SINGLE-PHASE POLE-CHANGING MOTOR WINDING Russian patent published in 1998 - IPC

Abstract RU 2101833 C1

FIELD: electrical engineering. SUBSTANCE: split-phase winding with pole-pair ratio P₁:P₂= 1:2 has two coil groups, diametral winding pitch for pole pair P₂; pole pair P₁ is formed by differential connection of coil groups of first and second parts of winding and pole pair P₂, by their cumulative connection. EFFECT: facilitated manufacture and reduced input of active materials. 4 cl, 5 wdgf
