DISK ASYNCHRONOUS ELECTRIC MACHINE Russian patent published in 2025 - IPC H02K17/16 H02K16/04 

FIELD: electrical engineering.

SUBSTANCE: in disc asynchronous electric machine ferromagnetic stator contains two identical flat rings, two groups of rods, and two groups of multiphase concentrated winding located on rods. Each of the rods by one end is attached to one end surface of its ring, and other ends of all rods are made with pole tips. Rotor is made in the form of a disc with a flat ferromagnetic ring fixed on it along the perimeter, the outer and inner diameters of which are equal to the outer and inner diameters of the stator rings. In the central part of the rotor there is a shaft resting on bearings with another ring pressed on it and connected by means of stiffeners with a flat ferromagnetic rotor ring. On the end surfaces of the rotor ring there are radial slots and teeth; in the slots there are rotor winding conductors closed into individual rings. Identical air gaps are made between rotor teeth and pole tips of stator rods on both sides.

EFFECT: improved cooling of the stator winding and balancing of electromagnetic forces acting on the rotor in the axial direction.
