FIELD: electrical engineering; variable-speed induction motors. ^ SUBSTANCE: proposed pole-changing stator winding has 18 coil groups with starting leads of coil groups 1, 3, 7, 9, 13, 15 and integrated starting leads of coil groups 5, 11, 17. Finishing lead of coil group 1 is connected to that of coil group 10, finishing lead of coil group 3, to that of coil group 12, finishing lead of coil group 5, to that of coil group 14, finishing lead of coil group 7, to that of coil group 16, finishing lead of coil group 9, to that of coil group 18, finishing lead of coil group 11, to that of coil group 2, finishing lead of coil group 13, to that of coil group 4, finishing lead of coil group 15, to that of coil group 6, finishing lead of coil group 17, to that of coil group 8; starting leads of coil groups 4, 6, 5, those of coil groups 10, 12, 14, and starting leads of coil groups 16, 18, 2 are integrated. ^ EFFECT: ability of developing three-speed induction motors with reduced number of stator winding leads. ^ 1 cl, 5 dwg |
