Abstract

An electric motor housing assembly (10) for electromechanical drives in automobiles is injection molded from a resin material. An armature bearing (18), mounting holes (30), and a flux ring (38) are molded in place within a housing (12) so that inner cylindrical surfaces (20 and 40) of the armature bearing and flux ring are centered with respect to the mounting holes (30) along a central axis (34). Protrusions (52 and 52) are molded through openings in the flux ring (38) for holding permanent magnets (44 and 46) in place against the flux ring.
