STATOR WINDING OF DUAL-SPEED INDUCTION GENERATOR Russian patent published in 2005 - IPC

FIELD: electromechanical engineering; off-line power supplies built around capacitor-excited induction generators.

SUBSTANCE: proposed stator winding has 24 coil groups and field capacitors. Finishing lead of coil group 8i + 5 is connected to starting lead of coil group 8i + 8; finishing lead of coil group 8i + 8, to finishing lead of coil group 8i + 15; starting lead of coil group (8i + 15), to finishing lead of 8i + 18. Starting leads of coil groups 8i + 18 are interconnected at neutral point. Starting lead of coil group 8i - 7 is connected to finishing lead of coil group 8i - 4; starting lead of coil group 8i - 4, to starting lead of coil group 8i + 3, finishing lead of coil group 8i + 3, to starting lead of coil group 8i + 6. First phase leads are formed from finishing leads of coil groups 8i - 7, second phase leads, from interconnected starting lead of coil group 8i + 5 and finishing lead of coil group 8i + 6, where i = 1, 2, 3, number 24 being subtracted from that higher than 24. Windings are connected in star or in star-star whose leads are connected to field capacitors and load for different current frequencies. Such winding design makes it possible to produce off-line power supplies for different current frequencies and same voltage at fixed speed of drive motor.

EFFECT: enlarged functional capabilities.
