Multiphysics Simulation Key to Superior Traction Motor Performance

Automobile original equipment manufacturers (OEMs) face the difficult challenge of designing a new generation of traction motors — which play a critical role in hybrid electric vehicle (HEV) and electric vehicle design — by transforming electrical energy into physical energy used to turn the wheels of the vehicle. The efficiency with which traction motors can perform this conversion is critical because of its impact on the range and battery life of the vehicle. Another design challenge is the need to minimize rare earth metal content, since these materials are increasingly in short supply.

Simulation-driven development provides the ability to rapidly evaluate many traction motor design alternatives and to predict their performance in a short amount of time. Engineers at leading HEV and EV manufacturers are using multiphysics-based simulation tools to produce superior traction motor designs and bring them to market ahead of competitors.
