针对永磁同步电机在批量生产过程中，受到电机尺寸加工偏差及材料属性偏差等噪声因子的影响，存在批量生产电机的转矩脉动峰值会产生分散性的问题。为了研究存在噪声因子条件下转矩脉动峰值的分布特性，通过采用敏感性分析的方法得到了影响转矩脉动峰值的主要噪声因子包括磁钢形位公差和材料属性偏差，槽口尺寸偏差及气隙尺寸偏差。通过理论分析和解析计算得到了存在噪声因子的情况下，批量生产的电机产品转矩脉动峰值的统计分布规律。得出在电机可行设计域内，不同电机设计方案，其批量产品转矩脉动峰值的均值和标准差呈正比关系，并通过粒子群优化结果证明了结论的有效性。

In mass productions of permanent magnet synchronous motors( PMSM) , the torque ripple dis-persion is caused by the sizes errors and the material properties variations, which can also be named as noise factors. In order to analyze the distribution of torque ripple in mass productions of PMSM , the sen-sitive analysis was operated and the most sensitive noise factors which greatly affect the torque ripple were obtained that are the magnets misplacement properties error, the slot opening error and the air-gap size er-ror. Then the distribution of the torque ripple in mass productions was estimated by the firstly the theoreti-cal analysis and by the analytical calculation. The relationship of the mean value and standard derivation of the torque ripple in mass production are linear which is then proved by the optimum design results.
