Vibration and Noise of High Speed Amorphous Alloy Permanent Magnet Synchronous Motor with Different Slot Width
This paper presents an analytical model of the electromagnetic vibration and noise for a High Speed Amorphous Alloy Permanent Magnet Synchronous Motor (HSAAPMSM) whose stator cores are made from amorphous alloy magnetic material. Firstly, air gap flux density of HSAAPMSM with different slot width is calculated by two methods of Finite Element Analysis (FEA) and analytical. By comparison, accuracy of the modeling is validated. Then, through the finite element coupling analysis, the electromagnetic force acting on the surface of the stator teeth is obtained. In addition, the space harmonic analysis of air gap flux density and electromagnetic force is carried out. The electromagnetic vibration and noise of HSAAPMSM with different slot width are calculated respectively and the influence of laminating effect is taken into account.
