 abstract={The axial-radial flux type permanent magnet synchronous machine (ARFTPMSM) can adjust the main magnetic field by controlling the axial flux, so it can overcome the problem that the flux of the permanent magnet synchronous motor (PMSM) is difficult to adjust. Due to the existence of the axial device in the ARFTPMSM, the finite element method (FEM) is used to establish a three-dimensional model for analysis. By analyzing the magnetic density distribution of the rotor, it is found that there is a serious magnetic leakage phenomenon at both ends of the tangential permanent magnet. The rotor material at the end of the tangent permanent magnet is replaced by non-ferromagnetic material to reduce the magnetic leakage. On this basis, the influence of the width of the non-ferromagnetic material on the performance of the motor is compared. By Fourier decomposition of the back-EMF waveform, the total harmonic distortion (THD) rate of the back-EMF under different axial magnetomotive force (MMF) was calculated. Finally, the eddy current distribution and the eddy current loss of the rotor are analyzed, and the variation law of the eddy current loss is summarized. The conclusion can provide reference for the optimal design of the ARFTPMSM.},
