FIELD: electrical engineering; variable-speed induction motors.
SUBSTANCE: winding whose rated pole number is 2p = 10 has similar coil groups with alternately differentially and cumulatively connected coil groups numbered 4i - 3, 4i - 2, 4i + 3, 4i + 4; finishing lead of coil group 4i - 3 is connected to starting lead of coil group 4i + 4; finishing lead of coil group 4i + 4 is connected to starting lead of coil group 4i + 3; finishing lead of coil group 4i + 3 is connected to starting lead of coil group 4i - 2; finishing leads of coil groups 4i - 2 are integrated into neutral point, taps are branched off starting leads of 4i - 3 and off starting leads of 4i + 3 coil groups (i = 1, 2, 3 and 12 is subtracted from numbers higher than 12).
EFFECT: enhanced winding coefficient at rated pole number.
