摘　　要：针对分数槽集中绕组的绕组磁动势谐波含量大的问题,本文基于12槽10极的槽极比模型,采用不等槽深结构对电机的绕组磁动势谐波进行优化。本文探究了不等槽深结构的不等槽深值对12槽10极单双层绕组磁动势的工作谐波和其他谐波的影响以及采用不等槽深结构对电机转子损耗的影响。通过仿真计算验证不等槽深结构对绕组磁动势的谐波削弱效果,并根据其对工作谐波和其他谐波的影响选择合适的不等槽深值。The purpose of this paper is to solve the problem of high content of winding magnetomotive force harmonics of fractional slot concentrated windings.Based on the slot-to-pole ratio model of 12 slots and 10 poles,this paper uses unequal slot depth structure to optimize the winding magnetomotive force harmonics of the motor in this paper,the effects of the unequal slot depth structure on the working harmonic and other harmonics of the 12-slot 10-pole single-layer and double winding magnetomotive force and the influence of the unequal slot depth structure on the rotor loss of the motor are studied.Through simulation calculation,the harmonic weakening effect of the unequal slot depth structure on the winding magnetomotive force is verified,and the appropriate unequal slot depth value is selected according to its influence on the working harmonic and other harmonics.
