FRACTIONAL-SLOT THREE-PHASE STATOR WINDING Russian patent published in 1995 - IPC

Abstract RU 2046500 C1

FIELD: electrical machines. SUBSTANCE: inner and outer coils of each even-numbered group of stator winding have (1+x)·W_c and (1-x)·W_c, and turns, respectively; groups of each phase are series-connected; even-numbered groups are differentially connected relative to odd-numbered groups, where p 1, 2, 3, k 0, 1, 2.(2p-1); 2·W_c is number of turns per slot; x value is chosen from 0,45≅ x≅ 0,50 range. EFFECT: improved design. 5 dwg
