摘　　要：对微型电机的电磁机构和转子的电磁力分布进行了分析。根据电机技术参数并利用ANSYS Maxwell软件建立了专家模型。将专家模型导入Maxwell2D形成二维电机的全模型,并利用场计算器得出径向和切向的气隙磁密及转子所受电磁力的密度曲线。对转子所受电磁力进行傅立叶分析,并讨论了有槽和无槽电机电磁力对齿槽转矩及电机振动的影响。The electromagnetic mechanism and the rotor electromagnetic force distribution of the micro motor are analyzed. The expert model is established according to the motor parameters by using the ANSYS Maxwell software. The two-dimensional motor model is formed by leading the expert model in the Maxwell2d, thus the air gap flux density is calculated and the density curve of the electromagnetic force is achieved. The rotor electromagnetic force is analyzed, and the influence of the electromagnetic force on the cogging torque and the motor vibration is compared with slot and without slot.
