Consisting on four parts - an armature, rotor blank, bearing and pinion gear. The assembly operates in a motor drive for automatic sliding minivan doors and opening and closing tailgates. Made from a P/M phosphorous iron material, the parts have a density of 7.0 g/cm3, an ultimate tensile strength of 45,000 psi and a yield strength of 32,000 psi. The parts are made to a net shape, except for the rotor whitch requires a turning operation on the hub. Innovative tooling provides the required density in the parts to satidfy magnetic and strength properties of the rotor.
