Abstract
An electric motor assembly includes an electric barrier member positioned between the electric brushes and the bearing. The electric barrier member preferably is a generally annular disk made from a high-temperature dielectric material. The non-conductive barrier member ensures that no electrical communication occurs between the brushes and the bearing despite a close proximity between those components. A method of making a motor assembly to include a non-conductive barrier member designed according to this invention is also disclosed.
