Abstract: Disclosed is an actuator for the rotary drive of a vehicle flap. The actuator includes an electric motor, which has a output shaft with a center axis, an output unit, which is in force-transmitting connection with the electric motor in such a manner that activation of the electric motor causes a rotational displacement of the output unit about an axis of rotation of the output unit, and a mounting unit which is configured to support the actuator in force-transmitting connection with a superordinate assembly relative to the drive unit such that, upon activation of the electric motor, a displacement of the drive unit relative to the mounting unit takes place. Also disclosed is a storage apparatus for a vehicle door and a motor vehicle.

Abstract: An electric side door drive assembly for a vehicle having a length-adjustable electric actuator to bring about opening and closing of the side door, and a door movement sensor unit designed to detect stopping and a current position of the side door during opening or closing of the side door. In the event of stopping of the side door detected by the door movement sensor unit, a controller determines, on the basis of side door position data provided by the door movement sensor unit, a necessary current strength which is to be supplied to the electric motor to hold the side door in its current position, and to deliver the necessary current strength to the motor of the actuator for a holding operation.

Abstract: Provided is a brake device for braking a rotational movement of a shaft about the longitudinal axis, wherein the shaft is mounted so as to be rotatable about the longitudinal axis in a direction of rotation and in a counter direction which opposes the direction of rotation. Brake devices typically use constant and relatively high braking torques, to ensure a controlled movement of a movement portion, braked by the brake device, in every situation. However, this increases the energy consumption for a movement of the movement portion, and the wear of the brake device. A brake device equipped with a setting device for mutually opposing setting of a braking torque on the shaft during rotation of the shaft in the direction of rotation, and a counter braking torque during rotation of the shaft in the counter direction is provided. Also provided is a method for controlling a brake device.
