Description

Kleiner elektrischer Äußenläufermotor Die Erfindung bezieht sich auf einen elektrischen Außenläufermotor mit einer im Blechpaket des Innenständers für die Lagerung des glockenförmigen Außenläufers angeordneten Lager-hülse, welche an ihrem einen Ende mit Einrichtungen zur Befestigung des Rotors am Motorträger versehen ist, wobei der Ständer des Motors über mindestens ein federndes Zwischenglied drehelastisch an den Motorträger angekoppelt ist, nach Patent 1 291 824.Small external rotor electric motor The invention relates to an electric external rotor motor with one in the core of the inner stator for the bearing of the bell-shaped external rotor arranged bearing sleeve, which at one end of which is provided with means for fastening the rotor to the motor mount is, wherein the stator of the motor is torsionally elastic via at least one resilient intermediate member is coupled to the engine mount, according to patent 1,291,824.

Der nach der DT-PS 1 291 824 bekannte Motor weist den Nachteil auf, daß die federnden Zwischenglieder gegen radial an der Rotorwelle angreifende Belastungen, beispielsweise durch einen Riementrieb, zu nachgiebig sind.The motor known from DT-PS 1 291 824 has the disadvantage that the resilient intermediate members against loads acting radially on the rotor shaft, for example by a belt drive, are too flexible.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den Motor der eingangs genannten Art so zu gestalten, daß bei guter Entkopplung er Störschwingungen des Motors vom Hotorträger die auslenkungsfreie Lage der Motorwelle relativ zum Motorträger gewährleistet ist.The invention is therefore based on the object of the engine named type so that with good decoupling he spurious vibrations of the Motors from Hotorträger the deflection-free position of the motor shaft relative to the motor support is guaranteed.

Deshalb wird vorgeschlagen, daß die federnden Zwischenglieder zwischen dem Innenständer und der lager-hülse @ngeordnet sind und daß der Innenständer drehbar auf der Lager-hälse gelagert ist.It is therefore proposed that the resilient intermediate members between the inner stand and the bearing sleeve @ are arranged and that the inner stand is rotatable on the bearing neck is mounted.

Weitere vorteilhafte Merkmale der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous features of the invention are set out in the subclaims marked.

Die Erfindung wird anhand eines in der Zeichnung lasgestellten vorteijaften Ausführungsbeispiels erläutert.The invention is based on an advantage shown in the drawing Embodiment explained.

Die Fig. zeigt einen Längs schnitt durch den Stringer eine erfindungsgemciß gestalteten Motors.The figure shows a longitudinal section through the stringer according to the invention designed engine.

Auf dem Lagerträger 1 ist der nicht dargestellte Außenläufer gelagert. Gleichzeitig dient der Lagerträger 1 als Aufnahinedorn flir das Ständerblechpaket 2, zwischen dessen Innenbohrung a und der auf dem Lagerträger 1 gleitfähigen Buchse 4 eine gummielastische, höherfrequente Radialschwingungen dämpfende Zwischenschicht 5 angeordnet ist. Das Ständerblechpaket 2 ist mit der Wicklung 6 versehen. Der sich erweiternde Ansatz der Buchse 4 trägt axialverlaufende Stifte 7, welche druckknopfartig und axialfixierend in das mit dem Flansch 8 des Lagerträgers 1 verbundene gummielastische Element 9 eingreifen. Derart kann das Ständerblechpaket 2 als Quelle der Störschwingungen relativ zum Lagerträger 1 weich in tangentialer Richtung schwingen, so daß beispielsweise durch Pendelmomente erzeugte Störschwingungen des Ständerblechpakets 1 vom nicht dargestellten Gerät entkoppelt werden. Andererseits kann der Flansch 8 des Lagerträgers 1 starr mit dem nicht dargestellten Motorträger verbunden werden, so daß eine unauslenkbare Lage der Notorwelle gesichert ist.The external rotor, not shown, is mounted on the bearing bracket 1. At the same time, the bearing bracket 1 serves as a receiving mandrel for the stator core 2, between its inner bore a and the bushing that can slide on the bearing bracket 1 4 a rubber-elastic, higher-frequency radial vibration damping intermediate layer 5 is arranged. The stator core 2 is provided with the winding 6. Which widening approach of the socket 4 carries axially extending pins 7, which like a push button and axially fixing in the rubber-elastic connected to the flange 8 of the bearing bracket 1 Engage element 9. In this way, the stator core 2 can act as the source of the parasitic vibrations swing relative to the bearing bracket 1 soft in the tangential direction, so that, for example Interfering vibrations of the stator core 1 generated by pendulum moments from not device shown can be decoupled. On the other hand, the flange 8 of the bearing bracket 1 can be rigidly connected to the motor mount, not shown, so that a non-deflectable Position of the notor shaft is secured.
