Abstract: This paper studies the influence of the armature winding structure on the electromagnetic performance of the stator permanent magnet flux-switching permanent magnet ( FSPM) machine. The machine adopts the design of fractional slot concentrated winding and double salient pole structure. By integrating the permanent magnet on the stator,high torque density and low harmonic characteristics of no-load back electromotive force are achieved. Aiming at the current situation of insufficient research on the winding structure of stator permanent magnet machines, a three-phase 12 slot 13 pole FSPM machine is taken as the research object,and the working mechanisms of the double-layer and four-layer winding structures are mainly analyzed. The comparative analysis through finite element simulation shows that the two winding structures present significant differences in electromagnetic parameters. Among them,the four-layer winding shows a better harmonic suppression ability,which provides an important theoretical basis for the optimization design of the winding of the stator permanent magnet machine.
