METHOD OF, AND APPARATUS FOR, MANUFACTURING LAMINATED DYNAMOELECTRIC MACHINE STRUCTURES

摘要

A method of, and apparatus for, making laminated motor structures for dynamoelectric machines is presented. Sheet stock (16) is advanced through a progressive die (38) for forming a lamina which is returned to the stock for advancement to an arbor (36), where a punch (32) is provided for removing the lamina from the stock and stacking it with previously formed laminae on the arbor. The arbor is then rotated a predetermined amount and lowered a predetermined distance in preparation for receiving the next lamina.
