Description
Einbaumotor mit einem das Ständerblechpaket, die Lagerung der Motorwelle und die Bürstenhalter tragenden Rahmen Einbaumotoren werden vielfach in der Weise ausgebildet, daß das Ständerblechpaket von einem Rahmen aus unmagnetisierbarein Metall getragen wird, der die Lagerung für die Motorwelle sowie die Bürstenhalter trägt. Um einen guten mechanischen Aufbau zu erzielen, liegt der Rahmen zweckmäßig innerhalb des Blechpaketes, so daß .er eine kurzgeschlossene Windung in dem von der Ständerwicklung erzeugten Feld darstellt. Bei einem Ständerblechpaket von geringer axialer Abmessung werden durch diese K-urzschlußwindung verhältnismiil.)ig geringe Nachteile verursacht. Hat das Ständerblechpaket jedoch eine größere axiale Länge, so sind die durch den Rahmen hervorgerufenen Stromwärmeverluste bereits von größerer Bedeutung. Um diese Verluste zu verringern, ist bereits vorgeschlagen worden, den Rahmen nicht völlig geschlossen auszubilden, sondern an einer Stelle einen Schnitt durch seinen Querschnitt zu legen, der durch Zwischenlagen aus Isolierstoff überbrückt wird, so daß der Rahmen keine geschlossene Windung mehr darstellt. Bei den bekannten Ausführungen ist die isolierende Zwischenlage in den durch den Rah-. men gelegten Schlitz eingepreßt und befestigt, wodurch jedoch die mechanische Festigkeit des Rahmens verringert wird.Built-in motor with a stator core, the bearing of the motor shaft and the brush holder supporting frames are built-in motors in many ways designed that the stator core is non-magnetizable from a frame Metal is worn, which is the bearing for the motor shaft as well as the brush holder wearing. In order to achieve a good mechanical structure, the frame is expedient inside the laminated core, so that .er a short-circuited turn in that of represents the field generated by the stator winding. With a stator core of less axial dimensions are relatively small due to this short-circuit winding Causes disadvantages. However, if the stator core has a greater axial length, so the electricity heat losses caused by the frame are already greater Meaning. In order to reduce these losses, it has already been proposed that Do not form the frame completely closed, but a cut at one point to lay through its cross-section, which is bridged by intermediate layers of insulating material so that the frame is no longer a closed turn. With the known Executions is the insulating intermediate layer in the through the frame. men laid Pressed and fastened slot, which, however, reduces the mechanical strength of the Frame is reduced.
Gemäß der Erfindung wird die isolierende Zwischenlage in solcher Weise mit dem Rahmen befestigt, daß durch diese die beiden durch die Trennfuge entstandenen Enden des Rahmens mechanisch gut miteinander verbunden werden. Der gemäß der Erfindung ausgebildete Rahmen hat daher nahezu die gleiche mechanische Festigkeit wie ein Rahmen ohne Trennfuge. In der Abbildung ist ein Ausführungsbeispiel, der Erfindung dargestellt. i i ist der aus unmagnetisierbarem Metall, wie Zink, Aluminium o. dgl., bestehende Rahmen, auf den das Ständerblechpaket 12 geschoben ist. Dieses ist an den Ansätzen 13 des Rahmens 11 befestigt. Der Motorläufer 14 ist in den in dem Rahmen i i angeordneten Lagern 1,5 gelagert, die Bürsten sind meinem unter Zwischenschaltung einer isolierenden Hülse 17 in dem Rahmen i i befestigten Rohr 18 in bekannter Weise geführt. Der Rahmen i i ist mit einem Schlitz ig versehen, durch den die von dem Rahmen i i gebildete Kurzschlußwindung unterbrochen ist. Die beiden Enden 20 und 2i des Rahmens i i sind in der Trennfuge ig iil Richtung senkrecht zur Motorachse mit Bohrungen 2z und 23 versehen, in die eine isolierende Einlage 24 eingelegt ist, dieinfolge ihres annähernd 8-förmigen Querschnittes die beiden Enden 2o und- 2 1 des Rahmens mechanisch zusammenhält. so daß die mechanische Festigkeit des Rahmens trotz Anordnung der Trennfuge i9 kaum beeinträchtigt ist.According to the invention, the insulating intermediate layer is fastened to the frame in such a way that the two ends of the frame produced by the parting line are mechanically well connected to one another through this. The frame designed according to the invention therefore has almost the same mechanical strength as a frame without a parting line. In the figure, an embodiment of the invention is shown. ii is the frame made of non-magnetizable metal such as zinc, aluminum or the like, onto which the stator core 12 is pushed. This is attached to the lugs 13 of the frame 11. The motor rotor 14 is mounted in the bearings 1,5 arranged in the frame ii; the brushes are guided in a known manner in my tube 18, which is fixed in the frame ii with an insulating sleeve 17 interposed. The frame ii is provided with a slot ig through which the short-circuit winding formed by the frame ii is interrupted. The two ends 20 and 2i of the frame ii are provided in the parting line ig iil direction perpendicular to the motor axis with bores 2z and 23, in which an insulating insert 24 is inserted, which, due to their approximately 8-shaped cross-section, the two ends 2o and 2 1 of the frame holds together mechanically. so that the mechanical strength of the frame is hardly affected in spite of the arrangement of the parting line 19.
