DOUBLE-LAYER STATOR WINDING OF DOUBLE-POLE INDUCTION GENERATOR Russian patent published in 2005 - IPC

FIELD: electrical engineering; dual-voltage off-line power supplies built around capacitor-excited generators at constant speed of drive motor.

SUBSTANCE: proposed double-layer stator winding has 12 coil groups; novelty is that finishing lead of coil group 1 is connected to that of coil group 8, starting lead of coil group 7, to that of coil group 2, finishing lead of coil group 5, to that of coil group 12, starting lead of coil group 11, to that of coil group 6, finishing lead of coil group 9, to that of coil group 4, starting lead of coil group 3, to that of coil group 10; phase leads are brought out from interconnected starting lead of coil group 1 and finishing lead of coil group 6, from interconnected starting lead of coil group 5 and finishing lead of coil group 10, from interconnected starting lead of coil group 9 and finishing lead of coil group 2, from interconnected starting lead of coil group 4 and finishing lead of coil group 3, from interconnected starting lead of coil group 8 and finishing lead of coil group 7, from interconnected starting lead of coil group 12 and finishing lead of coil group 11; field capacitors are connected to respective winding leads in compliance with generator output voltage.

EFFECT: enlarged functional capabilities of generator affording two voltages at constant speed of drive motor.
