将三相异步电动机定子绕组分成一次与二次绕组 ,其一次绕组和滞后一相的二次绕组与电容器构成三角形联结 ,利用电容电流对二次绕组的作用来提高电动机的效率和功率因数。
The three-phase asynchronous motor stator windings are divided into primary and secondary windings. The primary windings and the secondary windings of one phase of hysteresis are connected with the capacitors to form a triangular connection. The capacitor current is utilized to improve the efficiency and power factor of the secondary windings.
