摘要:
A stator of an electrical machine has a cross section, a longitudinal extension, a jacket surface, a plurality of winding holders configured for receiving field windings, the winding holders being distributed inhomogenously around an inner circumference of the cross section, such that a density of the field windings in at least one first region formed around a stator circumference is smaller than in an adjacent second region.
