Abstract

A new power train for electric vehicles is proposed using an anti-directional twin rotary (ADTR) motor. A stator in a conventional motor was reformed to be movable, and the stator (outer rotor) rotates in the opposite direction to the inner rotor. In this paper, several characteristics of an induction motor-type ADTR motor are reported. When an ADTR motor is used in electric vehicles, the direction of one of the rotors should be reversed and both rotors rotate in the same direction, propelling the two wheels of the electric vehicle. The torque of the wheels can be balanced without a differential gear. The fundamental torque-balancing characteristics of an ADTR motor are clarified, namely, the torque balance theory, the torque-speed characteristics, the rotor-speed transient characteristics and the transient torque response under speed sensorless torque control
