ABSTRACT:
A method and apparatus for coating insulating materials onto the outer surface of an armature of an electric motor whereby insulating material is inhibited from being coated on a commutator and a driving shaft associated with the armature by covering the commutator and a portion of the driving shaft with a cap and directing an air flow through a gap formed between the cap and the commutator and the driving shaft such that air is discharged near a boundary between a commutator base and the armature, thus preventing insulating material from entering the gap and coating the commutator or the portion of the driving shaft.
