ELECTRIC MACHINE Russian patent published in 2016 - IPC H02K1/27 H02K9/12 H02K7/09 H02K21/12 

FIELD: electronic equipment.

SUBSTANCE: electrical machine includes a housing which houses a laminated stator core with windings. Stator fixed inside the sleeve in which is placed a rotor comprising an inductor c poles, permanent magnets, nonmagnetic wedges and shaft. Housing is configured to supply coolant to the rotor and stator. Stator is configured to independent cooling. Sleeve is made of non-magnetic non-conductive material and is provided with a longitudinal protrusion hollow and has a rectangular strap slots, made of high-temperature superconducting material with a T-slot channels communicating with the radial holes to supply cold. In the housing coaxially with the stator core mounted cylindrical sleeve made in the form of a cup of insulating material, fastened by its ends to the outer ends of the stator core packets. Cylindrical sleeve formed on the sides of the end shields, used as angular contact holder passive magnetic bearings and a cylindrical cup formed at the outer ends of the rotor are used as they trunnion. Magnetic system of the inductor is made by the scheme Halbach.

EFFECT: increasing reliability.
