方波驱动无刷直流电动机稳态运行特性的仿真分析

The Simulation and Analysis of the Steady State Characteristic of Brushless DC Motor

利用ＰＳＰＩＣＥ仿真分析方波无刷直流电动机的稳态运行特性，研究了电机的力矩电流特性，并在此基础上设计了适用于力矩控制的电流采样电路．

In this paper, the steady state characteristic of brushless DC motor is simulated and analyzed by using PSPICE, the torque-current characteristic is studied and baased on the analysis, a current-measure circuit for torque control is designed.
