Description
Bei bekannten Stromwendern für elektrische Maschinen mit zwischen den einzelnen Stegen angeordneten Glimmerschichten ragen diese Glimmerschichten über die gegen den Wikkelkopf des Ankers gerichtete Stirnfläche des Stromwenders hinaus. Es wird dabei in der Hauptsache der Zweck verfolgt, zu vermeiden, daß beim späteren Einlöten der Wicklungsenden abfließendes Lot eine Verbindung zwischen zwei benachbarten Stegen und damit einen praktisch nicht mehr zu beseitigenden Kurzschluß herstellen kann.In known commutators for electrical machines with between the individual webs arranged mica layers, these mica layers protrude over the against the winding head the armature facing face of the commutator addition. The main purpose is to avoid that when the winding ends are later soldered in, solder that flows off creates a connection between two adjacent webs and thus can produce a short circuit that can practically no longer be eliminated.
Die einzulötenden Wicklungsenden finden jedoch an den Stellen über den sektorförmigen Hohlräumen, die zwischen den überstehenden Glimmerblättchen verbleiben, keine tragfähige Unterlage. Diese Tatsache hat insbesondere bei 'elektrischen Maschinen, die starken Erschütterungen ausgesetzt sind, z. B.However, the winding ends to be soldered are located at the points above the sector-shaped ones Cavities that remain between the protruding mica flakes are not viable Document. This fact has especially in 'electrical machines that are exposed to strong vibrations, e.g. B.
Antriebsmotoren für handgeführte Elektrohammer, zu Brüchen der Wicklungsenden am Stromwender Anlaß gegeben.Drive motors for hand-held electric hammers, to break the winding ends on Commuter given occasion.
Gemäß der Erfindung sind zur Schaffung einer festen Unterlage für die Wicklungsenden die überstehenden Glimmerblättchen gegen den Stromwender umgeknickt, und der dadurch entstehende freie Raum zwischen Stromwender und Wickelkopf ist mit Isolierstoff fest ausgefüllt. Durch diese Anordnung werden also die Nachteile der überstehenden Glimmert eile beseitigt, ohne daß deren Vorteile bei der Lötung preisgegeben werden.According to the invention are to create a solid base for the winding ends the protruding mica leaves bent over against the commutator, and the resulting free space between The commutator and winding head are firmly filled with insulating material. Through this arrangement the disadvantages of the protruding mica are therefore eliminated without sacrificing their advantages are disclosed during soldering.
Besonders geeignet zur Ausfüllung ist Schnur, die fest in den freien Raum gewikkelt und gegebenenfalls mit Lack getränkt wird. Wenig gezwirnte langfaserige Hanfschnur hat dabei den Vorzug besonderer Eignung zur Lackaufnahme und innigen Verbindung mit den Nachbarlagen.Cord that is tightly wound in the free space is particularly suitable for filling and, if necessary, impregnated with varnish. Little twisted long fiber hemp cord has the advantage of being particularly suitable for absorbing paint and intimately connecting with the neighboring layers.

Die auf den Grundkörper λ aufgekeilten Stromwenderstege b sind durch. Glimmer-Zwischenschichten c, die bei den bekannten Ausführungen mit ihren Enden c' aus der Stirnwand des Stromwenders herausragen (Abb. 1), gegeneinander isoliert. Bei dem Stromwender gemäß der Erfindung sind diese überstehenden Enden c' umgeknickt und bilden auf der Stirnfläche eine Glimmerlage c". Der zwischen dieser GHmmerlage c", dem Grundkörper α und dem Wickelkopf d liegende freie Raum ist mit Hanfschnüren e vollgewickelt, die den in die Fahnen b' der Stege & eingelöteten Wicklungsenden / in unmittelbarer Nähe der Stirnfläche des Stromwenders als feste Unterlage dienen.The commutator webs b wedged onto the base body λ are through. Mica intermediate layers c, which in the known designs protrude with their ends c 'from the end wall of the commutator (Fig. 1), insulated from one another. In the commutator according to the invention, these protruding ends c 'are bent over and form a mica layer c "on the end face. The free space between this GHmmerlage c", the base body α and the winding head d is fully wrapped with hemp cords e , which enclose the Flags b 'of the webs & soldered winding ends / in the immediate vicinity of the end face of the commutator serve as a solid base.
