STATOR WINDING OF INDUCTION MACHINE Russian patent published in 2007 - IPC H02K17/04 H02K3/28 

FIELD: electrical engineering, applicable in production of independent high-frequency power sources, in particular-independent sources of high-frequency current energy on the basis of induction generators with a capacitor excitation.

SUBSTANCE: in the stator winding consisting of 18 coil groups, for improving the shape of the magneto motive force from the jointly flowing exciting and load currents, the end of the 1-st coil group is connected to the beginning of the 10 th coil group, the end of the 7 th coil group - to the beginning of the 16 th coil group, the end of the 13 th coil group to the beginning of the 14 th coil group, the beginning of the 2-nd coil group is connected to the end of the 11 th coil group, the beginning of the 6 th coil group is connected to the end of the 15 th coil group, the beginning of the 8 th coil group is connected to the end of the 17 th coil group, the beginning of the 12 th coil group is connected to the end of the 3 rd coil group, the beginning of the 14 th coil group is connected to the end of the 5 th coil group, the beginning of the 18 th coil group is connected to the end of the 9 th coil group, the ends of the 2 nd, 8 th, 14 th coil groups are combined to the zero point, the leads are taken from the combined beginnings of the 3 rd and 5 th coil groups, from the combined beginnings of the 9 th and 11 th coil groups, from the combined beginnings of the 15 th and 17 th coil groups, from the combined ends of the 4 th and 6 th coil groups, from the combined ends of the 10 th and 12 th coil groups, from the combined ends of the 16 th and 18 th coil groups.

EFFECT: improved external characteristics of the induction machine, in particular, induction generator due to differential dissipation at the load.
