提出了一种降低齿槽转矩的拓扑优化方法，并将其应用于内置式永磁电机定子铁心的设计。该方法使用反应扩散方程，并基于两个目标函数分别进行优化：1)最小化转子位置的齿槽转矩本身；2)最小化磁能变化。优化结果表明，具有虚拟时隙的配置是理想的，但虚拟时隙的数量随所用目标函数的不同而不同。
This study presents a topology optimization method to reduce cogging torque, applied to the design of the stator core of an interior permanent magnet motor. The proposed method uses a reaction-diffusion equation and optimization is separately performed based on two objective functions: 1) minimization of the cogging torque itself, for a number of rotor positions; and 2) minimization of the magnetic energy variation. The optimization results show that configurations having dummy slots are desirable, but the number of dummy slots differs according to the objective function used.
