EMI1.1
Bei Repulsionsmotoren, etwa solchen, die als Repulsionsmotor anlaufen und. nach Erreichen einer gewissen Drehzahl als Induktionsmotor weiter laufen (z. B. bei Aufzugmotoren), ist es bekannt, zum Betriebe für beide Drehrichtungen im Stator ausser einer Haupt-(Kom- pensations-@ Wicklung G, H (Fig. I) noch zwei Hilfs-(Erreger)Wicklungen E, F1 unf E, F2 vorzusehen, wovon je nach der Drehrichtung die eine oder die andere durch einen Umschalter U eingeschaltet wird.
EMI1.2
ein hohes Drehmoment bei mässiger Stromaufnahme entwickelt. Es besteht das Bedürfnis. einen solchen Motor für ein bestimmtes Drehmoment oder einen zulässigen Anlaufstrom einstellen zu können.
Es ist bekannt, eine solche Einstellbarkeit dadurch zu ermöglichen, dass in den Rotorkreis ein veränderlicher Widerstand geschaltet wird (Fig. I). Diese Einstellbarkeit hat jedoch den Nachteil eines verhältnismässig hohen Stromverbrauches.
Erfindungsgemäss wird dieser Nachteil dadurch vermieden, dass die Stärke jedes der beiden Hilfsfelder mit Hilfe je eines mit der Haupt-Kompensations-)Wicklung G. H in Reihe liegenden Transformators. deren gemeinsamer Punkt O am Motorverkettungspunkte H, E liegt, durch Änderung von dessen Windungszahl eingestellt werden kann, also durch Verlegen
EMI1.3
sondern zwischen dem Punkte 5 eines Reihentransformators und den Punkten FI. F2 des Motors, so dass man mit einem einzigen Transformator auskommt.

EMI1.1
In repulsion motors, such as those that start as repulsion motors and. to continue running as an induction motor after a certain speed has been reached (e.g. in elevator motors), it is known to operate for both directions of rotation in the stator except for one main (compensation @ winding G, H (FIG. 1)) Auxiliary (exciter) windings E, F1 and E, F2 are to be provided, one or the other of which is switched on by a changeover switch U depending on the direction of rotation.
EMI1.2
develops high torque with moderate power consumption. There is a need. to be able to set such a motor for a certain torque or a permissible starting current.
It is known that such an adjustability can be made possible by switching a variable resistor into the rotor circuit (FIG. I). However, this adjustability has the disadvantage of a relatively high power consumption.
According to the invention, this disadvantage is avoided in that the strength of each of the two auxiliary fields with the help of a transformer in series with the main compensation) winding G. whose common point O is at the motor interlinking points H, E, can be set by changing the number of turns, i.e. by relocating
EMI1.3
but between point 5 of a series transformer and points FI. F2 of the motor, so that you can get by with a single transformer.
PATEXT-AX Slogans:
I. AC repulsion motor with auxiliary switchable for both directions of rotation
EMI1.4
variable number of turns are connected. for the purpose of being able to adjust the tightening torque and current consumption as required.
