摘要
变极调速异步电动机是在电源频率保持不变时，利用改变定子绕组的接法，在一套统组中获得两种或两种以上的转速，这些转速既可以是倍极比，也可以是非倍极比．本文利用极幅调制与槽电势星形矢量的原理，设计出性能优良，结构简单的单绕组多速异步电动机．
With the stable frequency of power source the asynchronous motor of speedadjustment in Polarity inversion could reach two or more than two kinds of speed in one statorwinding by changing the way of connecting stator winding. These kinds of speed were of multiple or nonmultiple magnetic POle ratio. With the theories of pole-amplitude modulation'and 'slot voltage star vector' an asynchronous motor of one stator winding and of various speedwas designed with a fine property and a simple structure.
