Attention: When installing additional equipment, you should check whether the installed generator has sufficient power; it may be necessary to install a more powerful generator.
The generator rotates from the crankshaft via a V-belt. On diesel engines, the vacuum pump of the brake booster sits on the generator axis. The generator anchor with the excitation coil rotates inside the stator coil with double the engine speed. The excitation current flows through the excitation winding via carbon brushes and contact rings. This creates a magnetic field.
The position of the magnetic field relative to the stator winding constantly changes along with the rotation of the anchor. Thus, alternating current is induced in the stator winding. But since the battery can only be charged with direct current, the alternating current is converted to direct current by a rectifier on the diode board. The voltage regulator changes the magnitude of the charging current, turning the excitation current on and off depending on the state of charge of the battery. At the same time, the regulator maintains the voltage of the on-board network constant at about 14 V, regardless of the number of revolutions.
