Abstract
A method of servicing an electro-dynamic apparatus (10) such as a traction motor of a locomotive wherein a degraded surface (52) of electrical insulation (50) in the interior of the apparatus is spray coated with a layer of a sealing material (56). The service is provide without the necessity for removing or disassembling the apparatus by inserting a nozzle (64) of a spraying device (60) through an access opening (42) in the frame head (20) of the apparatus. The sealing material is delivered to the nozzle through a flexible delivery tube (66) having an inner tube (80) defining a passageway (82) for the sealing material and a concentric outer tube (84) defining an annular passageway (86) for compressed air for propelling the sealing material from the nozzle.
