Abstract :Due to high volume of the studies in the field, flux switching permanent magnet (FSPM) machines are explored in this article. Particularly, this paper is examined the studies carried out to reduce cogging torque (CT) in FSPMs. The reduction of CT improves the smoothness and efficiency of electric machines, improving the effectiveness of control systems. In addition, the reduction in vibration and noise levels increases accuracy and reliability, particularly in sensitive applications. The research begins with a systematic examination of CT in FSPM machines. Through this analysis, certain parameters contributing to the mitigation of CT were determined, and relevant advancements from prior literature were thoroughly examined. Mostly, the structural changes were implemented by enhancing the rotor and stator to mitigate the CT. The rotor and stator efforts are discussed and classified in detail in this paper. These investigations substantiate the degradation in CT and the results make a significant contribution to the existing literature within the scope.
