CHAPTER 3

ALTERNATOR REPAIR

PRINCIPLES OF OPERATION

3-1

The rotor assembly (1) produces lines of force. It is electrically excited by battery current passing

through small brushes (2) riding on smooth slip rings. The stator assembly (3) contains the windings in

which AC voltage is produced. The stator assembly is stationary, so the windings are not subjected to

centrifugal force. The current is delivered at the connector assembly (4).
