Generator — general description (Peugeot 305)

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

The main advantage of an alternator is that it is capable of delivering a high charge at low engine speeds. When using a DC generator in city driving conditions, the battery is practically not charged, while an AC generator, under the same conditions, charges the battery even with the windshield wipers, headlights, heater, etc. 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 from the engine via a pulley mounted on a key on the rotor shaft. A fan located next to the pulley cools the generator by forcing air through it. This fan is an integral part of the generator. It is specially designed to operate efficiently with minimal noise. Direction of rotation: clockwise (when viewed from the drive side). The voltage regulator is factory adjusted and does not require maintenance. If the regulator malfunctions, it must be replaced as an assembly.
