 EMI2.1 
 



   Als Motoren,   die'den. dargestellten Bedingungen genügen, können nach   der Erfindung Drehstromkollektormotoren Verwendung finden. Es ist jedoch auch möglich, Asynchronmotoren mit Läuferregelung zu verwenden, wenn nach der Erfindung in den Läuferkreis   Mindestwiderstände eingeschaltet   
 EMI2.2 
 



   Anstatt den Vorschub durch Veränderung des regelbaren Läuferwiderstandes zu regeln, kann man in bekannter Weise auch die dem Vorschubmotor oder den Vorschubmotoren zugeführte Spannung ändern, z. B. durch einen Drehtransformator oder durch einen angezapften Spannungswandler. Diese Art der Regelung lässt sich auch bei Drehstromkollektormotoren   durchführen.   Auch mit dieser Art der

PATENT-ANSPRÜCHE :   1. Elektrischer Drehstromantrieb für die Vorschubvorrichtung an Holzschleifern, gekennzeichnet durch die Verwendung : von Drehstrommotoren, deren Drehmoment vom Stillstand bis zur höchsten Vor-   schubgesehwindigkeit ständig abnimmt, so dass die Vorschubgeschwindigkeit in Abhängigkeit von der
Belastung des Schleifers, aber elektrisch unabhängig vom Schleifermotor, selbsttätig geregelt wird.

 EMI2.1
 



   As engines that'den. Satisfy the conditions shown, three-phase collector motors can be used according to the invention. However, it is also possible to use asynchronous motors with rotor control if, according to the invention, minimum resistances are switched into the rotor circuit
 EMI2.2
 



   Instead of regulating the feed by changing the adjustable rotor resistance, you can also change the voltage supplied to the feed motor or the feed motors in a known manner, e.g. B. by a rotary transformer or by a tapped voltage converter. This type of control can also be carried out with three-phase collector motors. Even with this type of

PATENT CLAIMS: 1. Electric three-phase drive for the feed device on wood grinders, characterized by the use of: three-phase motors whose torque continuously decreases from standstill to the highest feed speed, so that the feed speed depends on the
Load on the grinder, but electrically independent of the grinder motor, is regulated automatically.

Claims (1)
