Abstract: The present invention relates to a brush cover for a brush-commutated electric motor. The brush cover comprises at least one lever brush which is mounted rotatably about an axis at the brush cover by means of a bolt. According to the invention, the bolt is surrounded, at least in sections, by at least one damping sleeve of an elastomer.

Abstract: The invention relates to an electric motor for high-temperature applications. The electric motor comprises a rotor and a stator with a hollow-cylindrical, ironless stator winding of stoved-enamel wire. Furthermore, a soft-magnetic return is provided which encloses the stator winding.

Abstract: A power transmission unit is disclosed which includes a first input shaft and a second input shaft which can be mutually driven by a motor shaft in opposite directions. A driven shaft can be coupled, depending on the desired sense of rotation of the driven shaft, to the first or to the second input shaft, and can engage with a first output shaft and with a second output shaft. The first output shaft can be directly coupled with the first input shaft via a first magneto-rheological clutch, and the second output shaft can be directly coupled with the second input shaft via a second magneto-rheological clutch. A magneto-rheological clutch is disclosed with a coil powered by wireless energy transmission between a sender connected to a stationary housing and a receiver rotating with the coil.

Abstract: The present invention relates to a method of connecting a hub component, in particular a pinion, to a shaft. The hub component and the shaft consist of different materials, that is of ceramics and metal. A connecting element of metal is connected both to the hub component and to the shaft. According to the invention, it is provided that the hub component and the shaft are connected to the connecting element by a material bond. The invention furthermore provides a connection between a shaft and a hub component.
