Abstract

Die Erfindung betrifft eine drehmomentabhängige Abschaltvorrichtung für einen Elektromotor, der einen Anker (7) und einen an einem Gehäuse (1) angebrachten Stator (8) aufweist, mit einer stabförmigen Lagereinrichtung für den Stator (8), deren eines Ende mit dem Stator (8) verbunden ist und deren anderes Ende in einem feststehenden Motorlager gelagert ist, und mit mindestens einem Schalter (15, 25), der bei Erreichen eines vorbestimmten Drehmomentes aufgrund der Drehbewegung des Stators (8) relativ zu einem Abschnitt der stabförmigen Lagereinrichtung mittels eines innerhalb des Gehäuses (1) angeordneten Schaltelementes (17, 27) betätigbar ist. Bei solchen Abschaltvorrichtungen besteht die Aufgabe, sie platzsparend und mit im Falle eines Blockierens des Elektromotors, insbesondere seiner Welle, für den Motor günstigen Eigenschaften auszuführen. Die Aufgabe wird dadurch gelöst, daß die Lagereinrichtung als Torsionsfederelement, insbesondere -stab (12), ausgebildet ist und daß der Schalter (15, 25) innen am Gehäuse (1) und das Schaltelement (17, 27) an einem im Gehäuse (1) liegenden im wesentlichen ortsfesten Zwischenabschnitt (31) des Torsionsfederelementes oder umgekehrt zur Betätigung des Schalters (15, 25) mit dem Schaltelement (17, 27) angebracht sind.

The invention relates to a torque-dependent shutdown device for an electric motor, which has an armature (7) and a stator (8) attached to a housing (1), with a rod-shaped bearing device for the stator (8), one end of which is connected to the stator (8 ) is connected and the other end of which is mounted in a fixed motor bearing, and with at least one switch (15, 25) which, when a predetermined torque is reached due to the rotational movement of the stator (8), relative to a section of the rod-shaped bearing device by means of an inside the Housing (1) arranged switching element (17, 27) can be actuated. The task of such shutdown devices is to save space and to perform them with favorable properties for the motor if the electric motor, in particular its shaft, is blocked. The object is achieved in that the bearing device is designed as a torsion spring element, in particular rod (12), and in that the switch (15, 25) on the inside of the housing (1) and the switching element (17, 27) on one in the housing (1 ) lying essentially stationary intermediate section (31) of the torsion spring element or vice versa for actuating the switch (15, 25) with the switching element (17, 27).
