ABSTRACT:
A method and apparatus for applying a solid particulate powder coating to a stator stack having a plurality of longitudinally extending stator slots. The apparatus includes a coating application station for applying powder particles to the stator stack, a coating removal station for displacing the powder particles from selected areas of the stator stack and a curing oven for curing the powder particles onto the stator stack. A collection hopper is provided for receiving recycled powder particles and includes a porous structural side wall for permitting air to exit the hopper while retaining the powder particles from passing into the environment around the system.
