Traction control of anti-directional-twin-rotary motor drive based on electric vehicle driving simulator

An anti-directional-twin-rotary motor (ADTR) was tested on the electric vehicle (EV) driving simulator, which behaves as if the ADTR-motor is installed in the EV, and was driven in the EV driving conditions. The ADTR-motor has novel motor structure suitable for EV drives, in which the stator in a conventional motor was reformed to be movable, and the stator (outer rotor) rotates in the anti-direction of a rotor in conventional motor (inner rotor). Several motor structures of ADTR-motor are possible; a permanent magnet (PM) type, an induction motor (IM) type and so on. In this paper, driving characteristics of a permanent magnet type ADTR-motor on the EV driving simulator were measured, and we proposed a traction control for the EV using ADTR-motor
