ELECTRIC DRIVE Russian patent published in 2016 - IPC H02K7/10 F16D27/01 

FIELD: machine building.

SUBSTANCE: invention can be used in designs of drives transmitting torque from motor to actuator. Electric drive comprises drive motor, consisting of stator and rotor with magnets on its outer surface, as well as magnetic coupling and tight screen dividing coupling into half-couplings with permanent magnets mounted thereon. Motor rotor is made hollow from nonmagnetic material, and in its cavity through sealed screen there is a half-coupling of magnetic coupling. Permanent magnets on outer surface of rotor are made in form of separate segments and can form a mosaic structure. On surface segment magnets facing electric motor stator, can be installed a bandage made from high-strength non-magnetic material, for example stainless steel.

EFFECT: simplified design.
