Abstract
Machine components such as windings of motor stators and the like are treated by totally impregnating and encapsulating the windings through the use of an apparatus on which the motor stator or the like may be selectively mounted on a platform in one of two positions 180.degree. apart and then inclined downwardly from the horizontal with the motor stator then being rotated and the encapsulating fluid poured therein during rotation thereof. Rotation is continued until the thermosetting epoxy hardens, thus eliminating the tendency of the fluid material to drip off because of gravity.
