ARRESTER OF STEERING ELECTRIC GEAR OF ROCKET Russian patent published in 2011 - IPC G01C19/26 G01B3/02 G01D11/20 B64G1/66 

FIELD: machine building.

SUBSTANCE: arrester consists of stationary part with coils, of movable part and of holder of shaft of electric drive kinematically connected with movable part. The stationary part is made in form of a hollow stator with two poles and two coils on the poles and equipped with two permanent magnets. The movable part is made in form of a limited rotary dynamically balanced rotor installed in a cavity of the stator on an axle; the rotor is kinematically connected with the holder for fixation or release of the shaft of the steering electric drive at direct or reverse turn of the rotor at feed of a current pulse to one or another coil. The stator is equipped with two stops for restriction of rotor turns and for facilitation of magnetic gap between the rotor and permanent magnets oriented along rotor axis mainly parallel to two facets of the rotor side adjacent to them and located on a coils side.

EFFECT: reduced dimensions of arresting device for electric drive of rocket.
