ABSTRACT:
A motor, particularly suited for carpet cleaners and other wet vacuuming appliances, includes a motor housing with a stepped bore. The stepped bore is part of a bearing/seal assembly that simultaneously clamps a bearing and compresses a seal member. The assembly maintains the motor's commutator at a substantially fixed axial location relative to the commutator's brushes, regardless of the extent to which the seal is compressed and regardless of any subsequent creep of the seal.
