Description

Die Erfindung bezieht sich auf einen Elektromotor, der mit einer Einrichtung zur Abführung der sich beim Arbeitslauf entwickelnden Wärme ausgerüstet ist. Es handelt sich in erster Linie um Kleinmotoren, deren Läuferdurchmesser praktisch nicht die Möglichkeit bieten, den Läufer mit Durchzugslüftkanälen auszuführen.The invention relates to an electric motor with a device is equipped to dissipate the heat that develops during the work cycle. It are primarily small motors, the rotor diameter of which is practical do not offer the possibility of designing the runner with ventilation ducts.

Erfiridu-ngsgemäß sollen in metallischem Anschluß an die Stirnflächen des Läufers in Kreisreihe spitzwinklige Rohrkrümmer in der Form angeordnet werden, daß in diesen beim Lauf des Motors Saugwirkungen entstehen, die Frischluft in das Motorinnere hineinbringen, wobei der eine Rohrschenkel mit Lüftungsfahnen versehen ist, die zusätzlich Saugwirkungen hervorrufen.According to the invention, they should have a metallic connection to the end faces of the runner in a circular row acute-angled pipe bends are arranged in the form, that suction effects occur in these when the engine is running, the fresh air into the Bring the inside of the motor in, with one pipe leg provided with ventilation lugs which also cause suction effects.

Eine Ausführungsmöglichkeit der Erfindung ist in der Zeichnung schematisch dargestellt.One possible embodiment of the invention is shown schematically in the drawing shown.

Die mit dem Läufer i verbundenen Rohrkrümmer sind mit 2 bezeichnet, sie sind in einem Zwischenstück 3 (Kurzschlußringe) eingebettet bzw. hieran befestigt. ,Dieses Zwischengtück 3 seinerseits ist an der Stirnfläche des Läufers i befestigt. An schräg nach oben gerichteten Rohrschenkeln 4 sind Lüftungsfahnen angebracht, die beim Lauf des Motors in der durch Pfeillinien angedeuteten Richtung einen stetigen Frischluftzug erzeugen. Gleichzeitig entstehen an den äußeren Ausmündungen der Rohrkrümmer zwei Saugwirkungen, die ebenfalls (vgl. die Pfeillinien) Frischluft an die Stirnwand des Läufers und in das Motorinnere bringen, so daß intensive Luftbewegungen im Motorinnern entstehen, die eine wirksame Wärmeabfuhr im Gefolge haben.The pipe bends connected to the rotor i are denoted by 2, they are embedded in an intermediate piece 3 (short-circuit rings) or attached to it. This intermediate piece 3 in turn is attached to the end face of the rotor i. Ventilation flags are attached to pipe legs 4 pointing upwards at an angle, which become steady when the engine is running in the direction indicated by the arrow lines Generate fresh air. At the same time, the pipe bends are created at the outer openings two suction effects, which also (see the arrow lines) fresh air to the front wall of the rotor and into the interior of the motor, so that intensive air movements inside the motor arise, which have an effective heat dissipation in the wake.
