Abstract
In this paper, non-rare earth traction motor for electric vehicles is discussed. Almost all HEV's and EV's use rare earth permanent magnet motor as a traction motor. The authors have proposed novel induction motor made of Soft Magnetic Composite (SMC) for the resource crisis of rare earth materials. Comparison of iron loss characteristics of SMC induction motor and conventional laminated induction motor is shown. As the result, iron loss of SMC motor is lower than that of the conventional laminated motor at high speed operation. An improvement of the production method of SMC core for the test motor will make efficiency high.
