Abstract

The Double Stator Magnetic Field Modulation Motor (DSMFMM) realizes the magnetic field modulation effect and optimizes the torque ripple effect by accurately optimizing the flux line. In order to further explore the influence of permanent magnets (PMs) magnetization model on the performance of DSMFMM, this paper conducts a comparative study on the performance of three motors with radial magnetization, Halbach magnetization, and Spoke magnetization. Firstly, three motor models are designed based on the same outer radius and axial length, and the flux lines of the three motors are analyzed in detail. Secondly, the static and dynamic performances of the three models are compared by finite element analysis (FEA) method. Compared with the conventional radial magnetization structure, the DSMFMM structure with Halbach magnetization and Spoke magnetization improves the output torque and torque density of the motor.
