Abstract
The insertion of electrically insulating paper from a continuous roll into slots of a stator created by outwardly projecting teeth is described herein. The insertion of the insulating paper is done by the insertion of prewound coils in the stator slots. The electrically insulating paper is not cut prior to its insertion in the slots, thereby completely covering the outer surface of the stator. The insertion systems and methods described herein are also optionally concerned with the insertion of interphase insulation paper between the different coils inserted in the stator slots and with the insertion of slot closing wedges.
