Abstract
A method for producing a stator for an electric machine includes providing a stator with an annular stator body, from which a plurality of stator teeth protrude radially inwardly, wherein an intermediate space is formed in each case between two stator teeth that are adjacent in a circumferential direction, encapsulating two stator teeth adjacent in the circumferential direction with a first plastic mass, arranging a stator winding on a stator tooth, fixing the stator winding on the stator tooth by encapsulating said stator winding with a second plastic mass, following the encapsulation with the first plastic mass and before the fixing of the stator winding, a first mask is introduced into the intermediate space between the two stator teeth, such that the volume of the intermediate space that is filled with the first mask remains free from the second plastic mass to form a cooling duct during the encapsulation.
