摘　　要：针对舵机用大功率永磁同步电机转动惯量低、转速高、功率密度高和短时工作制的特点,对定子绕组形式和槽极数配合的合理选择做了介绍,并确定了电机基本尺寸。电机采用18槽4极分数槽双层短距分布绕组,电磁场有限元分析和试验结果表明,电机永磁电动势波形正弦度高,电机齿槽转矩低,转矩脉动低,输出转矩高,转动惯量低,具有较高的动态响应性能。According to high power permanent magnet synchronous motor （PMSM） characteristics of low rotational inertia, high power density and short-time duty type, the reasonable selection of stator winding forms and coordination of slots and poles was presented, and the basic size of motor was determined. Motor adopted fractional slot-pole combination of 4- pole/18-slot with double windings of short pitch layers. Finite element analysis（FEA） and experimental results show that the PMSM have low cogging torque, torque ripple, moment of inertia and high output torque, dynamic response performance, waveform sine degree in electromotive force.
