DC alternator Citroen DS, from approx year of construction 1961. New part! 50A, 12 volt, for 2

V-belts. Distance between the mountings: 105 mm. But, it is actually a modern AC alternator with integrated alternator regulator, in the classic DC housing. The advantages are: Much more stable power output even at low speeds, much lighter, very durable. The alternator regulator must be bypassed for connection (wiring diagram enclosed). Replaces original alternator: Paris Rhone G10C48 / Ducellier 5320 / 7336

Citroën DS Alternator: How It Works and Its Importance

An alternator is an electrical generator, usually designed as a three-phase generator and driven by the internal combustion engine. It supplies power to the vehicle’s electrical systems and the starter battery.

Why is it called an alternator?

The name “alternator” comes from the fact that the generator originally supplied power only to the vehicle’s lighting system. The magneto ignition system, which was common at the time, was independent of this, as it operated without an external power supply.

In the past, the engine was started with a crank, so there were no starters that required electricity.

Incidentally, nearly all French vehicles built up until the 1970s can still be started with a hand crank!

The Citroën 2CV could even be started this way until the 1990 model year. But the Citroën DS could also be started with a crank throughout its entire production run. The same applies to the Renault R4 and the Peugeot 203, 403, and 404.

There are a few other names for the power generator, such as alternator, generator, or dynamo. In Switzerland and in Slavic-speaking regions, the power generator is called a dynamo. In automotive engineering, it is correctly referred to as a generator. In common usage, however, the term “light machine” has become established.

Please note that the generator’s energy is required by both the engine and numerous safety and comfort systems. Furthermore, it is essential that the generator has sufficient power capacity to ensure reliable battery charging.

Typically, the generator is driven by the engine via a V-belt.

Operating Principle of the Alternator

The operating principle of an alternator is based on electromagnetic induction.

This means: When an electrical conductor moves through a magnetic field, an electrical voltage is generated in the conductor. It does not matter whether the magnetic field or the conductor is moving.

Main components of the alternator

The main components of the generator are:

  • Stator winding
  • Rotor
  • Regulator
  • Rectifier

The rotor generates the magnetic field. The strength of the magnetic field depends on the current flowing through the rotor. Regulation is performed by the regulator. As soon as the rotor begins to rotate, an alternating voltage is generated in the stator windings. This is converted into a direct voltage by the diodes of the rectifier before it enters the vehicle electrical system.

In current practice, the use of a three-phase generator, also known as an AC alternator, has become standard.

However, DC generators were still very commonly installed until the mid-1970s. Since DC alternators had to be built very robustly (and were therefore very heavy) and their current output depended heavily on engine speed, the switch was made to three-phase alternators. Their advantages include a compact design, low weight, and high current output even at low speeds.

We also offer three-phase alternators that look just like the old DC generators. Yet they often weigh only one-third as much as the original DC generators!

Generators today are maintenance-free units. To ensure they can perform their function throughout the vehicle’s entire service life, the condition and tension of the drive belt (V-belt) must be checked regularly. This is done as part of the maintenance intervals prescribed by the vehicle manufacturer. If the drive belt is cracked and worn, it must be replaced immediately.

However, if your classic car still has an original alternator (DC generator) from the 1960s, 1950s, or even earlier, its bearings must also be oiled regularly.
