Abstract
Description
Die Erfindung betrifft einen Magnetpol für einen Permanentmagnet-Gleichstrommotor, insbesondere eine magnetisch leitende Konstruktion, die von Selten-Erden-Steifenmagneten und Polschuhen des Stators gebildet ist. Außerdem weist ein Eisenkern des Rotors eine Mehrzahl von vorspringenden Abschnitten auf, die in spiralförmig abgeschrägter Weise ausgebildet sind, damit ein Hängenbleiben des Rotors verhindert wird, wenn Welligkeit der Flussverteilung an Verbindungsstellen zwischen Streifenmagneten vorkommt.The Invention relates to a magnetic pole for a permanent magnet DC motor, in particular a magnetically conductive construction, that of rare-earth magnet and pole shoes of the stator is formed. In addition, an iron core of the Rotor has a plurality of projecting portions in spirally Bevel Way are formed so that snagging of the rotor prevented when waviness of the flow distribution at joints occurs between strip magnets.
