Technical and economic comparison of four-speed asynchronous electric motors with pole-switched windings of various modifications.
Abstract
In the work, the switching circuits of the designed pole-switching windings are given for the 4АМ255М four-speed motor with the ratio of the numbers of poles 2p1:2p2:2p3:2p4=10:8:6:4. The results of studies of electromagnetic and electromechanical properties of motors with the proposed windings are presented.
