COMBINED 3/1 PHASE WINDING Russian patent published in 1997 - IPC

FIELD: electric machines. SUBSTANCE: device has p₁/p₂ pole pairs in z slots of k = 24 coil groups which period is z/8-1. Winding is connected to parallel three-phase star circuits which have terminals A, B, C at their inputs for pole number p1=4 and terminals 01-02 for zero points of star for pole number p2=6. In first phase input terminals of groups 1, 7, 13, 19 in and output terminals of groups 4, 10, 16, 22 are connected to terminal A, output terminals of groups 1, 13 and input terminals of groups 4, 16 are connected to terminal 01, output terminals of groups 7, 19 and input terminals of groups 10, 22 are connected to terminal 02. In other phases serial numbers of groups go in alternating order with respect to groups of phase A in intervals of four groups for phase B and in eight for phase C. Z/24 is integer. EFFECT: increased field of application, increased functional capabilities. 3 dwg
