Steady state model of Dual Rotor Motor for electric vehicle application

Abstract

Dual Rotor Motor (DRM) can be a very suitable option for electric vehicle application due to its compact size, high torque and high power density. In this paper, an analytical model of DRM is developed, from where the steady state torque equation is investigated for different firing angle of the inverter feeding the motor. The finite element analysis of the same machine is performed to validate the developed analytical model. Speed-torque characteristics for different operating modes have also been analyzed for the better understanding of DRM behavior, which are required to control the DRM.
