ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K21/22 H02K1/27 H02K5/04 H02K5/16 

FIELD: electricity.

SUBSTANCE: electrical machine comprises stator support housing, imbricated stator core of electrical steel with slots at its outer cylindrical surface with winding coils placed into the above grooves and fixed with slot wedges. Support housing is made as a cylindrical barrel with sidewall mid part provided with cylindrical ledge. Stator is placed inside cylindrical cavity of the rotor, which is mounted coaxially with stator cylindrical axis and can be rotated around it. Rotor body is made as two detached discs fixed by their edges and faced to each other with their cavities. Rotor comprises inductor coil. Inductor coil is comprised of magnet bar oriented along the rotor longitudinal axis magnetised in tangential opposite direction alternated with poles made as bars of material with high magnetic conductivity. Areas of the discs placed close to the rotor longitudinal axis are have bending made so that it can fix the outer bearing race, which inner race is installed at the area of support housing opposite the inner bearing race.

EFFECT: simplified design, increased peripheral rate of inductor.
