Description
Es ist in vielen Fällen erwünscht, die Käfigwicklungen ,aus Aluminium" von Asynchronmotoren gegenüber dem aus lameliierten Blechen zusammengesetzten Läuferkörper zu isolieren. Durch die Herstellung der Isolierung wird indessen die Fabrikation der an sich außerordentlich einfachen Motoren erheblich komplizierter; insbesondere gilt dies dann, wenn die Käfigwicklungen gegossen werden.In many cases it is desirable to have the cage windings, made of aluminum, from asynchronous motors to insulate against the rotor body composed of laminated metal sheets. By making the insulation however, the manufacture of the engines, which are extremely simple in themselves, becomes considerable more complicated; this is especially true when the cage windings are cast.
Gemäß der Erfindung wird in außerordentlich vorteilhafter Weise eine Isolierung der eingegossenen Käfigwicklung dadurch erzielt, daß vor dem Eingießen des Wicklungsmetalls die Nuten des Läufers mit einem Anstrich oder Überzug aus einer oxydierend wirkenden Paste versehen werden, der beim Eingießen der Käfigwicklung auf den. in den Nuten liegenden Leiterstäben eine Oxydschicht hervorruft. Wird vor dem Eingießen des AIuminiums in die Nuten ein Überzug eingebracht, welcher ein Metalloxyd oder Superoxyd enthält, so bildet sich unmittelbar beim Eingießen des Aluminiums auf der Außenseite der Leiterstäbe eine Aluminiumoxydschicht, welche eine außerordentlich gute Isolierung der Leiterstäbe gegenüber dem Blechpaket herbeiführt. Beispielsweise können Metalloxyde oder Superoxyde verwendet werden, die in der Akiminothermie eine Rolle spielen.According to the invention is an extremely advantageous isolation of the cast-in cage winding achieved that before pouring the winding metal the grooves of the runner with a paint or coating of an oxidizing agent Paste are provided, which when pouring the cage winding on the. in the grooves lying conductor bars creates an oxide layer. Used before pouring the aluminum If a coating is introduced into the grooves which contains a metal oxide or superoxide, it is formed immediately at Pouring the aluminum on the outside of the conductor bars an aluminum oxide layer, which an extremely good insulation of the conductor bars against the laminated core brings about. For example, metal oxides or super oxides can be used play a role in akiminothermia.
Besonders vorteilhaft ist die Verwendung von Superoxyden, beispielsweise Braunstein (MNO2). An Stelle von Metalloxyden können aber auch andere Verbindungen gewählt werden, welche oxydierend auf die eingegossenen Leiterstäbe auf der Oberfläche einwirken.The use of superoxides, for example manganese dioxide (MNO 2 ), is particularly advantageous. Instead of metal oxides, however, other compounds can also be selected which have an oxidizing effect on the conductor bars cast on the surface.
Selbstverständlich kann die Erfindung auch dann Anwendung finden, wenn die Käfigwicklung durch Spritzguß hergestellt wird. Auch bei Doppelkäfigmotoren kann von der Erfindung Gebrauch gemacht werden,Of course, the invention can also be used when the cage winding is made by injection molding. Even with double cage motors, the invention Be made use of
