Abstract: This paper presents an experimental direct driving system with in-wheel switched reluctance motor (SRM) for electrical vehicle (EV). The integrated EV direct driving system includes three main parts: the SRM model, driving circuit and control unit. The proposed 8/6 SRM is a novel motor with high performance; the specified external rotor type fits the requirement of in-wheel EV for saving space. The driving module consists of four independent drivers, is controlled by the micro-controller, DSP. The detailed hardware installment is presented to realize the EV direct driving system, with the block diagram to show the design of the driving system. Control flow of the specified system is introduced to describe the control procedure; various control methods are proposed and studied to verify the performance of SRM and the driving system. Speed control and constant torque/constant power control are implemented with PI control and hysteresis loop control, to test the speed response and reliability of the direct driving system. An experimental direct driving system is developed; the experimental results are obtained to verify the performances of the EV driving system.
