Alternator field coil wire routing design

摘要

An alternator for a motor vehicle is disclosed. The alternator includes a stator having a stator winding, a rotor assembly positioned concentrically relative to the stator, and including at least one pole having an outer surface. The outer surface has a groove and includes a field coil disposed adjacent the at least one pole, the field coil having start and end leads. A slip ring is fixedly coupled to the start and end leads and a rotor shaft on which the field coil, the at least one pole and the slip ring are fixed. Moreover, the start and end leads are positioned within the groove and are retained in the groove by a locking feature formed in the outer surface of the at least one pole.
