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=54/13 and q=56/13). For this, the aforesaid winding at 2p=26c poles is composed of 3pc coils groups with the numbers 1""...39""c, i.e. 1) in z=162c slots with the number of slots per a pole and phase q=54/13 and the group 5444445444444, i.e. the first group 1""...13"" the five-coil groups feature the coil pitch along the slots ysi=10, 8, 6, 4, 2 with (1-x)wc, wc, wc, wc, (1-x)wc turns, while the four-coil groups feature y'si=9, 7, 5, 3 with wc, (l+x)wc, wc, (1-x)wc turns in 4"", 10"", 11"", y's=6 with wc, (1+x)wc, wc, (1-x)wc in 2"", 3"", 8"", 9"" and (1-x)wc, wc, (1+x)wc, wc in 5"", 6"", 12"", 13"" at x=0.46, 2) in z=168c slots with the number of slots per a pole and phase q=56/13 and the coil group 5445445445444, i.e. in the first group 1""...13"", the five-coil groups feature the coil pitch over the slots ysi=10, 8, 6, 4, 2 with (1-x)wc, wc, wc, wc, (1-x)wc turns, while the four-coil feature y'si=9, 7, 5, 3 with wc, (1+x)wc, wc, wc turns in 2"", 3"", 5"", 6"", 8"", 9"" and wc, (1+x)wc, wc, (1-x)wc in 12"", y's=6 with wc, (1+x)wc, wc, wc in 11"" and wc, wc, (1+x)wc, wc in 13"" at x=0.37. 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 slot turns filled completely with the winding. ^ EFFECT: reducing winding differential dissipation factor. ^ 2 cl, 8 dwg |
