FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electrical engineering and aims at reducing differential dissipation factor sigmad of the electric machine symmetric divided loop with m'=3-section furnished with (q=52/11 and q=53/11). The invention novelty consists in that the winding at 2p=22with poles is made up of 3pc coil groups with the numbers 1""...33""c, i.e. 1) in z=156c slots with the number of slots per a pole and phase q=52/11 and the coil group 55545554554, i.e. in the first group 1""...11"" the coils feature the pitch over the slots ysi=11, 9, 7, 5, 3 with (1-x)wc, wc, (1+x)wc, wc, (1-x)wc turns, while the four-coil windings feature y'si=10, 8, 6, 4 with wc, (1+x)wc, (1+x)wc, wc turns at x=0.41, 2) in z=159c slots with the number of slots per a phase and pole q=53/11 and the coil group 55555455554: in the first group 1""...11"" feature the pitch over the slots ysi=11, 9, 7, 5, 3 c wc, wc, wc, wc, (1-x)wc turns 1"", 5"", 7"", 10"" and wc, wc, (1+x)wc, wc, (1-x)wc in 3"", ys=7 with (1-x)wc, wc, (1+x)wc, wc, wc in 2"", 8"" wc, wc, (1+x)wc, wc, (1-x)wc, in 4"", 9"" and y'si=10, 8, 6, 4 with wc, (1+x)wc, (1+x)wc, wc turns in 6"", 11"" at x=0.52. The aforesaid distributions of coils with unequal number of turns are repeated in every following group, where c=1, 2, 3...; 2wc is a number of slots filled completely with the winding. ^ EFFECT: reducing winding differential dissipation factor. ^ 2 cl, 8 dwg |
