The Magnetic and Electric Field and Force Software for Electromagnetic Applications

EMS logo

EMS is a magnet and electromagnetic software and simulation tool that computes 3D magnetic and electric field and flux, electric potential, voltage, current, magnetic force, electric force, torque, eddy current and losses, skin effect, proximity effect, and electromagnetic induction.  The applications include transformers, motion industries, electric motor, eddy current, sensors, NDT, NDE, electrical machines, insulator, high voltage, magnets,  biomedical, and induction heating.  It offers the state-of-the-art accuracy and power of the finite element method and meshing technology.  Whether your preferred CAD is SOLIDWORKS®, Autodesk® Inventor®, or Ansys SpaceClaim, EMS is your indispensable electromagnetic companion.  It is seamlessly embedded in all the three CAD packages.  EMS is Gold Certified by SOLIDWORKS® Corporation.

Solidworks, Autodesk Inventor, and Ansys Spaceclaim Seamless Integration

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 wont 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.

Multi-Physics Capabilities

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.   

Electro-Thermal Analysis

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.   

Electro-Mechanical Analysis

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.  

Solidworks Motion integration

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.  

Grabcad, 3dcontencentral, traceparts

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.
