新型同步电动机励磁电源

A New Type of Excited Power Supply for Synchronous Motor

以新型的主电路为基础,针对同步电动机起动过程的要求,检测电机转子感应电压信号,精确地计算转差率,控制同步电动机从异步起动到稳态同步过程的可靠运行。

Take the new type of main circuit as base and aim at the synchronous motor jump - start request. to measure the signal of the synchronous motor's rotor, and calculate the rate of change - rotor accurately, to control the synchronous motor operation from start to stabilization credibility.
