COMPOSITE SIX/FOUR-POLE WINDING Russian patent published in 2003 - IPC

FIELD: electrical engineering; electrical machines and rotary frequency changers. SUBSTANCE: composite six/four-pole winding has twelve coil groups with equal number of coils Z₂/4 in each group, where Z₂ is number of rotor slots, with terminal leads running from interconnected starts of coil groups 2, 6, 10, from interconnected finishes of coil groups 3, 7, 11, from finishes of coil groups 1, 5, 9 interconnected with starts of coil groups 4, 8, 12; in this case starts of coil groups 1, 3, 5, 7, 9. 11 are interconnected and so are finishes of coil groups 2, 4, 6, 8, 10, 12. Proposed design makes it possible to use this winding as composite rotor winding for rotary converters. EFFECT: enlarged functional capabilities. 1 cl, 2 dwg
