Abstract: A method for sheathing an armature for electric machines, in which a stack of lamellae that is equipped with grooves for armature windings is mounted on an armature shaft by means of a bore and is provided with at least one groove insulation with the aid of the sheathing process. The sheathing plastic flows through ducts that extend along the bore of the stack and the armature shaft. The plastic is molded in only on a first face of the stack and flows into the grooves and through the ducts. The plastic invades the grooves also from the second face after being discharged from the ducts and converges with the plastic discharged from the first face. The method implements fixing and insulation of the grooves while the groove insulation is provided with a minimum layer thickness for such sheathings at the bottom thereof in order to allow for maximum copper fillings.
