Abstract
A stator module for an electric motor has a stator laminated core with a number of inwardly directed stator teeth and a rotating-field winding with a plurality of phases arranged on the stator teeth. The rotating-field winding has at least one coil per phase, which coil is electrically connected to a first phase end and a second phase end. A laying ring is placed onto the stator laminated core at the end face and surrounds the stator teeth as coil body in order to guide the rotating-field winding. An annular cover is placed onto the laying ring at the end face, on which cover each of the phase ends is contacted with one of the phase ends of another phase, in such a way that the entire rotating-field winding does not protrude radially externally beyond an outer periphery of the stator laminated core.
