ELECTRIC MACHINE Russian patent published in 2017 - IPC H02K1/27 H02K9/12 H02K7/09 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the electric machine building. The electric machine comprises a rotor on which inductor is fixed with a cylindrical outer surface made in the form of a cylindrical shaft of a nonmagnetic material having a longitudinal radial cavities for placement of magnetic strips. The cavities are made as through channels without communication with the outer surface of the rotor, wherein the channel surface sections facing it and a rotor rotation axis are made with rounding, whose radius of curvature is smaller than the radius of curvature of the outer surface of the rotor. Magnetic strips sections facing the outer surface of the rotor are congruent to the surface of channels, and their opposing sections are flattened. Magnetic strips are magnetized radially. Housing cavity is configured to enable coolant supply to the rotor and stator, and the drainage of the latter after heating in the machine, and the stator is configured to enable independent cooling. Electric machine comprises passive magnetic bearings magnetized under the Halbach scheme.

EFFECT: reduction in weight and size of the electric machine, improving its reliability and efficiency of the cooling the stator winding and core.
