DIPOLAR STATOR WINDING OF ASYNCHRONOUS GENERATOR Russian patent published in 2013 - IPC H02K17/14 H02K3/28 

FIELD: electrical engineering.

SUBSTANCE: dipolar stator winding of an asynchronous generator consists of twelve spool groups and excitation capacitors; the end of the first spool group is connected to the end of the seventh spool group, the beginning of the second one - to the beginning of the eighth one, the end of the third spool group - to the end of the ninth spool group, the beginning of the fourth spool group - to the beginning of the tenth spool group, the end of the eleventh spool group - to the end of the fifth spool group, the beginning of the twelfth spool group - to the beginning of the sixth spool group; the winding first output is taken from the conjoined end of the tenth spool group and beginning of the first one, the winding second output - from the conjoined beginning of the seventh spool group and end of the eighth one, the winding third output - from the conjoined end of the second spool group and beginning of the fifth one, the winding fourth output - from the conjoined beginning of the eleventh spool group and end of the twelfth one, the winding fifth output - from the conjoined end of the sixth spool group and beginning of the ninth one, the winding sixth output - from the conjoined beginning of the third spool group and end of the fourth one; the first, second and third excitation capacitors are connected to the winding first, third and fifth outputs.

EFFECT: enhanced energy efficiency of the asynchronous generator by way of reducing the level of losses in the stator winding through increase of the wire cross section in the high current winding part.
