STATOR OF ROTATING ELECTRICAL MACHINE Russian patent published in 2017 - IPC H02K1/16 H02K3/32 H02K3/24 H02K15/12 

FIELD: electricity.

SUBSTANCE: starter of the rotating electrical machine includes a core, a multilayer coil winding, the first and the second insulating polymer layers. The multilayer coil winding is made with a predetermined number of sections in the radial direction of the tooth. Each section contains one turn of the lowest layer of the winding and another turn of the surface layer of the winding. The first insulating polymer layer is placed between the tooth and the winding of the lowest layer, or between the insulator that is attached to the tooth and the winding of the lowest layer. The second insulating polymer layer is located locally on the curved winding sections corresponding to the angular sections of the four corners of the rectangular cross section of the tooth. The second insulating polymer layer is executed lying through several winding sections.

EFFECT: increase the reliability and efficiency of cooling.
