Overcoming the Challenges of Hybrid/Electric Vehicle Traction Motor Design

Hybrid electric vehicles (HEVs) and electric vehicles (EVs) have been rapidly gaining traction in the global automobile market by providing high fuel efficiency and near-zero emissions at increasingly affordable prices.
Many automobile original-equipment manufacturers (OEMs) are working on new HEV and EV designs; one of their greatest challenges is designing traction motors, which, in most cases, are interior permanent magnet (IPM) synchronous machines. Minimizing electrical and magnetic losses is critical to deliver maximum range and fuel efficiency to consumers. At the same time, engineers need to consider structural, thermal and electromagnetic issues that play a crucial role in vehicle performance, reliability and cost.
OEMs face the challenge of solving these issues quickly to squeeze through tight market windows in the rapidly evolving HEV and EV markets. Integrated multiphysics simulation technology helps to address these challenges by enabling engineers to rapidly evaluate — prior to physical prototyping — functionality, performance and cost of a wide range of design alternatives. This approach makes it possible to optimize traction motor design performance in a fraction of the time and cost required by traditional design methodology.
By leveraging advanced state-of-the-art simulation, automotive organizations can gain a significant competitive advantage in the race to replace conventional powertrain technology.
