ICA’s Malcolm Burwell will present a comparison of induction-motor and permanent-magnet-motor driving/generating performance in a hybrid electric passenger-car at the Techno Frontier in Japan on Wednesday, July 17th.

In the past 2 years, the volatility of prices and availability of permanent magnets has increased.  Manufacturers of electric and hybrid vehicles are considering if a change to induction motors from permanent magnet motors can insulate them from this volatility.   This talk compares the motoring and generating performance of three similar-performance 50kW electrical vehicle traction motors:  (1) Toyota Prius THS-II permanent magnet motor, (2) induction motor with copper rotor, (3) induction motor with aluminum rotor.  As well as comparing weights and costs of these three similar motors, we compare the motors’ energy usage and efficiency using standard vehicle drive cycles.
