摘要

本文提出了一种新的无刷直流电动机设计方案，该方案可在无刷直流电动机中加入高压叶片泵。然后，讨论了由单相交流网络、变换器、永磁无刷直流电机和PWM调速方法组成的系统的场路模型。最后给出了用所建立的场路模型计算的电流、电压、转矩、转子转速、定子铁损耗、绕组损耗以及磁体和转子轭损耗的波形。

Time-stepping finite element analysis of a brushless DC motor with the PWM speed control

In this paper, a new design solution for the brushless DC motor, in which a high-pressure vane pump can be built, is presented. Then, the developed field-circuit model of the system consisting of a single phase AC network, a converter, and a PM BLDC motor and PWM speed control method is discussed. Finally, waveforms of currents, voltages, torque, rotor speed, stator iron losses, winding losses and summary magnets and rotor yoke losses computed by the developed field-circuit model are shown.
