异步电机的曲折接线与电容内补偿

Flexuous-connecting Wiring and Inner Compensation by Capacitors in the Asynchronous Motor

将三相异步电动机的定子绕组连接成其电势相量为不等边六边形的曲折接线,利用连接于3个副线圈的电容器使其绕组磁势的相量形成正六边形,具有降低电机电流有效值达20%以上的显著节能效果。

The stator winding of three-phase asyn- chronous was reconnected into an inequilateral-hexagonal flexural-wiring form while the capacitor connected with 3 auxiliary windings, making the phase potential of the wind- ing to form a regular hexagon. This connection possessed remarkable energy-saving effectiveness to reduce over 20% value of effective current of the motor.
