AUTONOMOUS INDUCTION GENERATOR WITH BIPOLAR STATOR WINDING Russian patent published in 2013 - IPC H02K17/14 H02K3/28 

FIELD: electricity.

SUBSTANCE: in the suggested autonomous asynchronous generator bipolar stator winding including twelve coil groups consists of a triangle scheme formed by the second and eighth, fourth and tenth, sixth and twelfth coils groups with the first, second and third outputs to which excitation capacitors are connected and star scheme formed by the first and seventh, third and tenth, fifth and eleventh coil groups with the fourth, Fifth, sixth and seventh outputs; at that the first output is taken from the beginning of united beginnings of the second and twelfth coil groups; the second output - from united beginnings of the fourth and sixth coil groups; the third output - from united beginnings of the eighth and tenth coil group; the fourth output - from beginning of the first coil group; the fifth output - from beginning of the fifth coil group; the sixth output - from united beginnings of the third, seventh and eleventh coil group; the seventh output - from beginning of the ninth coil group. The end of the first coil group is connected to the end of the seventh coil group; the end of the second coil group is connected to the end of the eighth one; end of the third coil group is connected to the end of the ninth one; end of the fourth coil group - with the end of the tenth one; end of the fifth coil group - with the end of eleventh one; end of the sixth coil group is connected to the end of the twelfth coil group; additionally, the first, second and third outputs of the triangle scheme and the fourth, fifth and seventh outputs of the star scheme are interconnected in pairs by compensation capacitors connected in-series and common points of these capacitors connection have outputs to connect load to the generator.

EFFECT: providing back induction compensation for inductive components of load and rotor currents by means of winding manufacturing as two parts thus increasing energy efficiency of autonomous asynchronous generator.
