Description

Während bei normalen elektrischen Maschinen mit axialem Luftspalt die Blechpakete aus einzelnen Blechscheiben bestehen, haben der Ständer und Läufer -bei Scheibenmaschinen, bei denen der Luftspalt in einer zur Achse senkrecht stehenden Ebene liegt, ein aus je einem Band gerolltes Blechpaket mit radial verlaufenden Nuten. Das umlaufende Blechpaket muß daher in besonderer Weise gegen Fliehkraftwirkung geschützt sein, und zwar um so mehr, als der Außendurchmesser des umlaufenden Teils bei Scheibenmaschinen größer ist als bei entsprechenden Maschinen mit axialem Luftspalt. Dies kann erfindungsgemäß dadurch erreicht werden, daß man die bei normalen Maschinen mit axialem Luftspalt aus Gründen einer einfachen Fertigung verwendete Ausführung des Käfigläufers, bei ,der der Käfig zusammen mit dem Läufer aus einem Stück gegossen, insbesondere gespritzt ist, auf Scheibenmotoren überträgt. Man erhält dadurch eine sehr stabile und dabei einfache und billige Läuferbauform. Die Erfindung wird <in Hand der "Zeichnung näher erläutert: Mit i ist der feststehende Ständer eines Scheibenmotors mit einer Wicklung z bezeichnet. Der Läufer 3 des Motors hat eine Käfigwicklung 4, die zusammen mit dem Läuferträger, Nabe 5 und gegebenenfalls den Lüfterflügeln 6 aus einem Stück gespritzt ist. Der Läuferträger kann, wie bei 7 gestrichelt angedeutet, Ausschnitte haben, um Kühlluft durch das Ständeritinere anzusaugen.While in normal electrical machines with an axial air gap The laminated cores consist of individual sheet metal disks, the stator and rotor have -in disc machines where the air gap is perpendicular to the axis Level lies, a rolled sheet metal package each from a band with radially extending Grooves. The rotating laminated core must therefore counteract centrifugal force in a special way be protected, more so than the outer diameter of the rotating part for disk machines is larger than for corresponding machines with an axial air gap. This can be achieved according to the invention by the fact that in normal machines with an axial air gap used for reasons of simple production of the cage rotor, in which the cage is cast from one piece together with the rotor, in particular is sprayed, transfers to disc motors. This gives you a very stable and at the same time simple and cheap rotor design. The invention is <in Hand of the "drawing explained in more detail: With i is the stationary stator of a disk motor denoted by a winding z. The rotor 3 of the motor has a cage winding 4, which together with the rotor carrier, hub 5 and possibly the fan blades 6 is molded in one piece. The rotor carrier can, as indicated by dashed lines at 7, Have cutouts to draw in cooling air through the inside of the stand.
