Abstract

Dual rotor motors (DRMs) for the electric vehicle application are a competitive alternative to the multi-motor drivetrain configuration to meet the high-power density and better vehicle drive performance. In this paper, a steady-state model of a hybrid DRM is developed using electromechanical energy conversion principles. The developed model comprises electrical equivalent circuit and torque equation. The model helps in understanding the motor operation and can be used for quick performance evaluation. The finite element method has been used to validate the developed model and a good agreement has been achieved for the results obtained.
