摘要：

Abstract: We discuss a combined winding of an alternating current machine with one set of leads, which, due to the pole-amplitude modulation of the magnetomotive force in the air gap, creates two harmonics of different poles, rotating opposite to each other. The design principles of such a winding are described, and expressions for the number of turns of the phase, the magnetomotive force, and the relation for the distribution of conductors along the slots are obtained. Spatial patterns of counter-rotating harmonics of magnetomotive force with five and three pairs of poles are demonstrated. The practical implementation of such a winding in synchronous motors operating in frequency-controlled electric drives is considered. © 2023, Allerton Press, Inc.
