Abstract

Die vorliegende Erfindung betrifft eine Motorspindel für eine Werkzeugmaschine, insbesondere eine Hochfrequenz-Motorspindel, mit einer Spindelwelle (12) sowie mit einem elektrischen Antriebsmotor (14), der einen radial von der Spindelwelle (12) angeordneten Statorkern (22) sowie eine Statorwicklung (24) aufweist. Die Statorwicklung (24) besitzt zumindest einen in Axialrichtung über den Statorkern (22) vorspringenden Wickelkopf (28, 30). Ferner weist die Motorspindel ein Kühlelement (34) auf, das über einen ersten flächigen kontakt (40) thermisch leitend mit dem Statorkern (22) verbunden ist. Die Erfindung ist dadurch gekennzeichnet, daß im Bereich des vorspringenden Wickelkopfes (28, 30) ein Koppelelement (50, 52) angeordnet ist, das zumindest einen weiteren Bestandteil (12, 20, 60) der Motorspindel mittels eines weiteren flächigen Kontaktes (58) thermisch mit dem Kühlelement (34) verkoppelt.
