ABSTRACT:
The invention relates to a primary component (2) for an electric motor (1), said primary component (2) being formed from at least one bundle of laminations (3) and comprises at least one flux guiding element (10) on one or both front faces (S1, S2) to reduce the ripple effect, said primary component (2) being separated from a secondary component (7) by a first air gap (δ1). The primary component (2) has at least one section (δ2) in the region of the flux guiding element (10), said section (δ2) being electrically non-conducting (Kel=0) and having a negligibly low magnetic permeability (μr≅1).
