Description

Mit Dauermagneten bestückter stator für elektrische Maschinen Die Neuerung ist gerichtet auf einen mit Dauermagneten bestück- ten Stator für elektrische Maschinen und ist dadurch gekenn- zeichnet, daß radial gestellte rechteckige, plattenförmige Dauermagnete vorgesehen sind mit einer Magnetisierung in Richtung ihrer kürzesten Kanten. Zwischen diesen Magneten befinden sich Eisenkeile, die als Pole in den Statorinnenraum hinein- ragen. Stator equipped with permanent magnets for electrical machines The innovation is aimed at a stator for electrical machines and is therefore characterized draws that radially placed rectangular, plate-shaped permanent magnets are provided with a magnetization in the direction of their shortest edges. Located between these magnets iron wedges, which act as poles in the interior of the stator protrude.

In der Zeichnung sind zwei Ausführungsformen solcher Statorkörper im senkrechten Schnitt als Beispiele der Neuerung dargestellt.The drawing shows two embodiments of such stator bodies shown in vertical section as examples of the innovation.

Die Dauermagnete 1 sind in beiden Fällen von Eisenkörpern 2 gehalten. Die Magnetisierung ist so vorgenommen, daß je zwei Magnete 1 an den dazwischen angeordneten, im wesentlichen keilförmigen Eisenkörpern 2 mit gleicher Polarität anliegen.The permanent magnets 1 are held by iron bodies 2 in both cases. The magnetization is carried out in such a way that two magnets 1 each are attached to the essentially wedge-shaped iron bodies 2 rest with the same polarity.

Die Dauermagnete 1 überragen am Außenumfang um ein geringes die Eisenkörper 2. Diese besitzen ihrerseits Ansätze 3, die die Magnete1 überragen und sie teilweise nasenförmig umfassen. Die Ansätze 3 bilden die Pole des Stators.The permanent magnets 1 protrude slightly beyond the iron body on the outer circumference 2. These in turn have approaches 3 that protrude beyond the magnets 1 and they partially embrace nose-shaped. The approaches 3 form the poles of the stator.

Die keilförmigen Eisenkörper können als Formstücke durch Ziehen, Sintern oder Feingießen hergestellt werden. Auch die Körper 2 können auf diese Weise erzeugt werden. Es ist aber auch möglich, sie als lamellierte Eisenkern aufzubauen, wie dies an sich in der Elektrotechnik bekannt ist. Je nach den gegebenen Umständen können auch sogenannte Massenkerne an dieser Stelle benutzt werden.The wedge-shaped iron body can be used as molded pieces by drawing, sintering or investment casting. The bodies 2 can also be produced in this way will. But it is also possible it as a laminated iron core to build up, as is known per se in electrical engineering. Depending on the given Under certain circumstances, so-called mass cores can also be used at this point.

Die Statorkörper bekommen ihren Zusammenhalt dadurch, daß die Magnetkörper 1 und die Eisenkörper 2 zusammengeklebt werden. Gegebenenfalls können an den Enden nutenförmige Ausnehmungen vorgesehen werden zur Aufnahme der Flansche von Schrumpfringen aus nicht ferromagnetischem Werkstoff.The stator bodies get their cohesion from the fact that the magnetic body 1 and the iron body 2 are glued together. If necessary, at the ends Groove-shaped recesses are provided for receiving the flanges of shrink rings made of non-ferromagnetic material.
