Abstract
A motor housing and brush holder device is constructed, as by molding, in such a manner as not to require any machining operations subsequent to its being molded and assembled, and it can be molded of either conductive or nonconductive materials. The housing, in this case, is of nonconductive high impact strength material and is a single preformed molded piece. The housing includes an integrally molded generally cylindrical stepped bearing recess or pocket for the end of an armature shaft and brush holders spaced axially and radially of the bearing recess. The shape of the bearing and its keeper is unique as well as the brushes and associated structures and the manner in which they supply power to the windings of the stator field coils.
