AUTONOMOUS INDUCTION GENERATOR WITH AUTOTRANSFORMER STATOR WINDING Russian patent published in 2018 - IPC H02K17/42 H02K17/12 

FIELD: electricity.

SUBSTANCE: generator comprises an autotransformer stator winding consisting of twelve coil groups with leads. The first three leads are interconnected and taken from the ends of the third, fifth and seventh coil groups. The second three leads are taken from the combined beginnings of the ninth and the end of the eighth coil groups, from the combined beginning of the eleventh and the end of the tenth coil groups, from the combined beginnings of the first and the end of the twelfth coil groups, respectively. Three third leads are taken from the beginnings of the second, fourth and sixth coil groups. The end of the second coil group is connected to the beginning of the eighth coil group, the end of the ninth with the beginning of the third, the end of the fourth with the beginning of the tenth, the end of the eleventh with the beginning of the fifth, the end of the sixth with the beginning of the twelfth, the end of the first coil group is connected to the beginning of the seventh coil group. The excitation capacitors are connected to the third leads of the generator, and the load - to the second three-phase leads.

EFFECT: reduction of electrical losses.
