FIELD: electrical engineering; multispeed motors. ^ SUBSTANCE: proposed winding is placed in 72 stator slots and has 12 similar coil groups which are cumulatively connected in each phase in following sequence: coil groups 1, 7, 10, 4 in first phase, 5, 11, 2, 8, in second phase, and 9, 3, 6, 12, in third phase, phase leads being connected in DeltaYY or Y/YY with six terminal leads of which three ones 8C1, 8C2, and 8C3 are designed for connection to supply mains at pole pair 2p = 8 and three other ones 4C1, 4C2, and 4C3, with 8C1, 8C2, and 8C3 interconnected in star, are designed for connection to supply mains at pole pair 2p = 4; coils in coil groups are placed in every other slot alternating as follows in stator inner bore: ABABABBCBCBCCACACAAB, etc. Use factor of active materials increases at 2p = 4. ^ EFFECT: reduced consumption of expensive materials and winding placement time. ^ 1 cl, 5 dwg |
