Strip winding machine and method

摘要

A method and apparatus for winding axial air gap motor cores, using prepunched strip material, so that the finished cores have radially aligned slots. The invention includes a precise movement of the winding mandrel away from the punching means to gradually increase the interslot gap for each slot. The action of the punch press, mandrel rotation and linear mandrel motion are coordinated to prevent interference among these activities. The method of interslot gap sizing provides for proper radial slot alignment when the prepunched strip material is later wound on the mandrel.
