Abstract—Permanent-magnet motors are widely used in-wheel motors of electric vehicles and hybrid vehicles. Based on a movable stator design, this paper presents a new type permanent-magnet motor, whose torque can be adjusted in order to meet different driving requirements. The stator geometry is varied by means of changing movable stator positions. Accordingly, the air-gap length in permanentmagnet motors is changed so that torque can be adjusted. To derive an analytical model, Fourier series expansions are employed to formulate air-gap geometry variation. The analytical model is validated by finite element numerical results. Concerning motor torque variation capability achieved in this study,
the ratio of the largest vs. the smallest torque is 2.3.

 

 

 

A desirable feature of permanent-magnet (PM) motors is high torque at low speed, and therefore suitable as a direct-drive actuator in electric vehicles (EV) or hybrid vehicles. The high torque feature helps acceleration performance of EV. Vernier machines [1, 2] belong to PM motors and are adequate as an in-wheel motors. High torque and high efficiency feature are caused by a magnetic gearing effect. Toothed-pole structures play an important role in torque-maximizing design of vernier machines. To increase torque, dual-excitation permanent magnet vernier machines [3] including inner-stator and outer-stator were presented.

 

The same motor volume that can generate larger torque will gain advantage in EV performance. Both increases of armature magnetomotive force and inner diameter of stator are approaches to raising torque performance with the same machine volume [4]. Different stator shapes and magnet
configurations will cause different flux densities and torque performances, respectively. A relationship between the stator shape and flux density was developed in order to predict motor performance [5]. A finite element method was used to analyze the electromagnetic torque of PM machines with concentrated winding, whose results show that the torque is affected by magnetic saturation
