Use of electric vehicles is increasing due to zero carbon emission, its sustainability and energy saving capability. This paper compares performance, efficiency and reliability of different motors which can be used as drive train of electric vehicles. Performance of induction motors, brushed DC motors, permanent magnet brushless DC motors, switched reluctance motors and their respective controller have been simulated. Merits and demerits of each system have been highlighted. Performance of BLDC and switched reluctance motors as in-wheel motors under normal and critical conditions are compared. The paper also covers the additional benefits of integration of BLDC motor-drive systems with inbuilt adaptation of control and self fault diagnosis in-wheel systems.
