Experimental Verification of a Motor with Two Controllable Rotors

Abstract

　A number of automobiles have been fitted with electric motors and their inverters. In order to reduce the space of motors, we have proposed a motor with two controllable rotors, which consist of 2 rotors and 1 stator. However, the previous motor was difficult to be practically used due to its complicated structure. Therefore, we proposed a novel motor with 2 controllable rotors. In this paper, the computed characteristics by carrying out measurements on a prototype are verified. First, the cogging torque and back-EMF are measured. Finally, the N-T characteristics are measured under vector control.
