TWO-LAYER STATOR WINDING OF BIPOLAR ASYNCHRONOUS MACHINE Russian patent published in 2007 - IPC H02K17/14 H02K3/28 

FIELD: electric engineering, possible use in autonomous energy sources with increased operational characteristics based on asynchronous generators with capacitor excitation.

SUBSTANCE: two-layered stator winding of bipolar asynchronous machine consists of 18 coil groups with clamps 19, 20, 21, 22, 23, 24 from combined start 1 and end 8 of coil groups, from combined start 7 and end 14 of coil groups, combined start 13 and end 2 of coil groups, from combined end 5 and start 6 of coil groups, from combined end 11 and start 12 of coil groups, from combined end 17 and start 18 of coil groups, where end 1 of coil group is connected to start 3 of coil group, end 3 is connected to end 10, start 10 is connected to end 12, start 11 is connected to start 2, end 13 is connected to start 15, end 15 is connected to end 4, start 4 is connected to end 6, start 5 is connected to start 14, end 7 is connected to start 9, end 9 is connected to end 16, start 16 is connected to end 18, start 17 is connected to start 8 of coil group, and excitation capacitors C are connected to clamps 19, 21, 23.

EFFECT: improved operational characteristics of generator due to reduction of differential dissipation of winding of its stator.
