Electric Motor design process is hypercharged with SOLIDWORKS and EMS

Article by Arvind Krishnan updated February 29, 2016


The electric motor works on the principle of electromagnetics. After Michael Faraday demonstrated in 1821 that electrical energy could be converted into mechanical energy, the search for an ideal electric motor had started. By 1885, Nicola Tesla was able to give a concept of an AC motor and also demonstrate it. It is no coincidence that Elon Musk decided to name his electric car company Tesla Motors.

Unfortunately, for over 100 years electric motors were never seriously considered for powering cars. Honda’s EV Plus and GM’s EV1 made a very short appearance in the 90’s but they failed to take off and were finally discontinued. There were several technical reasons for the failure of early electric vehicles – poor range, expensive, small in size, etc.

Today, electric vehicles are making a comeback for real and for good. In Canada Tesla Motors, GM, Nissan, Ford, Mitsubishi, SmartKia, and BMW all currently offer electric models in their lineup; and more manufacturers will be launching electric vehicles in the coming years.

Now even motorbike manufacturers are taking electric motor technology seriously (learn how Michael Czysz built the world’s fastest electric motorcycle using SOLIDWORKS), and in the future we could see many bikes powered by electric motors.

How Simulation tools can help electric motor design

Simulation tools like EMS for SOLIDWORKS can help improve your electric motor design by:

  • Understanding the complex magnetic flux density inside your motor
  • Eddy currents and power dissipated in the stator
  • Understand what happens in the air gaps
  • Study torque performance
  • Make design changes that can improve torque performance and heating characteristics

The fact is that electric motors will continue to be developed and improved because it has numerous applications other than the car industry. Whether you are building a small motor (MEMS scale) or a large generator (for power generation), simulation tools can give you a formidable advantage. The video below shows how EMS for SOLIDWORKS was used by Team ZEUS to improve their electric bike.


EMS for SOLIDWORKS is the first and only completely embedded Gold Certified software for SOLIDWORKS which helps SOLIDWORKS users study their magnetic, electric and electromagnetic designs seamlessly. It can utilize the geometry created using SOLIDWORKS directly for simulation. Its user interface emulates SOLIDWORKS and hence there is no learning curve associated with the EMS software for SOLIDWORKS users.
