MAGNETIC SYSTEM OF AN ELECTRIC MACHINE WITH A MULTILAYER ULTRA-COMPACT WINDING Russian patent published in 2023 - IPC H02K3/12 H02K15/06 

FIELD: electrical engineering.

SUBSTANCE: stator coil comprises frontal parts and working areas. A feature of the invention is the implementation of the frontal parts of a rigid shape, and the working section is flexible and capable of deformation sufficient to ensure that the coil is immersed in the stator grooves without damaging the insulating layer of the wire. Another feature is the execution of the section of the coil in the working section located inside the stator groove, having the shape of a rectangle and equal to the section of the coil in the frontal part, located outside the stator package, so that the height of the rectangular section in the working section of the coil is equal to the width of the rectangular section in the frontal part coils, and the width of the rectangular section in the working section of the coil is equal to the height of the rectangular section in the frontal part of the coil.

EFFECT: increase in power efficiency, specific characteristics, as well as a simplification of production process and an increase in the reliability and durability of electrical machines.
