ABSTRACT:
A molded rotor assembly (20) including at least one molded fan (28), a method for making the same, and a vehicle alternator (160) using the molded rotor assembly (20) are disclosed. The rotor assembly (20) includes first and second pole pieces (24,26) aligned along a longitudinal axis (40) defining a region (122) between the pole pieces (24,26). Each pole piece (24,26) has an outboard axial face (69,71). At least one molded fan (28) is integrally molded to one of the axial outboard faces (69) of a pole piece (24). Preferably, a molded insert (22) is molded in the region (122) between the pole pieces (24,26) and is integral with the molded fan (28) to secure the molded fan (28) to the pole piece (24). Alternatively, anchoring recesses (241,245) are formed in an outboard face of a pole piece (224) with a molded fan (228) having anchoring portions (249,251) secured within the recesses (241,245) to retain the fan (228) to the outboard axial face.
