The assembly comprises a slotted stator core that supports a stator winding, a rotor bearing and a metallic heat dissipating insert that supports the bearing. The assembly has a plastic housing that is comprised of plastic material that is molded to the stator core and insert. The plastic housing does not encapsulate the stator winding. The metallic insert conducts heat away from the bearing and also adds stability to the plastic housing. | |
