Description

Trapezförmige Aussparungen sind fertigungstechnisch leicht herzustellen, und durch die in Richtung des Statorblechpakets verjüngende Form stellt sich eine Selbstjustage der Pole ein. Es stellt sich ein magnetischer Leitwert ein, der mit einer einstückigen Kombination von Pol und Statorblechpaket vergleichbar ist. Durch Sperrstifte wird eine gute reibschlüssige Verbindung zwischen Statorblechpaket und Pol hergestellt. Außerdem wird vorallem auf der dem gegenüber den Sperrstift liegenden Schenkel der trapezförmigen Aussparungen ein ausgezeichneter magnetischer Leitwert erreicht. Es können sowohl geblechte, als auch massive Pole aus elektrisch isolierendem und magnetisch gut leitendem Material eingesetzt werden, wie z.B. Eisencompositwerkstoff. In Verbindung mit vorgefertigten Zahnspulen, die durch die Pole in ihrer Lage fixiert sind wird die Herstellung wesentlich vereinfacht.Trapezoidal recesses are easy to manufacture, and the shape tapering towards the stator laminated core allows the poles to adjust themselves. The result is a magnetic conductivity that is comparable to a one-piece combination of pole and stator laminated core. Locking pins create a good frictional connection between the stator laminated core and the pole. In addition, an excellent magnetic conductivity is achieved, particularly on the side of the trapezoidal recesses opposite the locking pin. Both laminated and solid poles made of electrically insulating and magnetically highly conductive material can be used, such as iron composite material. In conjunction with prefabricated tooth coils that are fixed in position by the poles, production is made much easier.
