ABSTRACT:
An epoxy powder is electrostatically charged and spray-coated onto the series loop connections 16, 18 of a dynamoelectric machine. With the series loop connections grounded, the electrostatically charged particles adhere to the connections and wrap about the front, back and sides of the connections to provide a substantially uniform thickness or build-up of the electrically insulating epoxy powder. With the series loop connections preheated, the epoxy will begin to melt and flow, further ensuring a uniform build-up and thickness about the connections. The spray-coating is then heat-cured, thereby affording electrically insulated series loop connections at the opposite ends of the dynamoelectric machine.
