电容内补偿三相感应电动机试验研究

Experimental study of capacitor internal compensationfor three-phase induction motor

对电容内补偿感应电动机进行了简单的原理介绍和详细的试验研究 ,并将其与同容量的Y系列普通三相感应电动机工作特性进行了对比分析 ,结果表明 :双绕组电容内补偿感应电动机具有较高的功率因数 。

In this paper, theoretical analysis of capa citor internal compensation for three-phase induction motor with two sets of three-phase windings and the experimental results are given. Compared with Y-series induction motor with th e same output power, the motor has higher power factor, but it hasn ,t obvious advantage in efficiency.
