Single-layer and single-, double-layer pole-switching windings for two-speed asynchronous motors.
Abstract
New schemes of two-speed single-layer and single-layer, two-layer windings with a pole ratio of 2p1 / 2p2 = 4: 2 and 8: 4 are shown. The test data for prototypes of 2-speed 4A71A4 / 2 and 4A80A4 / 2 engines with windings are given. Tab. 3. Il. 3. Bibliogr .: 3 titles.
