Electric motor, in particular electric small-size motor for driving

A windshield wiper system for motor vehicles includes an electric motor which drives at least one wiper during normal wiper operation, too and fro between two reversing positions within a wiping area. When the wiper system has been switched off by means of an operating switch, the wiper is moved to a concealed parking position outside the wiping area. Upon switching on of the wiper system and during normal operation the motor runs in one direction of rotation, but for moving the wipers into the parking position the motor runs in the other direction of rotation. A position switch is changed over by a switching member coupled with a rotating drive member of the electric motor. The position switch, after the operating switch has been switched off, releases a signal for reversing the polarity and in the parking position releases a signal for switching off the electric motor. So that the wiping cycle for entering the parking position begins in the first reversing position adjacent to the parking position and the wiper occupies the first reversing position in the dwell time interval of intermittent operation, the position switch is changed over independently of the direction of rotation of the electric motor and always in the same position of the drive member.

Windshield wiper system

This invention describes an electric motor on whose gear housing cap are secured plug contacts for a mating plug. Pin terminals which project perpendicularly from the gear housing cap are used as plug contacts. Various pin terminals are fixed on the cap, while other pin terminals are carried by a separate structural member which may be locked on the cap.

Windshield wiper motor

A windshield wiper motor drive unit is described wherein a gear cover, connector receptacle and brush plate are integrally formed as a one piece plastic part.

Electric drive unit especially for windshield wipers of a motor vehicle

A windshield wiper motor is disclosed in which there is a gear mechanism in a one piece plastic housing. The gear housing also houses the electrical terminals for the motor brushes and the brush springs. All these elements are placed in the one piece plastic housing.

Terminal connections and housing for a small electric motor for

An electric motor drive unit for windshield wipers includes an electric motor having an electrical connection plug housing and a brush holder plate. The plug housing and brush holder plate are provided as an integral unit. The unit is secured between the motor housing and the gear housing. This arrangement and assembly of the drive unit is simplified and less expensive to manufacture.

Windshield wiper electric drive unit

An electric drive unit particularly adapted for actuating windshield wiper assemblies includes a motor having it's armature shaft carrying aportion having two oppositely pitched worm threads. Two worm gear wheels are disposed each on opposite sides of the threaded portion and in engagement therewith. The axes of rotation of the worm wheels are in parallel. Two spur wheels are each concentrically seated on a respective worm wheel. The spur wheels each engage a wheel having its axis of rotation located in a plane defined by the axes of rotation of the worm wheels. The toothed wheel is connected to a drive shaft.
