Abstract

A method for producing a stator may include providing an annular stator body including a plurality of stator teeth arranged spaced apart from one another. The method may also include at least partially overmoulding at least two adjacent stator teeth with a first plastic mass. The method may further include arranging at least one stator winding on at least one stator tooth of the at least two stator teeth and fixing the at least one stator winding on the at least one stator tooth via at least partially overmoulding the at least one stator winding with a second plastic mass. The method may additionally include, prior to fixing the at least one stator winding, introducing a mask into an intermediate space defined between the at least two stator teeth to cover a surface portion of the stator body bounding the intermediate space radially outside.
