Zusammenfassung:An operating mechanism for operating an actuating member is provided with an electric motor (11, 12), a resetting spring (3) and a centrifugal brake (20), wherein the actuating member can be operated in a first direction of movement by the electric motor (11, 12) activated by means of a control or regulating device, and in a second direction of movement by means of the resetting spring (3). In accordance with the invention, a brake body (22) of the centrifugal brake (20) is arranged on the rotor (12) of the electric motor (11, 12). The centrifugal brake (20) arranged directly on the rotor (12) can be configured such that a braking effect is generated only when the actuating member is operated by the resetting spring (3). When operated by the switched-on electric motor (11, 12), on the other hand, the centrifugal brake (20) has no braking effect. By means of the centrifugal brake (20) the speeds that can be reached are limited to the extent that no spurious vibrations and noises occur.
