Abstract

A two-dimensional analytical model of a brushless motor with permanent magnets is developed on the basis of the Fourier variable separation method. The general calculation area of this model includes ferromagnetic areas and permanent magnets with a real configuration. Permanent rotor magnets, stator winding currents, and induced magnetic inductions in the stator teeth are sources of the magnetic field. The calculated values of magnetic inductions in media are found with allowance for stator serration, winding harmonics of the magnetomotive force, and the geometric structure of the arrangement of permanent magnets. The calculated functional parameters of the motor (current, torque) obtained in the model are close to its passport values.

傅里叶变量分离法计算磁电阀电动机。

摘要

在傅立叶变量分离法的基础上，建立了永磁无刷电动机的二维分析模型。该模型的一般计算区域包括具有实际配置的铁磁区域和永磁体。永磁体中的永磁体，定子绕组电流以及定子齿中的感应磁感应是磁场的来源。计算得出的介质中磁感应强度的值考虑到了定子的锯齿，磁通势的绕组谐波以及永磁体排列的几何结构。在模型中获得的计算得出的电动机功能参数（电流，转矩）接近其通行证值。
