  • Method of making a dynamoelectric machine conductor bar and method of making a conductor bar dynamoelectric machine, the bar and the machine
    Patent number: 6768240
    Abstract: A method for making a dynamoelectric machine conductor bar, compromises providing a plurality of bundled together spiraling strand conductors having surrounding insulation to define a substantially rectangular shape with the strand conductors and strand insulation defining an opposing conductor bar end portion having an electrically insulated gap between the strand insulation adjacent the bar end portion; and applying a filler material to fill the gap to electrically shield the conductor bar end portion and to a greater than 0.080 to about 1.5 inch continuous outer radius surface end portion.
    Type: Grant
    Filed: May 30, 2003
    Date of Patent: July 27, 2004
    Assignee: General Electric Company
    Inventors: Karim Younsi, David A. Snopek, Luc Lafortune, Jeff D. Sheaffer, William R. Mischler, Mark Markovitz
