Patent ID: 8618705

Claim:
An electromechanical device for at least one of driving and braking a shaft ( 1 ), the electromechanical device comprising: an electric motor having a rotor ( 2 ) that is fixedly connected to the shaft ( 1 ), and a stator ( 4 ) being supported in a housing ( 3 ) around the shaft ( 1 ) with a rotational degree of freedom in a peripheral direction in a direction of brake actuation, the stator ( 4 ) being operatively connected to the brake pad ( 7 ) by a device ( 5 ) that converts rotational movement of the stator ( 4 ) into axial movement of at least one brake pad ( 7 ) that is supported in an axially movable fashion such that, when the electric motor is operated as a generator, the stator ( 4 ) is rotated relative to the housing ( 3 ) by torque arising between the rotor ( 2 ) and the stator ( 4 ), the brake pad ( 7 ) is biased by the device ( 5 ) against the brake disc ( 8 ).
