The Saving Energy Repair Based on △-Y Mixed Winding Reform of the Three Phase Asynchronous Motor

分析了三相异步电动机采用△-Y混合绕组型式抑制高次谐波和降低电机损耗的原理。三相异步电动机改△-Y混合绕组,能改善电机性能,降低电机温升,是老式电机节能改造的一种行之有效的措施。并对电机改绕时的接线问题进行了初步探讨。

The theory is analyzed of restraining harmonic component and saving energy by means of using △-Y mixed winding on the three phase asynchronous motor. It can improve the performance of these motors, enhance motor efficiency, reduce the rise of motor temperature. The motor joint should be maximized when motor winding is reshaped.
