DIPOLAR WINDING OF ASYNCHRONOUS GENERATOR Russian patent published in 2012 - IPC H02K17/14 H02K3/28 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering and may be used, in particular, in asynchronous generators with capacitor excitation for autonomous power plants. A dipole winding of an asynchronous generator is proposed, which comprises twelve coil groups with outputs and a certain logic of coil groups connection, in which the first output of the winding is taken from combined beginnings of the first, second and twelfth coil groups, the second output of the winding is taken from combined beginnings of the third, seventh and eleventh coil groups, the third output of the winding is taken from combined beginnings of the fourth, fifth and sixth coil groups, the fourth output of the winding is taken from the combined beginnings of the eighth, ninth and tenth coil groups, at the same time the end of the first coil group is connected with the end of the seventh coil group, the end of the second coil group is connected with the end of the eighth coil group, the end of the third coil group is connected with the end of the ninth coil group, the end of the fourth coil group is connected with the end of the tenth coil group, the end of the fifth coil group is connected with the end of the eleventh coil group, the end of the sixth coil group is connected with the end of the twelfth coil group, and the first, second and third capacitors of excitation are connected to the first, second and third outputs of the winding.

EFFECT: increased energy efficiency of an asynchronous generator by exclusion of action of higher spatial harmonics, at the same time appearance of a most expressed third time harmonic generated by a saturated magnetic conductor by inclusion of a part of winding into a delta is excluded.
