Ein Lagerschild 4 ist mittels Schrauben 5 an dem Gehäuse 1 befestigt. In den Lagerschild 4 sind Bolzen 6 eingeschraubt, die aus einer Stirnfläche 7 des Lagerschildes 4 parallel zur Motorwelle 8 herausragen. Mittels einesThe electric motor shown has a housing 1 in which a laminated stator core provided with a stator winding 2 3 is provided. A bearing plate 4 is fastened to the housing 1 by means of screws 5. In the end shield 4 are bolts 6, which protrude from an end face 7 of the end shield 4 parallel to the motor shaft 8.

In der dargestellten Bremsstellung liegt der linke Bremsbelag 12 an der Stirnfläche 7 des Lagerschildes 4 und der rechte Bremsbelag11 non-rotatable on the motor shaft 8, but mounted displaceably in the axial direction. On the outer edge of the brake disc 11, brake pads 12 are attached on both sides. In the braking position shown, the left brake pad 12 is on the end face 7 of the end shield 4 and the right brake pad

Die Ankerscheibe 14 wird durch vorgespannte Druckfedern 15, die in Aussparungen 16 eines Magnetkörpers 17 angeordnet sind, gegen den rechten Bremsbelag 12 gedrückt. Der Magnetkörper 17 ist mit einer Magnetwicklung 18 versehen, die beim Einschalten des Elektromotors unter Strom gesetzt wird. Die Druckfedern 15 bestimmen das Brems Moment. Die Einstellung des Druckes der Druckfedern 15 und damit des Bremsmomentes erfolgt; mittels Gewindebolzen 19, die in entsprecherde Gewindebohrungen des Magnetkörpers 17 eingeschraubt sind und an denen sich die Druckfedern 15 abstützen. In der dargestellten Bremsstellung bilden Stirnflächen 20 und 21 der Anker scheibe 14 und des Magnetkörpers 17 einen Luftspalt12 on an end face 13 of an armature disk 14. the Armature disk 14 is secured by pretensioned compression springs 15 which are arranged in recesses 16 of a magnet body 17, pressed against the right brake pad 12. The magnet body 17 is provided with a magnet winding 18, which when switched on the electric motor is energized. The compression springs 15 determine the braking torque. The setting the pressure of the compression springs 15 and thus the braking torque takes place; by means of threaded bolts 19, which are in corresponding threaded holes of the magnet body 17 are screwed in and on which the compression springs 15 are supported. In the illustrated Braking position form end faces 20 and 21 of the armature disk 14 and the magnet body 17 an air gap

The balls 25 are nättels disc springs 27 against the conical wall or the bolt 6 pressed. As a result, locking mechanisms are formed that displace the armature disk 14 and the magnet body 1? allow to the left according to the figure, but prevent a shift to the right.
An ihrem rechten Ende gemäß der Figur ist die Motorwelle 8 mit einem Lüfter 28 versehen, der zugleich mit der Einscheibenbremse durch eine Abdeckhaube 29 abgedeckt ist, die am Lagerschild 4 befestigt ist und im Bereich des Lüfters 28 Öffnungen 30 aufweist.At its right end as shown in the figure, the motor shaft 8 is provided with a fan 28, which at the same time with the single-disc brake is covered by a cover hood 29 which is fastened to the bearing plate 4 and in the area of the fan 28 Has openings 30.
