摘要对于永磁同步电动机, 特别是分数槽电机, 极槽配合的选取对电机的电磁噪声有着很大的影响, 一个合适的极槽配合可以使电机的电磁噪声大为减小。故本文首先推导出不同极槽配合所含径向力波次数及力波频率的表达式, 进而提出能够产生单边磁拉力的条件。其次, 用3台不同极槽配合的电机进行试验, 得出在不同频率下的电机噪声声压级频谱图, 进而验证了前述结论的正确性。

Abstract：For Permanent Magnet Synchronous Motors, especially fractional-slot motors, the choice of slot/pole combination have a bigger influence on electromagnetic noise. A suitable slot/pole combination can reduce the electromagnetic noise obviously. In this paper, orders and frequencies of the radial magnetic force in different slot/pole combination have been deduced firstly. In this process, the conditions of producing unbalanced magnetic force have been presented. Secondly, three motors with different slot/pole are used to experiment. The sound pressure level spectrum of PMSM have been obtained in different frequencies. The experiment results prove the conclusion that have been mentioned above is correct.
