KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen Steuerapparat für Drehstrom-Kollektormotoren, die mittels Bürstenverschiebung in ihrer Geschwindigkeit geregelt und umgesteuert werden. Wie bekannt, ist es bei derartigen Motoren vorteilhaft, gleichzeitig mit der Änderung der Drehrichtung des Ankers den Drehsinn des umlaufenden Drehfeldes zu wechseln. Um dieser Bedingung, nachzukommen kann man mit demThe invention relates to a control apparatus for three-phase collector motors, which by means of Brush displacement can be regulated and reversed in speed. As known, it is advantageous in such motors to change the direction of rotation at the same time of the armature to change the direction of rotation of the rotating field. To meet this requirement, you can use the
ίο Steuerorgan, welches die Bürstenfläche des Motors verschiebt, einen Umschalter konstruktiv verbinden, der bei der Geschwindigkeitsregelung unbeeinflußt bleibt, bei der Umschaltung des Steuerorganes für verschiedene Drehrichtungen jedoch zwei Phasen der Primärwicklung des Motors vertauscht.ίο control unit, which controls the brush surface of the Motor moves, constructively connect a changeover switch that controls the speed remains unaffected when switching over the control element for different directions of rotation however, two phases of the primary winding of the motor are reversed.
Gemäß vorliegender Erfindung wird aber die mechanische Umsteuerung mittels Handhebels o. dgl. vollständig getrennt von dem Umschalter, der die zwei Phasen des Primärankers umschalten soll. Man erhält nunmehr für die Verschiebung der Bürstenfläche einen einfachen Handhebel und für die Umschaltung der Primärwicklung einen normalen Umschalter, der von dem Motor selbst zweckmäßig mittels Anschläge im Augenblick der Drehrichtungsänderung herumgeworfen werden kann. Es ist jedoch auch möglich, den Umschalter elektrisch zu betätigen, etwa in der Art, wie dies in der Figur dargestellt ist. In dieser ist mit der Rotorwelle des Motors ein kleiner Hilfsgenerator g gekuppelt, der auf einen Motor m arbeitet. Letzterer ist mit dem Umschalter für die Phasenwicklung unmittelbar gekuppelt.According to the present invention, however, the mechanical reversal by means of a hand lever or the like is completely separate from the changeover switch which is to switch the two phases of the primary armature. A simple hand lever is now obtained for moving the brush surface and a normal changeover switch for switching the primary winding, which the motor itself can expediently toss around by means of stops at the moment of the change in direction of rotation. However, it is also possible to operate the changeover switch electrically, for example in the manner shown in the figure. In this a small auxiliary generator g is coupled to the rotor shaft of the motor, which works on a motor m . The latter is directly coupled to the changeover switch for the phase winding.
Da der Generator g fremderregt ist, wird seine Stromrichtung bei Umkehrung der Drehrichtung sich ebenfalls umkehren und den Motor m nach der einen oder anderen Richtung zu drehen suchen und somit den Schalter in der einen oder anderen Richtung umlegen. Natürlich können an Stelle von Gleichstromhilfsmaschinen auch z. B. Drehstrommaschinen verwendet werden.Since the generator g is externally excited, its current direction will also reverse when the direction of rotation is reversed and the motor m will seek to turn in one direction or the other and thus flip the switch in one direction or the other. Of course, instead of DC auxiliary machines, z. B. three-phase machines are used.
Innerhalb der für die Geschwindigkeitsregelung des Hauptmotors in Frage kommenden 4^ Bürstenstellung wird natürlich der Umschalter nicht beeinflußt.The changeover switch is of course not influenced within the 4 ^ brush position in question for regulating the speed of the main motor.
Es ergibt sich hieraus der wesentliche Vorteil, daß der eigentliche, dem Bedienungsmann in die Hand zu gebende Steuerapparat der denkbar einfachste wird, da mit ihm keinerlei zu betätigende Kontakte usw. verbunden zu werden brauchen. Er verträgt daher unsachgemäße Behandlung und mangelhafte Wartung ohne weiteres, während der schon etwas empfindlichere Phasenumschalter mit dem Elektromotor ein einheitliches Ganzes bildet und staub- und spritzwasserdicht eingekapselt werden kann.This results in the essential advantage that the actual, the operator The control apparatus to be put into the hand is the simplest imaginable, since it does not involve any to be operated contacts etc. need to be connected. It can therefore tolerate improper handling and poor maintenance without further ado, while the somewhat more sensitive phase switch with the electric motor forms a unified whole and can be encapsulated dust-proof and splash-proof.
