A new motor (ADTR-Motor: Anti-Directional Twin Rotary Motor) for electric vehicle drive was proposed. A stator in a conventional motor was reformed to be movable, and the stator (outer rotor) and the rotor (inner rotor) rotate in anti-directions. IM type ADTR-Motor and SM type ADTR-Motor are considerable, and in this paper a prototype of IM type ADTR-Motor was experimentally constructed. When ADTR-Motor is used for an EV drive, the direction of one of the rotors should be reversed, and both rotors, which rotate in the same direction, propel the two wheels of EV. The torque of wheels can be balanced without differential gear. The fundamental characteristics of ADTR-Motor are clarified, which are the structure of ADTR-Motor, the equivalent circuit parameters, the torque balance theory, the torque-speed characteristics, the rotors speed transient characteristics, and the transient response under the speed sensorless torque control.
