Optimal Design of Switched Reluctance Hub Motor

This paper presents two criteria for evaluating the motoring operations of switched reluctance hub motor (SRM) drives for electric vehicles (EVs). They imply motoring torque and copper loss. To fulfil the best motoring operation, by using two weight factors and two base values, the developed optimization function selected as the correct balance between the maximum average torque and the maximum average torque per copper loss. The stator and rotor pole arc angles are selected as the optimized variables. Simulations results have demonstrated the proposed optimal design method. Therefore, this paper offers a valuable and feasible approach for implementing the best motoring operation of SR Hub Motor drives for EVs.
