Alternator field coil wire routing design

A rotor for an alternator, the rotor comprising:

• at least one pole having an outer surface, wherein the outer surface has a groove;
• a field coil disposed adjacent the at least one pole, the field coil having start and end leads;
• a slip ring fixedly coupled to the start and end leads;
• a rotor shaft on which the field coil, the at least one pole and the slip ring are fixed;
• and
• an insulating sleeve having a first and a second portion for covering the start and end leads, and
• wherein the start and end leads are positioned within the groove in the outer surface of the at least one pole.

An alternator for a motor vehicle, the alternator comprising:

• a stator having a stator winding;
• and
• a rotor assembly positioned concentrically relative to the stator, the rotor assembly including:
• an at least one pole having an outer surface, wherein the outer surface has a groove;
• a field coil disposed adjacent the at least one pole, the field coil having start and end leads disposed within the groove;
• a slip ring fixedly coupled to the start and end leads;
• a rotor shaft on which the field coil, the at least one pole and the slip ring assembly are fixed;
• an insulating sleeve covering the start and end leads;
• and
• a locking feature formed in the outer surface of the at least one pole for retaining the start and end leads.
