ABSTRACT:
A process and an apparatus for providing a stator plate with windings where the stator plate has several stator slots distributed in a circumferential direction which are formed between poles and a stator core and end face disks formed of an electrically insulating material mounted on both faces, the end face disk having a winding wire receiver space lying radially and axially outside of the stator slots and running in the circumferential direction and arranged in such a manner that a directly adjacent stator slot is kept at least partially clear when the slot is skipped during winding of the winding pattern having a winding pitch of greater than 1 and the end face disk also having a radially projecting retaining finger between every two adjacent stator slots. The process for installing a winding wire under tension by means of a wire moving means in such a manner that the wire moving means is moved by means of a supporting arm in at least two controlled axes and, if necessary, conveyed through the stator core, the wire moving means rotated about an axis perpendicular to its longitudinal axis for installing the winding wire in the winding wire receiver space of an end face disk, the stator plate rotated forward to a next stator slot to be provided with windings with a corresponding switching pitch, and the winding wire led through an associated retaining finger of the end face disk.
