介绍了以M68HC11A8为核心的多功能同步电动机励磁综合控制器。它能消除同步电动机起动过程中的脉振，投励时的冲击，增加了失步保护电路，并具有可控硅误导通检测和失控检测功能，提高了同步电动机运行的可靠性，从而延长了其使用寿命．
The M68HC11A8-based multi-function synchronous motor excitation integrated controller is introduced. It can eliminate the synchronous motor starting process of pulse vibration, the impact of investment incentives, an increase of out-of-step protection circuit, and with SCR error detection and control of non-conduction detection and improve the reliability of synchronous motor operation, thus extending the Its service life.
