摘　　要：研究的单绕组变极方案比双绕组变极方案能够节省材料。单绕组变极方案有多种可能的绕组形式,但就谐波含量及工艺性而言,180°相带绕组有较大的现实意义。本文详细研究了180°相带变极绕组的构成原理,T型接法时的性能计算,两种不同转速下的性能估算方法,最后进行了样机验证。The single winding for pole changing studied in this paper can use less materials than the double winding. There are several possible winding forms in the scheme of single winding for pole changing. However,as far as harmonic component and technological process concerned, the winding with phase belt of 180癶as more practical use. In this paper,the principle of 180°-phase belt winding, performance calculation of T - type connection and estimation of the performance of two different rotating speeds are in detail studied. Finally, some examples of electrical machine are calculated for test purpose.
