Analysis and Simulation of Axial Flux Switched Reluctance Motor with Modified Stator Structure in Static and Dynamic Conditions

In this paper, a new structure of axial flux switched reluctance motors (AFSRMs) is proposed. Different combinations of rotors and stators affect motor torque and its performance. In this regard, changing the stator structure of the AFSRM leads to better results for torque and magnetic flux. The advantages of the proposed structure are short flux path, segmental rotor with improved flux density. The main geometrical, electrical, and physical characteristics of the proposed structure are presented. Then, the proposed structure is modified by using a higher number of rotor segments than the reshaped stator modules. The proposed structure can be an appropriate candidate for electric vehicles (EVs) and hybrid electric vehicles (HEVs). The results reveal that the proposed and the modified motors deliver the same torque with 36.5% and 46.7% lower active material mass, respectively in comparison of the reference motor. The performance comparison of the selected motors has been investigated by using Quasi-3D analysis.
