Abstract: A drive with an electric motor, a housing and a direction-dependent brake, which includes a driver splined to a motor shaft, a drive output coupled freely pivotable around a small angle and shape-mated with the driver, several clamping devices and a clamping ring, in which the clamping devices cooperate with the clamping ring so that the brake conveys a torque from the electric motor to the driver output and brakes a back-driving torque of the drive output. The task of the invention is to present a brake in which no static redundancy occurs, which is simple to construct and in which no abrupt blocking is possible. This task is solved according to the invention in that the clamping ring is connected radially movable to the housing, a gearbox or a part attached to the housing so that the clamping ring after overcoming a defined force can be moved at least slightly radially by a clamping device.

Abstract: An electric drive for an electric motor. The electric drive is made up of components consisting of a brush holder plate and a bearing plate which are interconnected via at least one snap-on connector with an expandable catch means that is disposed on an external area of an electric motor, a drive motor, or a positioning drive in such a manner that it projects out. The electric drive can be securely mounted and handled in an economical manner without additional components and without complicated manufacturing equipment. This objective is accomplished by the fact that the expandable catch means is protected by a protective device against unintentional expansion of the catch means and thus loosening of the snap-on connector.

Abstract: A permanent magnet rotor having a shaft, a hollow cylindrical permanent magnet and an elastic connecting medium between the shaft and the permanent magnet. The permanent magnet is arranged co-axially around the shaft to ensure that the permanent magnet is mounted securely, that it is not damaged during large temperature fluctuations, and that it is not deflected impermissibly from the axis of rotation in case of heavy radial load. A simple installation process uses a mechanical connection between the shaft and the permanent magnet. This task is performed by virtue of the fact that an elastic connecting medium is arranged along the periphery of the shaft at several first areas in which the distance between the shaft and the permanent magnet is enlarged. These first areas are separated from the second areas in which the distance between the shaft and the permanent magnet is minimized but not zero.
