FIELD: electric machine engineering. SUBSTANCE: invention is meant for asynchronous and synchronous machines. Winding has numbers 1L+3k, 9L+3k, 17L+3 of coil groups in phases, coils are grouped into coil groups by row 3 2 2 2 2 2 2 2, groups with numbers 1L+8 have three coils with slots pitches 1 y= 7, 5, 3 and number of turns 2 Wk,1 Wk, 4 (1-x)Wkr, the rest of groups include two coils with 5 y=6 and 4 and number of turns 6 Wk, where k=0, 1, 2, . .., and 0.45 7 ≅ x ≅ 0.55. EFFECT: decreased differential dissipation and enhanced winding coefficient. 4 dwg
