Doppelmotor, bestehend aus einem Induktionsmotorenteil und einem ReihenschlußmotorenteilDouble motor, consisting of an induction motor part and a series motor part

Die Erfindung betrifft einen Doppelmotor, der aus einem Induktionsmotorenteil und aus einem Reihenschlußmotorenteil besteht und der insbesondere als Antrieb für eine Waschmaschine dient.The invention relates to a double motor consisting of an induction motor part and consists of a series motor part and which serves in particular as a drive for a washing machine.

Doppelmotoren der vorstehenden Art werden häufig als Antrieb in Waschmaschinen eingesetzt, da sich mit diesen Motoren in vorteilhafter Weise der für das Waschprogramm notwendige Drehzahlbereich überdecken läßt. Dabei dient der Induktionsmotorenteil zum Antrieb der Maschine im Waschgang, während im Schleudergang der auf gleicher Welle sitzende Reihenschlußmotorenteil für den Antrieb sorgt.Double motors of the above type are often used as a drive used in washing machines, since these motors advantageously allow the speed range required for the washing program can be covered. The induction motor part is used to drive the machine in the wash cycle while in the spin cycle the series motor part on the same shaft provides the drive.

Bei diesen Motoren hat sich jedoch der Nachteil gezeigt, daß bei Waschbetrieb, wenn die Wäschetrommel durch den Induktionsmotor angetrieben wird, der stromlos mitlaufende Reihenschlußmotor Störgeräusche hervorruft. Die auf dem Kollektor im stromlosen Kontakt schleifenden Bürsten des Motors, sind die Ursache für die störenden Quietschgeräusche.In these motors, however, the disadvantage has been shown that in washing operation, when the laundry drum by the induction motor is driven, the de-energized series-wound motor causes disturbing noises. The one on the collector in the de-energized Contact with the brushes of the motor, are the cause of the annoying squeaking noises.

Die Aufgabe der Erfindung ist es, einen Doppelmotor, insbesondere für den Antrieb einer Waschmaschine zu offenbaren, bei dem auf einfache Weise die vorerwähnten Störgeräusche vermieden werden.The object of the invention is to disclose a double motor, in particular for driving a washing machine, in which the aforementioned interference can be avoided in a simple manner.

Zu diesem Zweck ist die Erfindung dadurch gekennzeichnet, daß die Bürstenhalter für die Bürsten des Reihenschlußmotors in einem elastischen Teil angeordnet sind.For this purpose, the invention is characterized in that the brush holders for the brushes of the series motor in an elastic part are arranged.

In einer vorteilhaften Ausgestaltung besteht das elastische Teil aus Silikon-Kautschuk.In an advantageous embodiment, there is the elastic Part made of silicone rubber.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing.

Die einzige Zeichnung zeigt ausschnittsweise die Bürstenhalterung des Reihenschlußmotors im Schnitt.The only drawing shows a section of the brush holder of the series motor in section.

Die Bürste 1 ist in dem Bürstenhalter 2 mittels der Klemmfedern 3 federnd geführt und gehalten.The brush 1 is resiliently guided and held in the brush holder 2 by means of the clamping springs 3.

Die Bürstenandruckfeder U drückt die Bürste 1 auf den Kollektor 5.The brush pressure spring U presses the brush 1 onto the collector 5.

Der Bürstenhalter 2 ist in dem elastischen Teil 6 gelagert. Dieses Teil 6 kann beispielsweise aus Silikon-Kautschuk bestehen. The brush holder 2 is mounted in the elastic part 6. This part 6 can for example consist of silicone rubber.

Über geeignete Befestigungsmittel 7, z.B. mittels einer Schelle, kann die gesamte Bürstenhaltevorrichtung am Lagerschild des Motors befestigt sein.The entire brush holding device can be attached to the end shield by means of suitable fastening means 7, for example by means of a clamp of the motor.

Es hat sich gezeigt, daß durch die erfindungsgemäße Lagerung des Bürstenhalters, die störenden Geräusche beim stromlosen Mitlaufen des Reihenschlußmotors weitgehendst vermieden werden.It has been shown that the storage according to the invention of the brush holder, the annoying noises when the series motor is running without current can be largely avoided.
