FIELD: electrical engineering. ^ SUBSTANCE: winding incorporates 2p=16c poles made up of 3pc coil groups with the numbers from 1"" to 24""c in z=3(8b+5)c=63c slots, or in z=87c, or in z=111c slots at b = 2, 3, 4 and with the number of the slots per a pole and phase q=z/3p=21/8, or q=29/8, or q=37/8. In compliance with the first version, the winding is made in z=63c slots with q=21/8 and the coil group 3 3 2 3 3 2 3 2 in the series repeated 3c times. Note, that in the first group 3""...8"", the three-coil windings feature the coil pitch over the slots ysi=6, 4, 2 and are made with (1-x)wc, (1+x)wc, (1-x)wc turns while the two-coil groups feature the coil pitch over the slots y'si=5, 3 are furnished with wc, (1+x)wc turns at x=0.56. In compliance with the second version, the winding is laid in z=87c slots with q = 29/8 and the coil group 4 4 3 4 4 3 4 3 in the series repeated 3c times. Note that in the first group 1""...8"", the four-coil windings feature the coil pitch over the slots ysi=8, 6, 4, 2 and are made with (1-x)wc, (1+x)wc, wc, (1-x)wc turns while the three-coil windings feature the coil pitch over the slots y'si=7, 5, 3 are made with wc, (1+x)wc, wc turns at x = 0.58. In compliance with the third version, the winding is made in z=111c slots with q = 37/8 and the coil group 5 5 4 5 5 4 5 4 in the series repeated 3c times. Note that in the first group 1""...8"", the five-coil windings feature the coil pitch over the slots ysi=11, 9, 7, 5, 3 and are made with (1-x)wc, wc, (1+x)wc, wc, (1-x)wc turns, while the four-coil groups feature the coil pitch y'si = 10, 8, 6, 4 and are made with wc, wc, (1+x)wc, wc turns at x = 0.57. 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. ^ 4 cl, 10 dwg |
