I'm a mechanical designer in a company that builds magnetic inspection tools for the oil and gas pipeline industry. These tools use a magnetic flux leakage (MFL) principle to find cracks, corrosion pits and other defects in the pipe wall.

I used EMS in many magnetostatic studies to design the magnetic circuit of one of the tool components, and I was very happy to see how accurate the results were, after laboratory tests confirmation. Because EMS is easy to use and allows me to view the study results by cutting sections anywhere in the 3D model, I can optimize the magnetic design of our tools to a level impossible to achieve without a powerful software like this one.

Now I'm planning to extend the magnetostatic studies to all the tool components, using EMS with much bigger and more complex models.

I am the R&D manager at Verdun Anodizing. Verdun has been in business of anodizing of aerospace and military components for over 70 years.

I used EMS to simulate primary and secondary current distributions in our electrochemical cells using the Electric Conduction module.Using this tool, we succeeded in optimizing the setup of the electrochemical cells by studying various material of the electrodes and the bath parameters such as the acid concentration and temperature.A trial-and-error procedure would have taken us years to achieve the optimal design achieved using EMS. It was a well worth it investment.

ABB Automation Products business unit in Västerås, Sweden designs and produces large and powerful DC motors for major industrial applications.  The output power of such motors actually ranges from 30 KW to 1400 KW!

The Research & Development Department of the DC Motors division is currently developing a new generation of larger DMI motors.  They use the CAD software package SolidWorks and its Gold Certified electromagnetic Add-in, EMS, from ElectroMagneticWorks to optimize their design.  With the help of these powerful design tools, they aim to develop powerful DC machines.  Such machines will achieve output power and torque significantly higher and more compact than any DC motors available on the market today.

A 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 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."
