   selbe durch dm Stellung   des Schalters e auf IV und die bei der gleichen Bewegung des Hebels i auf   I'ei folgende Umstellung   des Schalters f auf I der Stromkreis für die Magnete l und k bei 5   unterbrochen tst,   sobald die Überbrückungsschaltung bei 14 aufgehoben wird. Es ist somit die   erwinschte Sicheiheit   der richtigen Drehfeldrichtung in vollkommenem Masse erreicht. 



     Kg   wird deshalb die Sicherheitsbremse die Maschine stillsetzen, sobald dieselbe   mit. etwas   kleinerer Geschwindigkeit, welche durch die Einstellung des Zentrifugalschalters gegeben ist, entgegen dem vorher eingestellten Drehsmme des Feldes angelassen wird. Umgekehrt wird hiedurch auch bei vorangehender Emstellung des Drehrichtungsumschalters im Sinne der beabsichtigten   Drehrichtung des Motors die selbsttätige Stillsetzung der Maschine erfolgen, sobald infolge     unrichtigen Auslegens des Hebels @ die Maschine   in falscher Drehrichtung in Bewegung gesetzt wird. 



    PATENT-ANSPRÜCHE:     l.     1mrichtung     zui Verhinderung einer unrichtigen Drehfeldschaltung   bei   DrehfeldkoUektor-   motoren, dadurch gekennzeichnet, dass die Umschaltung des Drehfeldes solange gesperrt bleibt, als der Drehsinn des Motors der vorhandenen Drehfeldrichtung und somit   Drehfeldschalter-   stellung entspricht.

 EMI2.1
 broken and thus the movement of the lever c completely unhindered. The tripping magnet 1, on the other hand, receives from 1 to 14 and 8 at standstill and at low speeds
 EMI2.2
   the same by the position of switch e to IV and the switching of switch f to I following the same movement of lever i to I'ei, the circuit for magnets l and k at 5 is interrupted as soon as the bridging circuit at 14 is canceled. The desired certainty of the correct rotating field direction is thus fully achieved.



     Kg, the safety brake will stop the machine as soon as the same with. slightly lower speed, which is given by the setting of the centrifugal switch, is started against the previously set Drehsmme of the field. Conversely, even if the direction of rotation switch was previously set in the sense of the intended direction of rotation of the motor, the machine will automatically shut down as soon as the machine is set in motion in the wrong direction of rotation as a result of incorrectly interpreting the lever @.



    PATENT CLAIMS: l. 1mrichtung zui Prevention of incorrect rotary field switching in rotary field coUector motors, characterized in that the switching of the rotary field remains blocked as long as the direction of rotation of the motor corresponds to the existing rotary field direction and thus the rotary field switch position.
