Summary:This paper presents the ultrasonic frequency characteristic of electromagnetic vibration and noise for permanent magnet synchronous motor (PMSM). The analysis flowchart of the vibration noise was discussed, and the electromagnetic vibration is researched from the simulation results integrated theoretical analysis. This paper describe that the slots and pole combination has obvious influence on the eigenvalue distribution within a certain frequency range. In addition, the mode frequency and shape of stator are calculated when different fixation method adopted. Analyzing above provided references for motor design and fixed method, and ensure the frequencies of rated point and other important working points can effectively avoid the resonant points, therefore to reduce the electromagnetic vibration and optimize the design scheme.
