The study of the three-phase pole-switched winding.

Abstract

The results of the development and research of a three-phase pole-switching winding with the ratio of the numbers of pole pairs p1 / p2 = 4/3 are given. It is established that the equalizing current in the short-circuited circuits of the parallel branches of the YYY / YYY scheme causes not only a decrease in the engine's energy performance, but also noise. One of the possible winding transformation options is shown to reduce the surge current. The nominal technical and economic indicators of the 4AM 132 series engines with the developed winding are given. Tab. 1. Il. 4. Bibliogr .: 4 names.
