ABSTRACT:
A portable oven for baking a motor or generator armature or other electrical winding mounted on a shaft for use in a process for cleaning and reinsulating the armature without removing the shaft from the operating environment. The oven is formed in the shape of a closed, hollow cylinder which encloses the armature and is supported by the armature shaft. The shaft is suspended horizontally on rotating hubs and moved longitudinally to project the armature out of the motor/generator casing. Support collars are attached to the shaft on either side of the armature. Wedge-shaped sections are attached to the collars to form circular ends of the cylindrical oven. Arcuate-shaped body members are attached between the ends to enclose a cylindrical surface. Each body member is furnished with heaters and perforated baffles for evenly heating the armature. An air inlet is formed in one of the wedge-shaped end sections and an air outlet is formed in one of the arcuate-shaped body members.
