Two-phase three-phase windings with odd numbers of grooves on the pole and phase.

Abstract

The method of structural design synthesized two subsets of two-coordinate three-phase windings with odd numbers of grooves on the pole and phase. A general for both subsets is an analytical expression for calculating windings of coefficients by arbitrary harmonics. The regulation properties of the proposed windings are investigated and the possibility of quenching harmonics of given orders is shown.
