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 (q=32/13 and q=33/13). The invention novelty consists in the following. The winding at 2p=26c poles made up of 3pc coil groups with the numbers from 1"" to 39""c is configured as follows, i.e. 1) in z=96 c slots with the number of slots per a phase and pole q=32/13 and the coil group in the series 3232323232322, the first group 1""...13"" has the three-coil groups with coil pitch over slots ysi= 6, 4, 2 with the number of turns (1-x) wc, wc, (1-x) wc in 1"", 11"" and (1-x) wc, (1+x)wc, (1-x)wc in 3"", 5"", 7"", 9"", while the two-coil windings have y'si=5, 3 with wc, (1+x) wc turns at x=0.44, 2) in z=99c slots with the number of slots per a phase or pole q=33/13 and the coil group in the series 3323232323232, i.e. in the first group 1""...13"", the three-coil windings feature the coil pitch over the slots ysi= 6, 4, 2 with the number of turns (1-x) wc, (1+x) wc, (1-x) wc turns and the two-coil windings feature y'si=5, 3 with wc, (1+x)wc turns at x=0.55. 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 |
