Description

Einrichtung zum Umkehren der Drehrichtung von Kommutatormotoren Es ist bekannt, die Drehrichtung von Kommutatormotoren,durchentsprechende Kontaktvorrichtungen und Bürstrenverstellung umzukehren und gleichzeitig zu erreichen, daß das Querfeld des, Ankers bei beiden Drehrichtungen möglichst kompensiert wird.Device for reversing the direction of rotation of commutator motors Es is known, the direction of rotation of commutator motors, through appropriate contact devices and reverse brush adjustment while achieving that cross field des, armature is compensated as far as possible in both directions of rotation.

Die Handhabung derartiger Umkehrvorrichtuggen ist für den Nichtfachmann umständlich. Die Umkehrvorrichtung gemäß der Erfindung macht die Kontaktvorrchtungen und die Bürstenverschiebung überflüssig und kann auch vom Laien leicht bedient werden.The handling of such inverters is for the non-skilled person laborious. The reversing device according to the invention makes the contact devices and the brush shift is superfluous and can also be easily operated by laypeople.

Die Erfimdun@g besteht darin, daß für die beiden. Drehrichtungen gemeinsame Wicklungen und zwei ,gegenüber der neutralen Zone feststehende Bürstenhalterpaare mit nur einem wirksamen Bürstenpaar angeordnet sind.The invention consists in that for the two. Directions of rotation common Windings and two pairs of brush holders fixed in relation to the neutral zone are arranged with only one effective pair of brushes.

Abb. i zeigt schematisch @di:e neue Reversiervorri:chtung. f stellt die Feldwicklung des Reihenschlußkommutatormotors dar, während a a1 und' b b1 die beiden Bürstenhalterpaare bedeuten. Hierbei sind jeweils die gleichpoligen Bürstenhalter a b bzw. ,a1 b1 elektrisch miteinander verbunden. Je nachdem, tib die Bürsten des, Bürstenhalterpaares a a1 .oder jene des Bürstenhalterpaares b bl aufliegen, resultiert eine bestimmte Stromrichtunig im Anker und eine besümmte Drehrichtung des- Motors, wie aus den beiden Abb. z und 3 eirkannt werden kann. ` Das Bürsitenhalterpaar b b1 ist unter dem Winkel + a, das Bürstenhalterpaar a a1 .unter dem Winkel - a zur neutralen Achse angeordnet, wobei a ,so gewählt ist, daß das Querfeld des Ankers bei beiden Drehrichtungen: ganz oder teilweise kompensiert wird.Fig. I shows a schematic of the new reversing device. f represents the field winding of the series commutator motor, while a a1 and ' b b1 mean the two pairs of brush holders. Here, the homopolar brush holders a b and a1 b1 are electrically connected to one another. Depending on whether the brushes of the pair of brush holders a a1 or those of the pair of brush holders b bl are resting, the result is a certain current direction in the armature and a specific direction of rotation of the motor, as can be seen from the two figures z and 3. `The pair of brush holders b b1 is arranged at the angle + a, the pair of brush holders a a1 at the angle - a to the neutral axis, where a is chosen so that the transverse field of the armature is fully or partially compensated for in both directions of rotation.

Erfindungsgemäß werden nur in zwei gegenüberliegend'en Bürstenhaltern, z. B. rc a1, zwei Bürsten eingesetzt (Abb.3) und zur Umkehrung der Drehnichtung diese beiden @ürsten herausgenommen und 'm den beiden anderen Bürstenhaltern b b1 eingesetzt (Abb. z). Die konstruktive Ausbildung der Erfindung wird besonders einfach, wenn man die beiden Bürsteuhalterpaare in entsprechenden Bohrungen des Lagerschildes ,anordnet. Praktisch, versieht man: das Lagerschild an den Stellen, wo das wirksame .Bürstenpaar- sitzt, mit Pfeilen, welche die diesem Bürstenpaar ,entsprechende Drehrichtung angeben, wie aus den Abb. q. und 5, welche ein Lagerschild mit eingesetzten Bürstenhalliern in An- und Draufsicht zeigen, zu ersehen ist.According to the invention, only two brush holders opposite one another, e.g. B. rc a1, two brushes inserted (Fig. 3) and to reverse the direction of rotation these two brushes removed and inserted into the other two brush holders b b1 (Fig. Z). The structural design of the invention is particularly simple if the two pairs of Bürsteuhalterpaars are arranged in corresponding bores in the end shield. Practically, one provides: the bearing shield at the points where the effective .Bürstenpaar- sits, with arrows, which indicate the direction of rotation of this pair of brushes, as shown in Fig. Q. and FIG. 5, which shows a bearing plate with inserted brush shells in perspective and plan view, can be seen.
