Abstract :
The researches on vibration behavior of axial flux permanent magnet synchronous motor (AFPMSM) are presented in the paper. The main work includes calculation of axial fluctuating electromagnetic forces caused by various harmonics in air gap with Maxwell stress tensor method in 3-D magnetic field. The principle resulting in axial electromagnetic force is deduced by numerical algorithm. The axial electromagnetic force densities acting on stator teeth obtained by calculation of motion electromagnetic field is applied to 3-D model of axial flux permanent magnet synchronous motor. The displacement response of all nodes is obtained by transient analysis of 3-D structure for the motor. From experimental investigation of the axial flux permanent magnet synchronous motor, the relationship between axial electromagnetic force and vibration modal frequencies is determined.
