Abstract: A drive device includes an electric drive motor, a housing with a housing cover, at least one shaft that is powered by the drive motor and compensating element(s) for compensating the axial play of the shaft. The compensating elements include at least one axially elastic, deformable elastomer element having at least one contact surface. The contact surface(s) has a PTFE, PET or corresponding coating.

Abstract: A cover plate for an electric motor which has a brush array and interference suppression devices has additional electronic components mounted directly on the cover to determine the speed of the electric motor and for diagnosis. Contact with the interference suppression devices and the additional electronic components is achieved through electrical conductors which are located directly on the cover plate. Flexible use of the electric motor is ensured through the high temperature stability of the cover plate.

Abstract: A drive device includes an electric drive motor, a housing, at least one shaft which is driven by the drive motor, and a compensating member for compensating the axial clearance of the shaft. A spring ring disk, which can be expanded radially counter to an elastic force and has two stopping surfaces radially extending towards each other on the axis of the shaft in the form of a wedge, is arranged on the shaft as the compensating member. The shaft has a ring-shaped projection which matches one of stopping surfaces and the housing has an annular collar which matches the other stopping surface. The spring ring disc is pre-tensed and arranged in between the projection and the annular collar.

Abstract: A process for producing an electronic component, such as a Hall sensor, in which electronic parts are located in a plastic housing. The process includes the steps of locating the electronic parts in a hot-melt adhesive, allowing the hot-melt adhesive to solidify, and finish-extrusion coating the electronic parts in the solidified hot-melt adhesive to form the housing. In an alternative embodiment, the process may also include the step of embedding the electronic parts in the hot-melt adhesive. In yet another embodiment, the process may also include the step of extrusion-coating the electronic parts with the hot-melt adhesive. Materials having substantially similar coefficients of thermal expansion may be used for the hot-melt adhesive used for mounting the electronic parts, and for the finish-extrusion coating that forms the housing to minimize effects of thermal expansion. The process is efficient and cost effective.

Abstract: The invention relates to a drive device (1) comprising an electric drive motor (2), a housing (4), at least one shaft (8) which is driven by the drive motor and means for compensating the axial clearance of said shaft. The invention is characterized in that a spring ring disk (19), which can be expanded radially counter to an elastic force and has two stopping surfaces radially extending towards each other on the axis of the shaft in the form of a wedge, is arranged on the shaft as said compensating means. The invention is also characterized in that shaft has a ring-shaped projection (22) which matches one of stopping surfaces and the housing has an annular collar (23) which matches the other stopping surface. The spring ring disc (19) is pre-tense and arranged in between the projection (22) and the annular collar (23).

Abstract: An incandescent plug for an air-compressing internal combustion engine, with a plug body (3), with a connector (5) for the application of electrical current and with an incandescent tube (2) which is attached to the plug body at one end is closed at its opposite end, and a wire filament-like resistance element (4) which embedded in an electrically insulating material (7) in the incandescent tube (2), is able to be heated with lower electrical output by the wire filament-shaped resistance element (4) being confined within the region of the opposite end of the incandescent tube which is remote from the plug body (3).
