ABSTRACT:
A method for coating a core of a small sized motor having a jig or the like by applying a liquid primer forming a primer coat film followed by applying a powder coating using either a friction charging type electrostatic powder gun or an inner charging type electrostatic powder gun. This method prevents rust from forming on the shaft hole and its peripheral portions covered by the jig, and it prevents the deterioration of the insulation coat film on the winding wires upon contact with burrs.
