three-month deadline. Thank you EMWorks. I could not have done it without you!
Abdulaziz Alanazi
Ogden Weber Technical College, United StatesI used the EMWorks’ EMS program to better understand how Axial Flux Motors work, and it is one of the best software programs I have ever used. When I started learning about Axial Flux Motors, I wanted to learn and see how this machine works in real world applications. EMWorks gave me the ability to understand and see how machines works. EMWorks is designed to match the potential of your creativity. EMS software is plugin in Solidworks, and you can design your motor at Solidworks then simulate your motor in EMS with selected motor parts like coils, magnets, rotors and so on. You track the magnets' direction and understand how the magnetic field interacts with air, materials and other magnets. You also can choose the type of coils if it is solid wire or stranded wire. EMWorks comes with simulation examples for different applications to help you to understand how to use the software and is such an easy way to stimulate your design with less cost and get real data to help you to improve your design. Academic team from EMWorks was very helpful during my journey to answer all my questions. EMWorks Team, thank you for developing this software where you make it easier to simulate products for designers and inventors.

Jayendra Mandradiar
Vellore Institute of Technology, Chennai, IndiaI am an undergraduate Mechatronics Engineering student at VIT University, Chennai, India. A few months ago, I got the opportunity to work on research on wireless charging technologies for electric vehicles (EVs). After doing a study of the existing literature in this field, my faculty guide and I decided to do a comparison study on different shapes of coils used for wireless power transfer for EV charging. As EV charging is a high-power application, charging efficiency is a very important factor in the implementation of wireless charging systems. So, to perform the simulation study, I researched different software options and their benefits. Even though I found a few other free or easily available software programs, I found EMWorks EMS to be the most suitable one for my application, especially in terms of ease of use and simple workflow. Also, another major benefit was the integration with Solidworks. Since Solidworks is our primary 3D CAD software, we could directly simulate the models, unlike some other software tools, which require the model to be exported in a particular format and then imported into the simulation software. So any changes I made to the SolidWorks model were immediately reflected in EMS.
Once I imported my models, I was able to quickly create an AC Magnetic study and configure the material properties and the coil parameters. Also, since EMS has Litz wire coils, it provides a very accurate simulation. Once the parameters were set up, the simulation parameters were configured. The parameterization option allowed me to set up multiple scenarios and simulate them all together, which saved a lot of time. I generated about 30 scenarios and simulated them as a batch process. I was able to easily plot the required output variables against these input parameters from the results table. I would like to conclude by expressing my satisfaction with this software for my research, and I look forward to working with EMWorks in the future too.
Sebastian Wann
Technical University, Munich, GermanyI am writing this testimonial to express my satisfaction with the EMS add-on for Inventor. As an engineer passionate about exploring the world of magnetics, I have been searching for a solution to accelerate one magnet with another magnet and precisely compute the force between them that is generated as it moves through a coil. The first aspect that struck me about EMS is its integration with Autodesk Inventor. The integration is incredibly smooth, allowing me to harness the full power of EMS without ever having to leave the Inventor environment. One of the standout features of EMS is its ability to accurately simulate and analyze magnetic fields. With this tool, I was able to simulate the interaction between magnets and calculate the forces.
The software's advanced algorithms and intuitive interface made it easy for me to set up complex simulations and obtain insightful results. I was able to visualize magnetic fields and flux densities, which was great. I could analyze the forces generated at different positions, study the variation of magnetic flux, and evaluate the impact of different parameters on the overall system performance. The software supports a wide range of magnet types, including permanent magnets and electromagnets, and has different coil configurations and materials. This flexibility allows me to explore various design possibilities and optimize systems for maximum performance.
The customer support provided by the Academic Team has also been exemplary. Their prompt and knowledgeable assistance ensured that I could quickly overcome my problems. In conclusion, EMS for Inventor is a very nice tool that has transformed the way I approach magnetism analysis. I wholeheartedly recommend EMS to anyone seeking a comprehensive and reliable solution for magnetism analysis.
