Description
Elektrische Antriebsmaschine aus zwei zu einer lösbaren Einheit verbundenen, auf die gleiche Abtriebswelle arbeitenden Verschiebeläufermotoren ungleicher Leistung In der Hauptpatentanmeldung ist eine elektrische Antriebsmaschine vorgeschlagen, die aus zwei zu einer lösbaren Baueinheit verbundenen, auf die gleiche Abtriebswelle arbeitenden Verschiebeläufermotoren ungleicher Leistung besteht. Dabei ist bei Anwendung von Verschiebeläufermotoren üblicher Bauart an Stelle des die Bremse umschließenden Gehäuseteiles des einen Motors ein als Träger für den anderen Motor dienender, ebenfalls die Bremse umschließender topfartiger Teil angeschlossen.Electric drive machine from two connected to form a detachable unit, Displacement rotor motors of unequal power working on the same output shaft In the main patent application, an electric drive machine is proposed, the two connected to a detachable unit, on the same output shaft working displacement rotor motors of unequal power. It is with application of sliding rotor motors of the usual design instead of the one surrounding the brake Housing part of one motor serving as a support for the other motor, too the brake enclosing cup-like part connected.
Es sind zwar bereits Verschiebeankermotoren mit Schleifringankern bekanntgeworden, doch werden sie im allgemeinen als Kurzschlußläufermotoren ausgebildet, die aber den Nachteil eines hohen Anlaufstromes aufweisen. Wird daher eine Antriebsmaschine der in der Hauptpatentanmeldung gekennzeichneten Art unter Verwendung von Kurzschlußläufermotoren dort eingesetzt, wo hohe Leistungen erforderlich sind, wie beispielsweise bei einem Kranantrieb, dann würde beim Einschalten der Motoren, insbesondere des Motors mit der höheren Leistung, das Stromnetz unerwünscht hoch belastet.There are already sliding armature motors with slip ring armatures became known, but they are generally designed as squirrel cage motors, but which have the disadvantage of a high starting current. Therefore it becomes a prime mover of the type identified in the main patent application using squirrel cage motors Used where high performance is required, such as a Crane drive, then when switching on the motors, especially the motor with the higher power, the power grid is undesirably heavily loaded.
Die Erfindung schlägt daher vor, für solche Fälle den Motor höherer Leistung als Schleifringläufermotor auszubilden, der über Vorschaltwiderstände allmählich angelassen werden kann. Auf diese Weise wird eine Überlastung des Stromnetzes mit Sicherheit vermieden, und es ergibt sich darüber hinaus die Möglichkeit, die zu bewegenden Massen allmählich zu beschleunigen, was z. B. bei einem Krandrehwerk zur Vermeidung von Pendelbewegungen der Last wichtig ist.The invention therefore proposes that the motor be higher for such cases Train power as a slip ring motor, which gradually over series resistors can be started. This way there will be an overload of the power grid with Avoided security, and there is also the possibility of that too moving masses to gradually accelerate what z. B. in a crane slewing gear is important to avoid pendulum movements of the load.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Schnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in section.
An das Gehäuse eines mit einem Wellenstumpf versehenen, als Schleifringläufermotor ausgebildeten Verschiebeankermotors 1 ist ein topfartiges Gehäuseteil 2 angeflanscht, das wiederum als Träger für den Kurzschlußläufermotor 3 dient. Zwischen beiden Motoren ist das auf dem Schild 4 des Motors 3 gelagerte Getriebe 5 vorgesehen, dessen - in Richtung des Kraftflusses vom Motor 3 zum Motor 1 betrachtet - letztes Glied mit dem Bremsring 6 der Bremse des Motors 1 verbunden ist, so daß er mit diesem Getriebeteil umzulaufen vermag. Wird der Motor 1 eingeschaltet, dann wird die Verbindung zum Getriebe und damit zum Motor 3 gelöst. Wird hingegen der- Motor 3 eingeschaltet, dann wird dessen Bremse 7 gelüftet und sein Drehmoment über das Getriebe 5, den Bremsring 6 und die Bremsscheibe 8 auf die Welle des Motors 1 übertragen. Die Abbremsung der Antriebsmaschine erfolgt in jedem Falle durch die Bremse 7 des Motors 3.On the housing of a slip ring motor with a stub shaft trained sliding armature motor 1 is a pot-like housing part 2 flanged, which in turn serves as a carrier for the squirrel cage motor 3. Between the two engines the gear 5 mounted on the shield 4 of the motor 3 is provided, the - viewed in the direction of the power flow from motor 3 to motor 1 - last link is connected to the brake ring 6 of the brake of the motor 1, so that it is with this Gear part is able to revolve. When motor 1 is switched on, the connection is established to the transmission and thus to the engine 3 solved. If, however, the motor 3 is switched on, then the brake 7 is released and its torque via the transmission 5, the Transfer the brake ring 6 and the brake disc 8 to the shaft of the motor 1. The deceleration of the prime mover is effected in each case by the brake 7 of the motor 3.
