Electromechanical arrangement for driving and/or braking a shaft

Abstract

An electromechanical device for driving and/or braking a shaft (1) includes an electric motor having a rotor (2) that is rotationally fixed to the shaft (1), and a stator (4) supported in a housing (3) around the shaft (1) with a rotational degree of freedom in the peripheral direction in the direction of brake actuation. The stator (4) is 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), such that the brake pad (7) is pressed by the device (5) against the brake disc (8).
