Abstract

Spatially mutually close pole components are offset with respect to one another such that their influences on a given harmonic of the vibrations occurring during operation cancel one another as much as possible. The present invention therefore suggests concepts and makes dimensioning proposals by means of which certain harmonic orders of the operating noise can be reduced.
