Abstract: A pole wheel of the type driven in rotation by a shaft employs a sensor system disposed on the pole wheel for detecting rotations of the shaft. The pole wheel includes a first component in the form of a hollow magnet body and a second component that is disposed as a retaining part for the first component and is seated firmly on the shaft and is embodied integrally, for the sake of streamlined connection to the first component, with connecting means. Recesses, which for instance can be embodied in groovelike fashion, may be disposed on the second component, that is, the retaining part seated solidly on the shaft, and the first component is injected molded onto the second component, creating positive engagement connecting means comprising the material of the magnet body.

Abstract: An electric motor drive mechanism, in particular a power-window drive for a motor vehicle, with an electric motor (10) and a set of motor electronics (14) connected with it that are encompassed by an electronics housing (20), as well as a securing device (16), which supports the electronics housing (20) in relation to a pole pot (22) of electric motor (10). The proposal is that the securing device (16) have a guide (26) for connection to an opposing guide (38) disposed on the electronics housing (20) and have the ability to engage in detent fashion with the drive mechanism.

Abstract: An electric motor drive mechanism, in particular a window control drive mechanism for a motor vehicle, has an electric motor (10), which has a motor armature shaft (12) that is operatively connected to a gear unit (14) surrounded by a gear housing (16), and also has a motor electronics unit (18) surrounded by an electronic housing (20). The electronics housing (20) has a guide rail (22), extending radially to the motor armature shaft (12), for insertion of the electronics housing (20) via a counterpart guide (23) disposed on the gear housing (16).

Abstract: In a sensor device including a magnetic field sensor which is arranged in stationary fashion and configured as a Hall sensor and is magnetically coupled to at least one stationary magnetic flux conductor which senses a variable magnetic field and delivers it to the Hall sensor, the Hall sensor delivering to an electronic control circuit an electrical signal which depends on the change in the magnetic field, in order to achieve a reduction in the space required for the electronic control circuit and the Hall sensors it is proposed the at least one Hall sensor, combined with at least one element of the electronic control circuit into an application-specific integrated circuit (ASIC), be arranged in an electronic component.

Abstract: A drive device for a part of a vehicle that can be adjusted between terminal positions, in particular the roof panel of a vehicle roof, having an electric motor that is connected to a pinion via a first step-down gear. A switch device that controls the electric motor for stopping the electric motor in at least one predetermined position of the adjustable part, and a second step-down gear that moves a switch body. A magnetic-field-sensitive sensor, controllable by the switch body, for controlling the switch device. A conductor track board inside a housing and extending with an extension over the path of motion of the switch element. The magnetic-field-sensitive sensor is disposed at a radial distance from the circular path of motion of the switch body and bridges the distance between the magnetic-field-sensitive sensor and the path of motion of the switch body by means of magnetic flux guide bodies.

Abstract: A method is described of operating a sliding roof system for a motor vehicle. The sliding roof system includes a sliding roof, a sliding roof drive with a sliding roof motor, a device for controlling the sliding roof drive, and a device for emergency displacement of the sliding roof. Operation of the device for emergency adjustment of the sliding roof is detected, and this information is relayed to the device for controlling the sliding roof drive. Such a sliding roof system is also described.

Abstract: A brush holder equipped as a component on a printed circuit board and is inserted into a recess provided in a transmission housing of the drive device and thereby can be slid in the radial direction over a commutator of an already completely assembled armature. The drive device according to the invention is provided for moving a sliding sunroof of a vehicle.

Abstract: An electric motor operated actuating device for a blocking button of a door lock for central locking and unlocking of doors of a motor vehicle comprises an electric motor actuatable by a door key and provided with a driven shaft, a turning lever connectable with the blocking button for transferring the blocking button to a blocking position which locks the door lock and to an unblocking position which releases the door lock, a transmission including a turning member with a coulisse and a driver rotatable about a rotary axis and provided with a driver cam which runs in the coulisse. The coulisse is formed so that the turning member in each end rotary position of the driver cam is turnable by manual actuation of the blocking button through the turning lever by the driver cam to one of the two end turning positions, and during rotation of the driver cam from the one end rotary position to another end rotary position is turned to one or another end turning position.

Abstract: A drive device for movable structural component units, e.g. for a window lifter in motor vehicles, has a reversible electric motor and a control device for switching on the motor with predetermined rotating direction from its rotor shaft at a switch-on command. In order to manage with the lowest possible drive output and to keep the characteristic lines to be maintained by the motor within the narrowest possible range, both the motor and the structural component unit itself are constructed so as to be without friction and active self-locking is provided to keep the structural component unit in its movement end positions. For this purpose a sensor detects rotational movements of the rotor shaft from the movement end position and the control device is connected with an evaluating unit which evaluates the sensor signals and generates a switch-on command in a rotating direction opposite the rotational movement of the rotor shaft.
