  Elektrisch angetriebener Scheibenwischer, insbesondere für Fahrzeuge. 



   Der Gegenstand vorliegender Neuerung bezieht sich auf durch einen kleinen elektrischen Motor angetriebene Scheibenwischer, bei denen zumeist der Motor an der einen und der Wischer an der andern Seite der durchsichtigen Scheibe angeordnet ist. Um durch den Aufbau die Sicht nicht zu beeinträchtigen ist es erwünscht, dem Motor eine schmale, langgestreckte Form zu geben. Vorteilhaft ist ferner eine Querschnittsform des Motors, bei welcher sein Schwerpunkt nahe der Scheibe liegt. 
 EMI1.1 
 systems für die Felderregung parallel zur Ankerachse gerichtet und unbewickelt sind. 



   In   den Fig. 1 und 2sind zweiAusführungsbeispiele der Erfindung teilweise im Schnitt veranschaulicht.   



   In einem zylindrischen Gehäuse mit   kreisförmigem Querschnitt   liegen parallel zur Achse 1 des Ankers 2 zwei gerade Profilstäbe 3 und   4   aus Magnetstahl, deren Enden durch Jochstücke   J   und 6 gehalten werden, von denen das eine   (6)   aus magnetisch leitendem Werkstoff besteht. An dem einen Ende der Achse 1 ist ein Getriebe 7,   8,   durch das die Drehung des Ankers 2 auf die Welle 9 des Wischerarmes 10 übertragen wird. Mittels zweier Bolzen 11 wird der Scheibenwischer an der (nicht gezeichneten) durchsichtigen Scheibe befestigt. 



   In Fig. 2 ist den Stäben 3 und 4 eine Erregerwicklung 12 zugeordnet, die an dem Jochstück 6 angebracht ist. 



   Das Erregersystem kann an Stelle der gezeichneten zwei Pole auch ein Vielfaches davon haben.

  Electrically powered windshield wipers, in particular for vehicles.



   The subject of the present innovation relates to windshield wipers driven by a small electric motor, in which mostly the motor is arranged on one side and the wiper on the other side of the transparent window. In order not to impair the view through the structure, it is desirable to give the engine a narrow, elongated shape. A cross-sectional shape of the motor in which its center of gravity is close to the disk is also advantageous.
 EMI1.1
 systems for field excitation are directed parallel to the armature axis and are not wound.



   In Figures 1 and 2, two embodiments of the invention are illustrated partly in section.



   In a cylindrical housing with a circular cross-section are parallel to the axis 1 of the armature 2 two straight profile bars 3 and 4 made of magnetic steel, the ends of which are held by yoke pieces J and 6, one of which (6) consists of magnetically conductive material. At one end of the axle 1 there is a gear 7, 8 through which the rotation of the armature 2 is transmitted to the shaft 9 of the wiper arm 10. The windshield wiper is attached to the transparent window (not shown) by means of two bolts 11.



   In FIG. 2 the rods 3 and 4 are assigned an excitation winding 12 which is attached to the yoke piece 6.



   Instead of the two poles shown, the excitation system can also have a multiple thereof.



   PATENT CLAIMS:
1. Electrically driven windshield wiper, in particular for vehicles, characterized in that the legs (3, 4) of the magnet system for the field excitation of the electric motor are directed parallel to the armature axis (1) and are not wound.
