Abstract
The invention relates to a method for mounting a worm on an armature shaft of an armature for an electric motor. The invention proposes first mounting armature parts, such as an armature lamination packet with armature windings, a commutator, a bearing seat, and/or a bearing, on the armature shaft and then rolling the worm on the armature shaft. This has the advantage that the worm can have a greater diameter than does the armature shaft over its remaining length.
