Driving characteristics of anti-directional-twin-rotary motor on electric vehicle simulator

Abstract

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