摘　　要：极槽配合的选择一直作为电机设计的首要问题备受关注。选择4种极槽配合,结合直驱电机的绕组系数和齿槽转矩进行分析,主要将齿槽转矩、空载反电动势、气隙磁密与转矩脉动等参数作为衡量电机的性能指标进行对比分析,得出极槽配合为27/28的直驱电机具有较低的齿槽转矩和转矩脉动、气隙磁密与空载反电动势的谐波含量较小,综合性能较好。为直驱电机在数控机床上的选择及优化提供了一个重要的参考依据。The selection of slot-pole combination has always been the primary issue in motor design and has received much attention.Four kinds of slot-pole combinations were selected,and the winding coefficient and cogging torque of the direct-drive motor were combined for analysis.The cogging torque,no-load back electro-motive forces,air-gap flux density and torque ripple were mainly used as the parameters to measure the motor for analysis and comparison.It is concluded that the direct-drive motor with 27/28 slot-pole combination has lower cogging torque and torque ripple,and the air-gap flux density and no-load back EMF have smaller harmonic content,and better comprehensive performance.The method provides an important reference for the selection and optimization of direct-drive motors on CNC machine tools.
