Abstract
The invention relates to a stator module for an electric motor, especially an electric motor with transverse flux, comprising at least one stator unit that consists of at least one armature winding and which, when mounted, is associated with a rotor, whereby an interferric space is created in a radial direction in relation to the axis of symmetry of the electric motor. The invention is characterized by the following features: the stator unit comprises at least one return element that is made of a pressed material produced by means of powder metallurgy and which comprises a peripheral surface extending in a peripheral direction; two soft iron units which can be formed from tooth elements are associated with the return element, whereby substantially U-shaped cross-sectional surfaces, when seen from an axial viewpoint, are formed and the tooth elements of the individual soft iron units form the limbs of the cross-sectional surfaces; the position of the armature winding is defined by the peripheral surface of the return element, oriented towards the rotor and the self-oriented front faces of the soft iron units.
