Description

Die Erfindung betrifft eine Einrichtung zur Luftumwälzung für geschlossene Elektromotoren, bei denen der Läufer mit etwa axialen Luftdurchtrittskanälen versehen ist und die Innenluft des Motors durch an beiden Enden des Läufers angebrachte Schaufeln, Lüfterflügel od. dgl. durch die Läuferkanäle und durch zwischen dem Ständerrücken und dem Motorgehäuse befindliche Zwischenräume im Kreislauf hindurchgetrieben wird. Im folgenden wird eine besonders einfache und vorteilhafte Einrichtung zur Erzielung des zur Wärmeabführung dienenden Luftkreislaufes im Innern des Motors gezeigt.The invention relates to a device for air circulation for closed Electric motors in which the rotor is provided with approximately axial air ducts and the internal air of the engine through blades attached to both ends of the rotor, Fan blades or the like through the rotor channels and through between the stator backs and gaps located in the motor housing are driven therethrough in the circuit. The following is a particularly simple and advantageous device for achieving of the air circuit used for heat dissipation inside the motor is shown.

Erfindungsgemäß sind zu diesem Zweck aus den Endblechen des Läufers schaufelartige, vor den Öffnungen der Läuferkanäle liegende Vorsprünge herausgedrückt. Es wird auf diese Weise die Anordnung besonderer Lüfterschaufeln gespart, und es ist auch kein besonderer Werkstoff für diesen Zweck erforderlich.According to the invention are for this purpose from the end plates of the rotor Shovel-like projections lying in front of the openings in the rotor channels are pressed out. In this way the arrangement of special fan blades is saved, and it no special material is required for this purpose either.

Die Fig. I und 2 der Zeichnung zeigen ein Ausführungsbeispiel eines gemäß der Erfindung ausgebildeten Läuferendbleches im Grundriß und im Querschnitt. Wie man aus der Zeichnung ersieht, sind hier die Schaufeln in Gestalt von taschenartigen Vorsprüngen 21 aus dem Endblech herausgedrückt. Es ist also kein besonderes Material für die Herstellung der Schaufeln und keinerlei Arbeit zur Anbringung derselben erforderlich.Figs. I and 2 of the drawing show an embodiment of a formed according to the invention rotor end plate in plan and in cross section. As you can see from the drawing, the blades here are in the shape of pocket-like ones Projections 21 pushed out of the end plate. So it's not a special material for making the blades and no work to attach them necessary.
