ELECTRIC MACHINE Russian patent published in 2018 - IPC H02K21/22 H02K7/14 H02K1/27 

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment. Electric machine contains a laminated stator core with grooves on the outside, in which coils of the winding are laid. Coaxially rotor with the possibility of rotation with respect to it is placed an intermediate rotor, in the cylindrical cavity of which the gap is fitted with a stator. Rotor is made in the form of a disk coaxial to the cylindrical shaft, along the periphery of which a cylindrical shell is made parallel to the surface of a cylindrical shaft on which the rolling bearings are attached and fixed from the longitudinal movement. They are supported by a cylindrical part of the body of the electric machine, one end of which is provided with a flat ring, the outer part of which is made with an outer and inner ring protrusions. On the outer surface of the cylindrical part of the body is mounted a laminated stator core with a winding. On the opposite end of the cylindrical part of the body, the end shield of the casing is put on and locked into the stator core by its inner ring protrusion, the outer edge of which is formed with a second annular shoulder on which the rolling bearings are put on and on the inner annular projection of the housing. They also support a cylindrical non-magnetic bushing of the intermediate rotor on the inner surface of which the magnetic system is mounted. On the inner surface of the cylindrical shell of the rotor is fixed its laminated core, in the cylindrical cavity of which is mounted a magnetic system, in the cylindrical cavity of which the poles of magnetic transmission from a material with a high magnetic permeability are placed with a gap, alternating with nonmagnetic inserts. Both of these magnetic systems are magnetized, for example, according to the Halbach scheme. Ends of the said elements are rigidly attached to the surface of the outer annular body projection facing them.

EFFECT: technical result consists in increasing the speed of rotation and the resource due to the absence of a mechanical transmission, as well as providing the possibility of using the outer surface of the rotor as a hub of an electric vehicle, a hydro generator rotor or a wind generator.
