Magnetomotive Forces of Three-Phase Windings of Asynchronous Machines

摘要

Space-time waves of magnetomotive force (mmf) for three-phase windings of asynchronous machines taking winding distribution by slots, width, and angularity of slots into account are constructed. Additional variations of an mmf wave of sixfold frequency are revealed. The maximums for one- and two-layer windings are plotted.
