摘　　要：针对表面-内置式永磁同步电机因齿槽转矩存在的转矩波动大、噪声和振动等缺点,提出一种通过改变定子槽型的优化齿槽转矩、转矩波动和空载反电势波形的方案。采用有限元法建立表面-内置式永磁同步电机仿真模型,分析了改变定子槽型对电机齿槽转矩、转矩波动和空载反电势的影响。对比分析有限元计算结果,该方案可削弱齿槽转矩、减小转矩波动和优化空载反电势波形。Aiming at the high torque ripple and noise of surface-mounted and interior permanent magnet synchronous motor caused by the cogging torque, an optimization was proposed. The finite element method was adopted to analyze the cogging torque, torque ripple and no-load voltage waveform when the stator slot type was changed. It could be concluded that the optimization method could weaken the cogging torque, reduced the torque ripple, and optimize the no-load vohage waveform.
