摘要： A rotor shaft for electro-dynamic machinery such as a motor vehicle alternator includes a cold-headed slot through a bearing land formed on the shaft. The slot extends axially through a bearing land and either extends radially through a collar portion adjacent the bearing land, or communicates with a radially aligned shaped conductor on a slip ring. Preferably, two diametrically opposed slots are formed, and the slots provide a means for aligning the wires, for example, prior to encapsulation of the rotor by injection molding, while positioning the leads for engagement with the winding terminals and with the conductor rings on the slip ring bushing. Preferably, the shaft is made by a sequential set of cold heading steps which avoid deformation or uneven formation of the groove. A cold headed shaft formed without a collar is preferably through-fed in a single direction through one or more machining stations for production efficiency.

摘要： 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.

摘要： A molded rotor assembly (20) for a vehicle alternator and method for making the same are disclosed. The rotor assembly includes first and second pole pieces (24,26) aligned along a longitudinal axis (40), the pair of pole pieces (24,26) defining a region therebetween. A coil wire (46) is located in the region. The pole pieces (24,26) and a slip ring assembly (36) are mounted on a rotor shaft (38). The slip ring assembly (36) has a pair of slip rings (102,104) connected to a pair of terminals (96,98) which are attached to respective free ends of the coil wire (46) to form a pair of connections (126,128). A molded insert (22) is injection molded filling the region between the pole pieces (24,26) thereby encapsulating the connections (126,128) and the coil wire (96) and forming a smooth cylindrical periphery on the rotor assembly (20).
