  Einrichtung zum Anlassen von Synchronmotoren. 



   Es ist bereits bekannt, ein   allmähliges   Anlaufen des Rotors von   Induktionsmotoren   ohne hohe   Anlaufstromstärke   unter Vermeidung von Anlassvorrichtungen dadurch anzustreben, dass man verschiedene Anker in den Stator der Motoren nacheinander hineinschiebt. Es ist auch nicht mehr neu, Synchronmotoren als Induktionsmotoren anzulassen.   Demgegenüber   besteht das Wesen der vorliegenden Erfindung darin, dass das Magnetrad des Synchronmotors hinter einem Blech-und einem Kurzschlussanker angeordnet ist und in den Stator geschoben wird, wenn der   Kurzschlussanker   die erforderliche Geschwindigkeit erreicht hat. 



   Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. 



   Der Stator des Motors ist mit a bezeichnet. b stellt einen wicklungsfreien Blechanker dar, g ist ein Kurzschlussanker und e das Magnetrad des Motors. Der so gebaute Rotor ist auf der Motorwelle vermittels einer geeigneten Vorrichtung selbsttätig oder von Hand verschiebbar. 



   Zum Anlassen des Motors wird der   Anker b   ins Innere des Stators a gebracht und der   Statorstrom   geschlossen. Der aufgenommene Strom wird in seiner Stärke ungefähr der des   Leerlaufbtromes   des Motors entsprechen. 



   Verschiebt man nun den Rotor in der Richtung des Pfeiles, so tritt der Anker b aus dem Stator a heraus und der Kurzschlussanker g tritt an dessen Stelle0 Die Stromstärke erhöht sich dabei ungefähr proportional mit der Anzugskraft. 



   Hat der Motor seine höchste Geschwindigkeit erreicht, so wird das Magnetrad e mit Gleichstrom erregt und der Rotor weiter verschoben, bis sich das Magnetrad vollständig im Innern des Stators befindet. Der Motor läuft dann als   Synchronmotor   weiter.

  Device for starting synchronous motors.



   It is already known to aim for a gradual start-up of the rotor of induction motors without a high starting current intensity by avoiding starting devices by pushing different armatures into the stator of the motors one after the other. It is also no longer new to start synchronous motors as induction motors. In contrast, the essence of the present invention is that the magnet wheel of the synchronous motor is arranged behind a sheet metal armature and a short-circuit armature and is pushed into the stator when the short-circuit armature has reached the required speed.



   An embodiment of the invention is shown in the drawing.



   The stator of the motor is labeled a. b represents a winding-free sheet metal armature, g is a short-circuit armature and e is the magnet wheel of the motor. The rotor constructed in this way can be moved automatically or by hand on the motor shaft by means of a suitable device.



   To start the engine, the armature b is brought into the interior of the stator a and the stator current is closed. The strength of the current drawn will roughly correspond to that of the no-load current of the motor.



   If you move the rotor in the direction of the arrow, the armature b emerges from the stator a and the short-circuit armature g takes its place. The current strength increases roughly proportionally with the tightening force.



   When the motor has reached its highest speed, the magnet wheel e is excited with direct current and the rotor is shifted further until the magnet wheel is completely inside the stator. The motor then continues to run as a synchronous motor.
