Field-Circuit Coupled Analysis of an In-Wheel Switched Reluctance Motor with Outer Rotor for EV Applications

Switched reluctance motor (SRM) is potential to be applied in electric vehicle as an in-wheel drive motor because of its unique feature, such as being allowed to operate in a wide speed range with high efficiency. In this paper, a field-circuit coupled dynamic model is developed with 2D finite element method in Maxwell being proposed to compute the performances of a 10kW/800rpm SRM using the angle position control (APC) strategy. The nonlinear magnetization characteristics have been considered and calculated by FEA. The magnetic fields, windings current, the electromagnetic torque and the terminal characteristics of the prototype SRM are investigated.
