Anti-directional-twin-rotary motor drive for electric vehicles
- Yokohama National Univ. (Japan)
A new motor, anti-directional-twin-rotary motor (ADTR-motor) for an electric vehicle drive is proposed. A stator in a conventional motor is reformed to be movable, and the stator (outer rotor) to rotate in the anti-direction of the inner rotor. Several types of ADTR-motor exist, such as induction motor and synchronous motor types. In this paper an induction motor-type ADTR-motor was experimentally constructed. When the ADTR-motor is used for an electrical vehicle, the direction of one of the rotors should be reversed, and both rotors rotate in the same direction, and propel the two wheels of electrical vehicles. The torque of the wheels can be balanced without a differential gear. The fundamental characteristics of the ADTR-motor are clarified, which are the structure, the electrical equivalent circuit parameters, the torque balance theory, the torque-speed characteristics, and the transient torque response under the speed sensor-less torque control. 8 refs.
