Description
Herstellung des Läufers für elektrische Kurzschlußläufermotoren im Sinterverf ahren Es ist bereits vorgeschlagen worden, die Eisenkörper elektrischer Maschinen aus Eisenpulver, das gegebenenfalls zur Herabsetzung der Wirbelstromverluste mit geeignetem Isolierstoff, beispielsweise Kunstharz, gemischt ist, im Sinterverfahren herzustellen. Dabei ist nur daran gedacht worden, das bisher übliche Verfahren des Schiehtens des Eisenkörpers aus vorgestanzten Blechen durch das Sinterverfahren zu ersetzen. Die Weiterverarbeitung, insbesondere das Einbringen der Wicklungen, sollte auf üblichem Wege erfolgen.Manufacture of the rotor for electric squirrel cage motors in Sintering process It has already been proposed to make the iron body electrical Machines made of iron powder, which may be used to reduce eddy current losses is mixed with a suitable insulating material, for example synthetic resin, in the sintering process to manufacture. It has only been thought of using the previously common method of The iron body is made from pre-cut sheet metal using the sintering process to replace. The further processing, in particular the introduction of the windings, should be done in the usual way.
Gemäß der Erfindung kann das Sinterverfahren bei der Herstellung der Eisenkörper elektrischer Maschinen in vorteilhafter Weise dazu verwendet werden, die Herstellung der Läufer elektrischer Kurzschlußläufermotoren dadurch zu verbessern und zu vereinfachen, daß der vorher für sich auf beliebige Weise hergestellte Kurzschlußkäfig in den Läuferkörper bei der Sinterung mit eingebettet wird. Zu diesem Zweck wird also der Kurzschlußkäfig zunächst, z. B. durch Gießen oder durch Zusammenfügen aus entsprechenden Kupferstäben und -ringen, für sich angefertigt. Der fertiggestellte Kurzschlußkäfig wird dann in die zur Herstellung des Läuferkörpers dienende Form eingelegt, in die das Pulver, beispielsweise ein Gemisch aus Eisen und Isolierstoff, eingefüllt und durch Rütteln, Pressen od. dgl. verdichtet wird. Dadurch wird .der Vorteil erzielt, daß die zur Herstellung des Läuferkörpers erforderliche Form besonders einfach gestaltet werden kann, da Kerneinsätze für die Nuten in Fortfall kommen. Man kann abweichend von dem vorgeschilderten Verfahren auch so vorgehen, daß nur die Wicklungsstäbe in :die Form eingesetzt werden und die Kurzschlußringe nachträglich nach Fertigstellung des Läuferkörpers an diese angesetzt werden.According to the invention, the sintering process in the manufacture of Iron bodies of electrical machines are advantageously used to to improve the manufacture of the rotor of electric squirrel cage motors and to simplify that the short-circuit cage previously produced for itself in any way is embedded in the rotor body during sintering. To this end, will So the short circuit cage initially, z. B. by casting or by joining corresponding copper rods and rings, made for yourself. The completed The squirrel cage is then made into the form used to manufacture the rotor body inserted into which the powder, for example a mixture of iron and insulating material, Filled and by shaking, pressing or the like. Is compacted. This makes .der The advantage achieved is that the shape required to manufacture the rotor body is particularly good can be designed simply because core inserts for the grooves are no longer required. One can deviate from proceed according to the procedure outlined above, that only the winding bars are inserted into: the shape and the short-circuit rings can be attached to this after completion of the rotor body.
