The paper investigates the influence of mechanical manufacturing consideration on the electromagnetic performacnes of a new split stator-permanent-magnet (SPM) machine (SSPMM). The designed SSPMM is evolved from the conventional flux reversal machine (FRM), in which both of these two machines employ PMs placed on the top of stator teeth. The fixation methods of PMs will affect electromagnetic performance, which is not taken into consideration in machine design process. Then, the steady torques of the designed SSPMM and the conventional FRM are analyzed with four key parameters in two representative fixation methods selected as mechanical manufacturing consideration. The evolution process of SSPMM, operating principle and the investigated parameter defination are provided. The finite-element-analysis-calculated results show that the dovetail PM fixing and sticking fixing are suitable for SSPMM and FRM, respectively.
