STATOR AND METHOD OF ITS ASSEMBLY Russian patent published in 2012 - IPC H02K1/16 H02K3/14 H02K15/85 

Abstract RU 2448403 C2

FIELD: electricity.

SUBSTANCE: assembled stator comprises a stator core having the first end, the second end and multiple slots passing from the first end to the second end; multiple current-carrying cords comprising many separate insulated wires. Besides, at least one section of multiple current-carrying cords passes from the first end to the second end of one slot from the specified multitude of slots, at the same time the specified at least one section is twisted inside the specified one slot by the previously determined value to reduce the current circulating along the multitude of separate insulated wires on the specified at least one section to the minimum, and multiple current-carrying cords contain multiple pairs of current-carrying cords connected with a double star, besides, each pair of current-carrying cords corresponds to an AC phase connected to a stator, and has at least two current-carrying cords connected in parallel. Also the method to assemble such stator is proposed.

EFFECT: reduction of current circulating along multiple separate insulated wires on the section of each current-carrying cord arranged in a slot of a stator core to the minimum.
