根据永磁辅助同步磁阻电机(PMASRM)复杂的结构特点,基于ANSYS Maxwell 2D软件平台,介绍参数化绘制几何模型的过程,并对结构参数进行优化设计。对恒转矩区间采用最大转矩电流比(MTPA)控制策略、恒功区间采取弱磁控制求解电机电压、电流、内功率因数角、转矩的具体步骤进行了详细说明,为同类电机设计提供了较为实用的分析手段。

According to the complex structure characteristics of the permanent magnet assisted synchronous reluctance motor (PMASRM), the process of parameterization and geometric model establishment was introduced based on the ANSYS Maxwell 2D software platform, and the structural parameters were optimized. Furthermore, the specific procedures of using maximum torque per ampere (MTPA) control strategy in constant torque region and field weakening control in constant power region to get motor voltage, current, internal power factor angle and torque were illustrated in detail. It provides a more practical analysis method for the design of the same kind of motor.
