Abstract

The flux-switching machine (FSM) stands as an innovative form of brushless doubly salient permanent magnet machinery characterized by a stator flux possessing bipolar attributes. Distinguished by excitation and concentric windings nestled within the stator and a rotor design reminiscent of switched reluctance machines, the FSM presents a compelling array of advantages. Notably, it boasts a high-power capacity, remarkable torque density, and commendable efficiency, particularly at low rotational speeds. Its operational simplicity further enhances its appeal. This comprehensive paper delves into a meticulous evaluation and comparative analysis of various topologies inherent to the FSM. Through an in-depth exploration of its diverse structures and operational modalities, the study seeks to illuminate the nuanced differences between these topologies. By scrutinizing their respective functionalities, the paper aims to discern the unique strengths and potential limitations of each FSM topology. It provides insights crucial for optimizing the design, performance, and application of flux-switching machines across diverse industrial domains, thereby paving the way for enhanced efficiency and efficacy in electrical machinery systems.
