ABSTRACT:
The invention relates to an electronically commutated electric motor having a multi-pole magnetized permanent magnet, a plurality of flux guide units each of which features at least one flux collector section and one flux concentrator section, whereby each flux guide unit picks up a radial magnetic flux from the permanent magnet and redirects it into a transversal magnetic flux, and having a plurality of coils each of which is allocated to a flux guide unit and is arranged axially parallel to the permanent magnet.
