The present invention relates to an electrical machine having a rotor, a stator, and a permanent magnet located on the rotor. The permanent magnet is embodied essentially as a hollow cylinder with axial and/or radial contact faces and is secured to the rotor at the axial and/or radial contact faces by means of retaining elements; the permanent magnet is elastically supported in the axial direction (X-X) and/or the radial direction of the rotor by means of the retaining elements.

Electric machine comprising a permanent magnet

The invention is based on a control drive for operating drive components or adjusting components in motor vehicles. The control drive comprises an electric actuator () that acts on force-transmitting elements (). With these, the adjusting motion is transmitted to the drive or adjusting components to be adjusted. A throwout element () is provided that interrupts the transmission of force by the force-transmitting elements () in the de-energized state () of the electric actuator.

Method and device for decoupling an actuator from a gear

The invention is based on a device for actuating a clutch ( ), in particular for motor-vehicle drives, having an electronically controllable clutch servo unit ( ) that comprises an electric motor ( ) and a reduction actuator gear ( ) having two gear elements arranged coaxially in relation to each other ( and/or and/or ) that are interconnected with each other in terms of propulsion via a thread ( ) and that are displaced axially in relation to each other when they rotate relative to one another, whereby one of the gear elements ( ) is immobilized axially in a housing ( ) of the clutch servo unit, and the actuating motion of the other gear element ( ) is transferred to a throwout bearing ( ) of a clutch disk. It is proposed that the gear element ( ) that is axially displaceable relative to the housing ( ) is interconnected via a longitudinal guide ( ) with a rotor ( ) or a motor shaft ( ) of the electric motor ( ) in a fashion that is torsion-resistant but axially displaceable, and acts on the throwout bearing ( ) via an actuator ( ).
