FIELD: electrical engineering.
SUBSTANCE: proposed three-phase pole-changing winding has differentially connected coil groups. Each phase includes six cumulatively connected parts. First part incorporating coil groups numbered 8i - 7, 8i - 4, 8i - 1, and 81 + 2 is connected to second part of coil groups numbered 8i + 17, 8i + 20, 8i + 223, and 8i + 26. Second part is connected to third part of coil groups numbered 8i + 41, 8i + 44, 8i + 47, and 8i + 50. Third part is connected to fourth part of coil groups numbered 8i + 5, 8i + 8, 8i + 11, and 8i + 14. Fourth part is connected to fifth part of coil groups numbered 8i + 29, 8i + 32, 8i + 35, and 8i + 38. Fifth part is connected to sixth part of coil groups numbered 8i + 53, 8i + 56, 8i + 59, and 8i + 62. Terminal leads are brought out from starting leads of coil groups 8i - 7 and 8i + 50 and finishing leads of coil group 8i + 62 form neutral point (i = 1, 2, 3).
EFFECT: enlarged functional capabilities at increased number of stator slots.
