 des Motors a ist also dabei kurzgeschlossen. Wird das obere Relais p erregt, so zieht es seinen Anker gegen den unteren Kontakt und legt damit die untere Bürste des Motors a all das obere Ende des Widerstandes t. Der Anker erhält dadurch Spannung und läuft in einer bestimmten 
 EMI5.2 
 des Widerstandes t verbundenen Kontakt gezogen ; dabei erhält der Anker wieder Strom, aber jetzt mit der entgegengesetzten Richtung wie vorher. Der Motor läuft deshalb auch in der 
 EMI5.3 
 der Motor   ff   bei seiner Bewegung von den Enden des Vorschaltwiderstandes t gespeist wird. 



  Da die gegenelektromotorische Kraft des Motors a beim Anlauf Null ist und erst   allmählich   auf einen höheren Wert steigt, so kann man den Widerstand t im Augenblick des anlaufs als kurzgeschlossen ansehen. Die   Mehrphasenströme   erzeugen demnach in diesem Augenblick ihre 
 EMI5.4 
 die   Synchronmotoren   s sich ihrer Höchstdrehzahl nähern. Beim stufenweisen Anlassen des Motors a kann der Vorschaltwiderstand t gleichzeitig als Aulasswiderstand verwendet werden. 



   Benutzt man zur Übertragung der wagerechten oder   lotrechten Bewegung einen ge-     meinsamen Widerstand für die Spannungsteiler   oder auch einen gemeinsamen Kollektor, so kann man die Antriebsmotoren für die Bürsten parallel an einen gemeinsamen   Vorschaltwiierstaland   anschliessen oder auch   getrennte   Vorschaltwiderstände in Serie schalten und sie so bemessen, dass bei Kurzschluss nur eines einzigen Widerstandes der Mehrphasenstrom eine genügende   Stärke erhält.

 EMI5.1
 of the motor a is thus short-circuited. When the upper relay p is energized, it pulls its armature against the lower contact and thus places the lower brush of the motor a all the upper end of the resistor t. The anchor receives tension and runs in a certain
 EMI5.2
 of the resistor t connected contact pulled; the armature receives electricity again, but now in the opposite direction as before. The engine therefore also runs in the
 EMI5.3
 the motor ff is fed during its movement from the ends of the series resistor t.



  Since the counter-electromotive force of the motor a is zero at start-up and only gradually increases to a higher value, the resistance t can be viewed as short-circuited at the moment of start-up. The multiphase currents therefore generate theirs at this moment
 EMI5.4
 the synchronous motors s approach their maximum speed. When the motor a is started in stages, the series resistor t can be used as an outlet resistor at the same time.



   If a common resistor for the voltage divider or a common collector is used to transmit the horizontal or vertical movement, the drive motors for the brushes can be connected in parallel to a common ballast or separate ballast resistors can be connected in series and dimensioned so that in the event of a short-circuit of only one single resistor, the multiphase current is sufficiently strong.
