Keywords:
phase zones, number of stator grooves, winding scheme, parallel branches, equalizing EMF.
Abstract
Using the tabular-vector method, schemes of two-speed pole-switched windings (PSW) with a pole ratio of 2р1:2р2=6:4 were designed in 36 slots of the stator with high values of winding coefficients on both numbers of poles with subsequent symmetrization and a zero value of the differential EMF when the winding is turned on at 2р2 =4.
The switching schemes and the scanning scheme of a single-double-layer PPO with the ratio of poles 2r1:2r2=6:4 and the UUU/UUU switching scheme are given.
