BEARINGLESS ELECTRIC MOTOR Russian patent published in 2018 - IPC H02K7/08 H02K16/04 H02K1/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in various installations with a high-speed electrical drive of the working member, in particular, under vacuum conditions. Bearingless electric motor contains a hollow rotor with external and internal ferromagnetic parts, external and internal stators of radial suspension and rotation, as well as two end stators installed relative to the disk of the axial centering of the rotor, in which toroidal twisted magnetic circuits with windings connected to electronic control units and to two-phase or three-phase power network are used.

EFFECT: technical result consists in simplifying the manufacture, increasing the axial and angular stiffnesses and overload capacities, creating an additional torque while maintaining the engine's volume.
