Generator — general description (Peugeot 305)

The generator produces an alternating electric current, which is converted by diodes into a direct current. This current is used to charge the battery.

The main advantage of an alternator is that it is able to provide a high charge at low engine speeds. When using a DC alternator in city driving conditions, the battery is practically not charged, while an alternator in the same conditions charges the battery even when the wiper, headlights, heater, etc. are on.

The generator is a ventilated generator with a rotating magnetic field and consists mainly of a lamellar stator, on which the output winding is wound, and a rotor carrying the excitation winding. Both ends of the rotor shaft rotate in sealed, lubrication-free ball bearings.

The rotor is belt driven by the engine through a pulley mounted on a key on the rotor shaft. A fan next to the pulley cools the alternator by forcing air through it. This fan is an integral part of the generator. It is specially designed for efficient operation with minimal noise. Direction of rotation - clockwise (when viewed from the drive side). The voltage regulator is factory adjusted and requires no maintenance. If the regulator fails, it must be replaced as an assembly.
