摘要针对舵机用大功率永磁同步电机转动惯量低、功率密度高、短时工作制的特点,对定子绕组形式和槽极数配合做了较为合理的选择,确定了电机基本尺寸。电机电磁场有限元分析结果表明,电机具有较高的电气性能。由于电机功率密度高,电磁有效部位细长,电机转速较高,电机温升问题突出。根据传热学理论,建立了永磁同步电机三维瞬态温度场求解模型,确定了表面散热系数。通过有限元分析得到了电机定子绕组铜耗、定子铁心铁耗以及永磁体和转子护套内的涡流损耗。将定子槽内和端部处导线分别等效成若干个导热体、分布排列,得到了更加符合实际情况的电机三维瞬态温度分布结果。试验结果表明设计方案合理。

Abstract：According to high power permanent magnet synchronous motor(PMSM) characteristics of low rotational inertia, high power density and short-time duty type, the paper presents reasonable selection of stator winding forms and coordination of slots and poles, and determines the basic size of motor. The motor shows high electrical performance with finite element analysis of the electromagnetic field. Temperature rise of the motor is serious due to its high power density, slender electromagnetic effective fraction and high rotational speed. On the basis of heat transfer theory, the solving model of 3D transient temperature field for PMSM is established and surface heat transfer coefficients are given. Stator winding copper loss, stator core iron loss, permanent magnet eddy loss and eddy loss in the rotor sheath are obtained by finite element analysis. Wire in stator slot and end region is equivalent into several heat conductors which distributed and arranged respectively, and more reliable 3D transient temperature distribution is obtained. Experimental results show that the design of motor is reasonable.

Key words： PMSM low rotational inertial finite element method loss 3D temperature field
