Erfindung betrifft einen Elektromotorschildes 2 untergebracht sind. Zur Führung und Lagerung der achsparallel zur Motorwelle 4 verstellbaren
Magnetscheibe 18 dienen die Führungsbolzen 17, die in die Bohrungen   1T der   Magnetscheibe 18 glei- tend ausragen. 



   Die Magnetscheibe 18 ist an ihrer der Bremsscheibe 10 zugewendeten Seite mit einem Bremsbelag 19 versehen. 



   Zur verdrehungssicherenverriegelung der auf das Feingewinde   4'der Welle 4 aufschraubbaren Brems-   scheibe 10 mit dem Stirnende dieser Welle 4 dient die Riegelplatte   21 :   diese trägt einen leistenförmigen
Fortsatz 22, der in einer Nut der Bremsscheibe 10 und eine mit dieser fluchtende Nut der Welle 4 einzu- greifen vermag, wenn diese Nuten durch Verdrehen zum Übereinstimmen gebracht worden sind. Eine Befestigungsschraube 24 dient zur Verankerung der Riegelplatte 21 am Stirnende der Welle 4. 



   Die Wirkungsweise der erfindungsgemässen Vorrichtung ist wie folgt :
Beim Einschalten des zur Motorversorgung dienenden Stromes wird die Ständerwicklung 5 und die Magnetwicklung 13 stromführend und die Magnetscheibe 18 wird gegen den Einfluss der Federn 16 gegen den Schild 2   gedrückt :   die Bremsscheibe 10 des Lüfters 11 wird freigegeben und die Motorwelle 4 kann in Rotation versetzt werden. 



   Beim Ausschalten des Motors und Stromloswerden des Magneten 13 pressen die Druckfedern 16 die Magnetscheibe 18 gegen die Bremsscheibe   10 ;   die Bremsbeläge 19 sorgen für eine unverzügliche Stillsetzung der Motorwelle 4.

Invention relates to an electric motor shield 2 are housed. For guiding and mounting the axially parallel to the motor shaft 4 adjustable
The magnet disk 18 is used by the guide pins 17, which protrude into the bores 1T of the magnet disk 18 in a sliding manner.



   The magnetic disk 18 is provided with a brake lining 19 on its side facing the brake disk 10.



   The locking plate 21 serves to lock the brake disk 10, which can be screwed onto the fine thread 4 'of the shaft 4, to the end of this shaft 4 in a manner that prevents it from twisting: it carries a strip-shaped one
Extension 22, which is able to engage in a groove in the brake disk 10 and in a groove in the shaft 4 that is aligned with the latter, when these grooves have been brought into alignment by turning. A fastening screw 24 serves to anchor the locking plate 21 at the front end of the shaft 4.



   The operation of the device according to the invention is as follows:
When the current used to supply the motor is switched on, the stator winding 5 and the magnet winding 13 become live and the magnet disk 18 is pressed against the influence of the springs 16 against the shield 2: the brake disk 10 of the fan 11 is released and the motor shaft 4 can be set in rotation .



   When the motor is switched off and the magnet 13 is de-energized, the compression springs 16 press the magnet disk 18 against the brake disk 10; the brake linings 19 ensure that the motor shaft 4 is stopped immediately.

PATENTANSPRUCH : Elektromotor mit elektromagnetisch betätigbarer mechanischer Bremsvorrichtung, wobei zur Aus- übung des Bremsmomentes auf eine mit der Motorwelle lösbar verbundene Bremsscheibe od. dgl. eine zwischen dieser rotierenden Bremsscheibe und einem feststehenden Lagerschild koaxial verstellbare Magnetscheibe od. dgl. vorgesehen ist, die gegen den Druck mindestens einer Feder unter dem Einfluss eines Elektromagneten ausser Wirkung gehalten wird, solange dieser Elektromagnet mit Strom beschickt ist, dadurch gekennzeichnet, dass der ferromagnetische Kern (12) des zur Verstellung der Magnetscheibe (18) dienenden Elektromagneten (12, 13) von dem aus Leichtmetall, z. B. aus Siluminguss, bestehenden Lagerschild des Motorgehäuses umgossen ist. PATENT CLAIM: Electric motor with an electromagnetically actuated mechanical braking device, whereby a magnetic disk or the like that is coaxially adjustable between this rotating brake disk and a stationary end shield is provided to exert the braking torque on a brake disk or the like detachably connected to the motor shaft, which against the pressure at least a spring under the influence of an electromagnet is kept inoperative as long as this electromagnet is charged with current, characterized in that the ferromagnetic core (12) of the electromagnet (12, 13) used to adjust the magnetic disc (18) is different from the one made of light metal, z. B. is cast from Siluming, existing end shield of the motor housing is cast.
