Abstract

A method for inserting a winding (56) consisting of a plurality of phases (32, 35, 38) by drawing said winding into a round stator iron (47) having grooves (50) and teeth (53), wherein the phases (32, 35, 38) are previously formed into a star shape and the phases (32, 35, 38) are formed into a star shape in such a manner that winding sides are part of the star shape, and in a following step, an accommodating crown (20) is provided, in which a number of slots (29) for accommodating the winding sides have been provided, said method being characterized in that the individual n phases (32, 35, 38) are each designed in partial phases (70, 73, 90, 93, 100, 103), a partial phase (70, 73, 90, 93, 100, 103) of a phase (32, 35, 38) being arranged in a first set of the z grooves (50), n teeth being arranged between two proximately spaced grooves (50) in which winding sides of a partial phase (70, 73, 90, 93, 100, 103) are arranged, and the further partial phase (70, 73, 90, 93, 100, 103) being arranged in a second set of the z grooves, n teeth likewise being arranged between two proximately spaced grooves in which winding sides of the further partial phase (70, 73, 90, 93, 100, 103) are arranged and a spacing being provided between the two sets in such a manner that a tooth (53) is arranged between the sets.
