Abstract: An electric motor having a cup-shaped motor housing for containing a shaft and a motor cover that closes the motor housing. The motor cover has a peripheral section extending essentially radial to the shaft and an inner section extending essentially axial to the shaft. The inner section at least partially, radially encloses a bearing for supporting the shaft. The electric motor is fastened to a connecting block in order to be connected to a subassembly to be rotated by the shaft. The peripheral section of the motor cover and the connecting block touch each other on at least one support. The motor housing and the connecting block are axially clamped in relation to each other by means of a clamping element. The peripheral section of the motor cover is axially connected to the motor housing in detent fashion.

The pump housing can be mounted on the face end (R) of the motor housing opposite the cup bottom, and that a cap is provided, which can be pressed into the motor housing on the open face end and seals off this housing, the cap has a central bore for a drive shaft and at least one further opening, near the edge, for a through-plated hole.

Abstract: The invention relates to an electric motor having a preferably cup-shaped motor housing and a contacting device for supplying electrical energy from outside to corresponding motor parts. The contacting device includes a busbar, which is disposed in the interior of the housing and can be shifted at least partially through an opening in a housing wall, and the outer end of the busbar is electrically connectable to a connection line and the inner end of the busbar is electrically connectable to corresponding motor parts.

Abstract: A method and device for positioning non-linear machine parts using a timing element, particularly for machine parts that are in non-linear motion. The invention has a pair of sensors spaced apart for reading bar code marks on the timing unit when the timing unit is disposed on a circular or spherically-shaped carrier surface. Where long surfaces are involved, the ends of the timing unit or clock ruler are butt-jointed together and include a gap having a width deviating from the window openings of the bar code. Thus, the second sensor, which is connected to a second comparator, contains a test circuit for the code signals that are received. When the code signals do not correspond to the width of the bar code pitch, they are passed over to a second counter, and the first counter is disconnected from the line.

Abstract: A motion sensor has a carrier which rotatably supports a shaft. One or more eccentric weights are mounted on the shaft for rotation therewith. The carrier is supported by pins which are normal to the shaft and rotatable on bearings. One of the pins carries a disk with marks in the form of lines, and a sensing device for the marks is disposed adjacent the disk. This pin further carries a transmission component which cooperates with a transmission component on the shaft. When an object on which the motion sensor is mounted is tilted about the axis of the shaft, the weights are displaced from an equilibrium position. The weights return to the equilibrium position under the action of gravity thereby rotating the shaft which, in turn, rotates the disk via the transmission components. If the object is tilted about the axes of the pins, inertia causes rotation of the disk. The rotation of the disk is detected by the sensing device which can trigger an alarm.

Abstract: A method and device for positioning moving machine parts by using two sensors to detect the spacing of code markers on a code bearing part attached to the machine part and counting the number of code markers detected while accounting for uneven spacing between code markers which invariably occur when two code bearing parts are joined for use on a single machine part.

Abstract: A drive for a printer includes a printing roller which is driven by a step motor located at one axial end of the roller. A monitoring unit for the printing roller is disposed at the other axial end of the roller and comprises a belt which is mounted on two guide rollers. The rotational axes of the guide rollers are parallel to the rotational axis of the printing roller. The outer surface of the belt frictionally engages a portion of the peripheral surface of the printing roller so that the belt moves in response to rotation of the printing roller. One of the guide rollers for the belt drives a synchronizing disc having indicating elements which are sensed by a detector. The detector generates a synchronizing signal whenever an indicating element is detected, and the synchronizing signals are sent to a control unit. The control unit compares the synchronizing signals with reference signals and sends control signals to the motor when the synchronizing signals deviate from the reference signals.

Abstract: A unit comprising a drive motor and a radial piston pump is proposed, in which unit an armature of the drive motor and an eccentric of the radial piston pup are carried by a common unitary shaft which has three bearings. A three-bearing mounting, known from the prior art, for a shaft of this kind consists of three ball bearings, which are expensive. The invention proposes to replace the ball bearing situated at the greatest distance from the eccentric in the prior art by a slide bearing, and to design the latter as a sintered metal bearing and to impregnate it with a viscous lubricant. The unit according to the invention can be used as a component of an anti-lock device of a vehicle brake installation or of a drive-slip control device acting on driven wheels.
