Abstract:
A dynamoelectric machine conductor bar, comprising: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; an electrically non-insulated gap between the strand insulation adjacent the conductors at the bar end portion; and an applied filler material filling the gap to electrically shield the conductor bar end portion, wherein the filler material defines a greater than 0.080 to about 1.5 inch continuous outer radius surface end portion, and wherein the filler material comprises an electrically non-conducting fillet and an outer surface of the fillet comprises a low conductivity paint having a conductivity in the range of 2,000 to 100,000 ohms per square in its cured state.
