磁気ギアを用いたEV用モータシステムの高出力・高トルク密度化

抄録

Technical innovations for the downsizing of motor systems are necessary to realize energy savings and roomy and comfortable car interior space in electric vehicles. In this paper, a novel motor drive system with multiple high speed motors and a Magnetic Multiple Spur Gear (MMSG) is proposed for electric vehicles. Furthermore, the factors leading to a high power density and high torque density in an MMSG system are clarified.
