AUTONOMOUS INDUCTION GENERATOR WITH QUADRIPOLE STATOR WINDING Russian patent published in 2013 - IPC H02K17/42 H02K17/14 

FIELD: electricity.

SUBSTANCE: in an autonomous induction generator a quadripole stator winding is made of 12 coil groups (1-12) and excitation capacitors. The winding of the asynchronous generator in each phase is formed from coil groups (1, 3, 5, 7, 9, 11) in the form of the first dual-beam "star" with outputs (13, 14, 15, 19), to which the excitation capacitors are attached, and the second dual-beam "star" with outputs (13, 16, 17, 18), which are formed by connection of coil groups (2, 4, 6, 8, 10, 12). The output (13) is taken from combined ends (1, 3, 5, 7, 9, 11), connected with starts (2, 4, 6, 8, 10, 12) of coil groups; the output 14 - from combined starts (1,7) of coil groups; the output (15) - from combined starts (3, 9) of coil groups; the output (16) - from combined ends (4,10) of coil groups; the output (17) - from combined ends (6, 12) of coil groups; the output (18) - from combined ends (2, 8) of coil groups; the output (19) - from combined starts (5, 11) of coil groups. Additionally outputs (14, 15, 19) at one side and outputs (16, 17, 18) at the other side are connected to each other by pairs of serially connected compensation capacitors, and general points of connection of these capacitors have outputs for connection of the load to the induction generator.

EFFECT: higher energy efficiency of an induction generator.
