Shift of the modulation wave in the construction of two-speed windings by the method of pole-amplitude modulation.

Abstract

The method of modulation wave shift is considered for obtaining additional variants of the distribution of sections in the phase zones of two-speed windings constructed by the pole-amplitude modulation method. The conditions for the equivalence of the numerical series of windings are given. A technique has been developed for determining the number of shifts of the modulation wave necessary for obtaining all possible original numerical series of windings. A formula for determining the amount of shift at each step is derived. Tab. 2, ill. 3, Bible. 4.
