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: devices for electromechanical power conversion. The device is a magnetic system of a three-phase synchronous electric machine with permanent magnets (2), a rotor (1), which can be located both outside the stator (3) and inside it. The stator (3) contains a distributed three-phase winding, the coils of which can be placed in slots 2, 4, 8, etc. of layers. The groove (4) of the stator (2) is open. The stator winding coils are made in such a way that the frontal parts have a rigid shape, and the working sections remain flexible and capable of deformation sufficient to ensure that the coil is immersed in the stator grooves without damaging the wire insulation layer.

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.
