Alternator components & their functions:

Regulator

The voltage regulator controls the amount of power distributed from the alternator to the battery in order to control the charging process. Regulators are designed with different functions and work depending on their specification.

Rectifier

The rectifier is used to convert current from alternating current (AC) to direct current (DC) during the charging process.

Rotor

The rotor is the spinning mass inside the alternator that rotates via the pulley and drive belt system. The rotor acts as a spinning electromagnet.

Slip Rings

The Slip rings are used as a means of providing direct current and power to the rotor.

Slip Ring End Bearing

The bearings are designed to support the rotation of the rotor shaft.

Stator

The stator consists of several coils of wire wound through an iron ring. The stator sits outside the rotor, when a magnetic field is created the electrical current is made.

Drive End Bearing

The bearings are designed to support the rotation of the rotor shaft.

Pulley

The pulley is connected to the rotor shaft and the drive belt system. Rotation created by the engine the drive belt system turns the pulley beginning the charging process.
