  • Apparatus and method for forming circular dynamoelectric machine field windings by pushing
    Patent number: 3985163
    Abstract: An apparatus and method for placing magnet wire in slots respectively defined by the blades of coil insertion apparatus which lie on an imaginary cylinder thereby to form a circular dynamoelectric machine field winding. The wire is pushed and simultaneously guided in a circular path which overlaps the cylindrical array of blades and which is aligned with the open ends of two of the slots whereby the wire is pushed into the two slots.
    Type: Grant
    Filed: June 25, 1975
    Date of Patent: October 12, 1976
    Assignee: Essex International, Inc.
    Inventors: Ralph A. Vogel, Patrick L. Grawcock
