COMBINED ELECTRICAL-MACHINE WINDING Russian patent published in 1995 - IPC

FIELD: electromechanical engineering; rotary converters. SUBSTANCE: combined electrical-machine winding has pole pairs p₁/p₂= 8/6 of K=24 coil groups. Winding is placed in slots with pitch y_n= Z/16. Is connected into three-phase parallel stars. Winding has three-phase leads A,B,C brought out from their starts for pole pair p₁, additional leads 01-02 from their neutral points of stars for pole pair p₂. In first phase, starting leads of groups 1,4,7,10,13,16,19,22 are connected to lead A, finishing leads of groups 4,7,16,12, to lead 02. Groups of other phases are alternating in respect to phase A. For phase B, alternating interval is 4 and for phase C it is 8. EFFECT: improved design. 3 dwg
