STATOR WINDING OF ASYNCHRONOUS GENERATOR FOR HEIGHTENED CURRENT FREQUENCY Russian patent published in 2008 - IPC H02K17/14 H02K3/28 

FIELD: electric engineering, possible use for building autonomous electric energy supplies, adapted for heightened current frequency.

SUBSTANCE: stator winding of asynchronous generator for heightened current frequency contains 18 coil groups with contacts from starts 1,7,13 of coil groups, where starts 3,9,15 of coil groups are combined in zero point, contacts are taken from combined ends 18 and 2 of coil groups, from combined ends 6 and 8 of coil groups, from combined ends 12 and 14 of coil groups, end 1 of coil group is connected to start 5 of coil group, end 5 is connected to start 10, end 10 is connected to start 14, start 12 is connected to end 3, end 7 is connected to start 11, end 11 is connected to start 16, end 16 is connected to start 2, start 18 is connected to start 9, end 13 is connected to start 17, end 17 is connected to start 4, end 4 is connected to start 8, start 6 of coil group is connected to end 15 of coil group, excitation capacitors C are connected to contacts 19,21,23 in accordance with required load power mode. Invention makes it possible to create autonomous energy supplies for heightened frequency and different voltages on basis of asynchronous generators with capacitor excitation.

EFFECT: improved external characteristic of asynchronous generator, ensured capacity for production of various output voltage at constant frequency of rotation of driving motor.
