Understanding Alternators

Rotor The rotor consists of a coil of wire wrapped around an iron core. When current travels through the wire coil - called "field" current - a magnetic field is produced around the core. The strength of the field current determines the strength of the magnetic field. This current comes in D/C form, aka direct current. The current is supplied to the wire coil by a set of brushes and slip rings. The rotor is driven by the alternator pulley, rotating as the engine runs. Stator Surrounding the rotor is another set of 3 coils called the stator. The stator is fixed to the shell of the alternator and does not turn. As the rotor turns within the stator windings, the magnetic field of the rotor sweeps through the stator windings, creating an electrical current in the windings. An alternating current is produced because of the rotation of the rotor. The three stator windings are spaced inside the alternator 120 degrees apart, producing three separate phases of output voltages.
