ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K21/22 H02K1/27 H02K5/04 H02K7/09 

FIELD: electricity.

SUBSTANCE: electrical machine comprises imbricated core of the stator, at which cylindrical surface there are slots with winding coils placed inside them. The stator core is mounted at support housing and is fixed rigidly to it. The stator support housing is made as a cylindrical barrel with sidewall mid part provided with cylindrical ledge. Stator is arranged inside cylindrical cavity of the rotor. The rotor comprises inductor based on permanent magnets. Rotor body is made as two detached discs fixed by their edges and faced to each other with their cavities. Inductor is mounted at peripheral area of the rotor housing and is comprised of permanent magnets shaped as trapezoidal bars oriented along the rotor longitudinal axis thus forming a composite magnet ring with creation of Halbach array. A bearing unit of the electrical machine includes radial and thrust magnetic bearings. Radial magnetic bearings are represented by composite permanent magnets magnetised so that they create Halbach array. Composite permanent magnets form thrust magnetic bearings.

EFFECT: increased resource of the electrical machine, increased circumferential speed of the inductor, reduced friction in bearings.
