Das magnetilsierbare, pulverförmige Kupplungsmiedium besteht dabei vorzugsweise aus einem Carbonyleisenpulver mit: oder ohne Zusatzeines. oxydationsverhindernden. Mittels; z. B:. Ö1. Unter dein Einflut de"s Magnetfeldäs wird das. pulverförmige Kupplungsmedium fester und fester, wodurch ein, mehr und mehr wachsendes Drehmoment zwischen den Kupplungsteilen übertragen wird. Der umlaufenden Magnetspule wird; die Erregerleistung mittels Bürsten, und Schleifringe oder auf induktivem Wege übertragen.Electromagnetic clutches are known where the torque is low via a magneüisienba> r @ es located in the magnetic field; pwlverförrri, igess coupling medium. is transmitted. The magnetizable, powdery coupling medium consists of this preferably from a carbonyl iron powder with: or without the addition of one. anti-oxidation. Means; z. B: Ö1. Under your influence of the magnetic field it becomes powdery Clutch medium tighter and tighter, resulting in a more and more growing torque is transmitted between the coupling parts. The rotating solenoid is; transmit the excitation power by means of brushes and slip rings or inductively.
Die Erfindung bezieht sich auf eine Einrichtung zur Schaltung einer ,solchen Mägnetpulverkupplung in ihrer Anwendung als Anla,ßkupplung für elektri,srhe Antriebsmotoren, die mitteJs einer- besonderen Anlaßschaaltung angelassen, werden: Diie Erfindung besteht im wesentlichen darin, daß die Erregung der Magnetspule der Magnetpulverkupplung zwangsläufig mit der Anlaßschaftung des Motors verbunden ist, -und zwar derart, daß die Erregung der Spule erst mit der Umschaltung des Anlassers auf die Betriebsstellung eingeschaltet wird. Bei Verwendung einer Sterudreäeclschaltung als Anslaßs@cjhatltung.iis,t ,die Magnetspule der Magnetpulverkupplung während der Sternschaltung spannungslos, während sie bei :der betrieblichen Dreieckschaltung an voller Spannung liegt.The invention relates to a device for switching a , such magnetic powder coupling in its application as an Anla, ßkupplung for electrical, srhe Drive motors that are started in the middle of a special starter circuit are: The invention consists essentially in the fact that the excitation of the magnet coil Magnetic particle clutch is inevitably connected to the starting shaft of the engine, - in such a way that the coil is only excited when the starter is switched over is switched on to the operating position. When using a steroidal circuit als Anslaßs @ cjhatltung.iis, t, the magnetic coil of the magnetic particle clutch during the Star connection without voltage, while it is with: the operational delta connection is due to full tension.
Eine solche zwangsUuige Verbindung der Kupplnugsischaltung mit, der, Anlaß,schaltung des zugehörigen Motors hat den Vorteil, da.ß, die Kupplung immer erst dann zum Eingriff kommt, wenn der Mo1toT hochgelaufen ist. Der entlastete Arvlauf des Motors wird damit zwangsläufig gesichert.Such a compulsory connection of the clutch circuit with the, The starting circuit of the associated motor has the advantage that the clutch is always activated Intervention only takes place when the Mo1toT has started up. The relieved Arvlauf the motor is thus inevitably secured.
Die Zeichnung zeigt als Ausführungsbeispiel der Erfindung die Verbindung der Kupplungsscha:ltung mit der Sterndreieckschaltung eines Drrehstrommotors. io ist die Ständerwicklung des Drehstrommotors, die in üblicher Weise in Fig. i im Stern und in Fig. 2 im Dreieck geschaltet ist. Über zwei Phasen ist die Primärwicklung des Transformators i i angeschlossen, der die Netzspannung auf die niedrigere Erregungsspannung der Magnetspule der Kupplung umspannt. Die auf die Sekundärwicklung des Transformators: ii übertragene Wechselspannung wird durch denTrockengleichrchter 12 gleichgerichtet und dann als Gleichspannung der Magnetspule 13 der nicht gezeigten Maguebpulverkupplung zugeführt.The drawing shows the connection as an embodiment of the invention the coupling circuit with the star-delta connection of a three-phase motor. ok is the stator winding of the three-phase motor, which is shown in the usual manner in FIG Star and in Fig. 2 in delta. The primary winding is over two phases of the transformer i i connected, the line voltage to the lower excitation voltage the solenoid of the clutch spans. The ones on the secondary winding of the transformer: The transmitted AC voltage is rectified by the dry rectifier 12 and then as a DC voltage of the magnetic coil 13 of the magnetic powder clutch, not shown fed.
Die Zeichnung läi& erkennen; daß die Magnetspule 13 in der Sternschaltung der Fig. i spannungslos. ist, während -sie in der Dreieckschaltung der Fg. 2i an voller Spannung liegt, Die Kupplung kommt infolgedessen erst dann zum Eingriff, wenn der Motor in Sternschaltung hochgelaufen und auf die betriebliche Dreieckschaltung umgeschaltet ist. Der entlastete Anlaud des Motors ist damit zwangsläufig gesichert.The drawing läi &recognize; that the solenoid 13 in the star connection of Fig. i without tension. is, while -she in the delta connection of Fig. 2i on full tension, as a result the clutch only engages when when the motor has started up in star connection and on operational delta connection is switched. The relieved start-up of the engine is thus inevitably ensured.
