| 摘 要： | 从直流电机的基本原理出发，分析了永磁无刷电机的电磁关系，着重推导了电机的电磁力矩和反电动势的一般表达式，在此基础上建立了带中线的永磁无刷电机的电路模型，在Matlab/Simlink平台下的仿真结果证该模型具有计算稳定，执行效率高的优点，与永磁无刷电机的状态方程型相比，电路模型不仅使仿真更加简便，而且具有更强的适用性。

| Abstract: | The modeling for Permanent Magnet Brushless DC Motor (PMBDCM) was introduced. Based on the principle of DC motor and the distribution of the machine in the magnetic field, the electromagnetic relation of PMBDCM was analyzed, and the general formulas of electromagnetic torque and back electromotive force were developed in details. This contributed to a novel circuit model of PMBDCM with neutral terminator. The simulation result on the Matlab/Simulink platform verified the stability of the circuit model and its efficiency. Compared with the state space function model and other simulation models of PMBDCM, the circuit model facilitated the simulation process of PMBDCM and was more adaptable. |
