ABSTRACT:
A motor (10) for a vehicle includes a stator assembly (14) and a rotor assembly (16). Bearing structure (20, 22) support the rotor assembly to permit rotation of the rotor assembly with respect to the stator assembly. A shaft (30) is threadedly engaged with the rotor assembly and is constructed and arranged such that rotation of the rotor assembly causes linear movement of the shaft. A perfluoropolyether (PFPE) based lubricant (38), having an thermal functionality upper temperature limit of over +200° C., lubricates at least the bearing structure.
