STATOR FOR ELECTRIC MACHINE, ELECTRIC MACHINE AND THE MANUFACTURING METHOD Russian patent published in 2019 - IPC H02K3/14 H02K3/28 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment, in particular to the electrical machine stator. Stator contains plurality of slots with the corresponding slot bottom and having at least one first bundle winding. First bundle is associated with predetermined number of the first slots from the stator’s plurality of slots. At least one section of the first bundle winding is inserted into each of the first slots. First bundle has plurality of electrically in-parallel connected individual wires, which are made as the round wire, and in each of the winding sections at least some of the individual wires are arranged one above the other in the stator radial direction. At that, the winding sections are located in the first slots in such a way that for all individual wires the individual wires to the slot bottom average radial distance (m) is the same. First bundle has at least two electrically parallel branches, in each of which there is the twisting area, in which, after the first coil winding during movement to the next connected thereto coil, individual wires inside the winding are turned for 180°.

EFFECT: higher reliability.
