Description
Anordnung zur Befestigung äußerer ringförmiger, mit-ausgeprägten Polen versehener Ständerbleche bei elektrischen Kleinmaschinen. Es ist bei elektrischen Kleinmaschinen belcannt, zwecks Verringerung ihres Gesamtgewichtes an Stelle des Gehäuses zwei durch einen Lagerschild verbundene Arme anzuordnen, die durch einen Ring zusammengehalten sind, der zur weiteren Lagerung der Ankerwelle dient. Über diese Anne kann der mit ausgeprägten Polen versehene Ständerring von außen - aufgeschoben wenden, wobei die Arme in Nuten der Pole eingelagert sind. Diese Anordnung hat den Nachteil, daß die Arme nur aus einem un.magnetischen Material hergestellt werden können, um einen magnetischen Nebenschluß zu vermeiden, der das Kraftlinienfeld zwischen den Polen. erheblich schwächen würde. Diesen Nachteil vermeidet die Erfindung dadurch, " daß die Arme zwischen den Polen, also versetzt zu diesen angeordnet sind'.Arrangement for fastening outer ring-shaped, co-pronounced poles provided stator plates in small electrical machines. It's at electric Small machines are scanned to reduce their total weight instead of the Housing two arms connected by a bearing plate to be arranged by a Ring are held together, which is used for further storage of the armature shaft. Above The stand ring, which has pronounced poles, can be pushed on from the outside turn with the arms embedded in grooves in the poles. This arrangement has the Disadvantage that the arms are only made of a non-magnetic material can, in order to avoid a magnetic shunt, which the force line field between the poles. would weaken considerably. The invention avoids this disadvantage in that "the arms are arranged between the poles, that is, offset from them."
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel in den Abb. i und ä dargeste@lilt. Der aus Blechringen gebilidete Ständerkörper s, der zwei mit Magnetspulen in umwickelte Pole p, p besitzt, ist über die Anne b, b geschoben. Diese Anne können mit dem vorderen Lagerschi.ld gleich aus einem Stück bestehen oder aber auch durch ein besonders einzusetzendes Lagerschild miteinander verbunden sein, während sie an ihrem hinteren Ende durch einen kreisförmigen Flansch zusammengehalten sind, in den nach Einbringen der Ankerwelle mit dem Läufer e ein Lagerschild d eingesetzt und mittels Schrauben e, e festgeschraubt wird. Der Ständerkörper s kann vor oder nach dem Einsetzen des Läufers c auf die Arme b aufgeschoben werden. Die in den Ständerbl.echen vorgesehenen Nuten, die über die Arme b greifen, liegen zwischen den Polen p, also um go° zu ihnen verdreht.In the drawing, the subject of the invention is shown in one embodiment in Figs. I and ä dargeste @ lilt. The stator body s formed from sheet metal rings, which has two poles p, p wound with magnetic coils, is pushed over the arms b, b. These arms can consist of one piece with the front bearing shield, or they can also be connected to one another by a bearing shield that is specially designed to be used, while they are held together at their rear end by a circular flange into which, after the armature shaft with the rotor e has been introduced End shield d is inserted and tightened using screws e, e. The stator body s can be pushed onto the arms b before or after the rotor c has been inserted. The grooves provided in the stator blades, which reach over the arms b, lie between the poles p, i.e. rotated by go ° to them.
