Abstract

A permanent magnet for connecting with a connection device of an external rotor machine includes a north pole and a south pole as magnetic poles. A magnetic field runs from the south pole to the north pole, with a cross section of the permanent magnet having an envelope with a concave section. The envelope has, in the form of a sickle, the concave section and a convex section. The permanent magnet runs in an arcuate manner along the convex section, and the magnetic poles run in an arcuate manner along the concave section.
