Schaltungseinrichtung zur Regelung von Hauptetrommotoren mittel eines Im Nebenechlues zur Feldwloklung liegenden Regelungswiderstandes.
EMI1.1
dem Nebenschlusswiderstand eine besondere Drosselspule vorzuschalten. Die den Gegenstand der Erfindung bildende Einrichtung gestattet, den gleichen Zweck in sehr einfacher und billiger Weise zu erreichen.
Das Wesen der Erfindung besteht darin, dass der Regelungswiderstand nicht parallel zur ganzen Feldwicklung gelegt wird, sondern nur parallel zu einem Teil der Magnet windungen,
EMI1.2
ist der Regelungswiderstand w der Feldwicklung / parallel geschaltet und diese beiden zusammen mit den Windungen h und dem Anker a in Reihe geschaltet. Bei dem Ausführungsbeispiel nach Fig. 2 ist der Regelungswiderstand mit den Windungen h in Reihe geschaltet und beide zusammen liegen parallel zu den Windungen /. Es genügt hierbei, wenn die Windungen h nur etwa 100 () der Windungen / ausmachen.
Die Wirkungsweise dieser Anordnung beruht darauf, dass erstens infolge des induktiven Widerstandes der Feldwicklung h nicht mehr bei plötzlichen Stromstössen nahezu der ganze Strom durch den Regelungswiderstand fliesst und dass zweitens auch dieser Stromzweig zur Erzeugung des Feldes beiträgt. Ebenso wirkt auch bei der Anordnung nach Fig. l der durch den Widerstand fliessende Strom in den Windungen h felderzeugend.
Die Windungen h können auf sämtlichen oder bloss auf einzelnen Polen der Maschine angeordnet sein. Im letzteren Falle empfiehlt es sich, die Windungen h nicht etwa auf benach- barten, sondern auf diametral gegenüber liegenden Polen unterzubringen. Es wird so beispiels-

Circuit device for controlling main electric motors by means of a control resistor located in the secondary connection to the field cloud.
EMI1.1
to connect a special choke coil upstream of the shunt resistor. The device forming the subject of the invention makes it possible to achieve the same purpose in a very simple and inexpensive manner.
The essence of the invention is that the control resistor is not placed parallel to the entire field winding, but only parallel to part of the magnet windings,
EMI1.2
the control resistor w of the field winding / is connected in parallel and these two are connected in series together with the turns h and the armature a. In the embodiment according to FIG. 2, the control resistor is connected in series with the turns h and both are together parallel to the turns /. It is sufficient here if the turns h make up only about 100 () of the turns /.
The mode of operation of this arrangement is based on the fact that, due to the inductive resistance of the field winding h, almost all of the current no longer flows through the control resistor in the event of sudden current surges and that, secondly, this branch also contributes to the generation of the field. Likewise, in the arrangement according to FIG. 1, the current flowing through the resistor in the windings h also produces a field.
The turns h can be arranged on all or only on individual poles of the machine. In the latter case it is advisable not to place the turns h on adjacent poles, but on diametrically opposite poles. It will be so exemplary

Anchors avoided.
