永磁无刷电动机导通角的自寻最优控制系统

Automatic Searching System of the Optimal Conducting Angle for Permanent Magnet Brushless Motor

介绍了四相永磁无刷电动机导通角自寻最优控制的一种方法，分析了不同导通角时四相永磁无刷电动机的运行状态及导通角自寻最优控制的实现方法；给出了ＭＣＳ－８０９８单片机永磁无刷电动机导通角自寻最优控制系统的工作原理。

The control system for automatic searching the optimal conducting angle of 4 phase perma nent magnet brushless motor is presented in this paper. The relation between the conducting angle and the winding current is obtained in the light of constant speed and torque. Finally, the paper shows you the working principle, the hardware and the software block diagram of the control system consisted of MCS 8098 chip microprocessor for the permanent magnet brushless motor.
