摘要
本电机定子上装有主、副2套三相绕组,是利用自耦升压、最佳电容内补偿原理设计而成的。其功率因数在电机功率变化的全域范围内都能达到接近于1的高水平,节能效果显著,且所需电容量小。导出了这种电机的基本方程式,给出了等值电路及相量图,并论证了存在直角补偿特性的可能性。
A new type of asynchronous motor with two stator-windings is presented,which is designed using the method of self-compensating,so it has the characteristics of right-angle compensation and its power factor is nearly equal to 1 within full power changing region. Also,this kind of motor saves energy dramatically,and the capacitance of compensating con- denser is small.The basic character equations,equivalent circuit and phase diagram of the motor are derived.The possibility of right-angle compensation is proved.
