ABSTRACT:
An armature of the prior art has a lamination packet which leads to a high loss of magnetic flux in the lamination, since it completely encloses the magnets that are disposed in the lamination.An armature (1) of the invention comprises at least one lamination (1) that only partly encloses the magnets (24). Losses in the magnetic flux are thus reduced.
