Axial flux switched reluctance motors (AFSRMs) offer advantages such as a large air-gap surface area, compact structure, and high torque density. This paper proposes a novel five-phase AFSRM structure featuring wide-and-narrow stator poles (NWS-AFSRM) and presents a comparative study of the electromagnetic characteristics of the five-phase NWS-AFSRM with varying rotor pole numbers. Firstly, while maintaining a constant stator pole count, four feasible rotor pole configurations are determined: 20/12, 20/14, 20/16, and 20/18-poles. Subsequently, based on these four pole combinations, their corresponding phase excitation sequences are investigated. Using the finite element analysis (FEA) method, both static and dynamic electromagnetic characteristics are evaluated to analyze the influence of rotor pole number on the motor’s electromagnetic performance.
