摘要: 针对一台压缩机用9槽6极内置式永磁同步电动机(IPMSM)样机在某关键频段存在较高噪声的问题,确定了引起该噪声的关键磁密谐波及径向电磁力谐波,提出并设计了极靴隔磁槽方案来抑制关键磁密谐波,并基于FEM动态冻结磁导率法计算了隔磁槽措施对关键磁密谐波的抑制作用,最后通过各方案样机的噪声测试,验证了极靴隔磁槽对关键频段噪声的良好抑制效果。

Abstract: In order to solve the high noise problem in a key frequency band for9-slot 6-pole IPMSM prototype of a compressor, the key harmonics of magnetic density and radial electromagnetic force were determined. Flux barriers in pole shoe were proposed to suppress these key harmonics. The suppression effect was calculated based on FEM dynamic frozen permeability method for three prototypes.Noise tests on the prototypes showed that the flux barriers in pole shoe can effectively suppress the noise in key frequency band.

Key words: permanent magnet synchronous motor(PMSM), frozen permeability, noise reduction, vibration and noise, radialelectromagnetic force
