ABSTRACT:
A rotor for an alternating current generator of a type that has two pole segments provided with interleaved pole teeth and a core disposed between the segments that carries a field coil. The shaft of the rotor carries a slip ring assembly having two metallic slip rings. A ball bearing is disposed between one of the pole segments and the slip ring assembly. A portion of the shaft that is located inside of the inner race of the ball bearing has a pair of slots and wires for connecting the field coil to the slip rings are located in the slots and inside the inner race of the bearing. The electrical connections between the ends of the field coil and the slip rings includes wires that are twisted together to form twisted wire portions. The twisted wire portions are locked or fixed to a fan that is formed of thermoplastic material by material of the fan that completely encircles portions of the twisted wire portions.
