Attention: When installing additional equipment, you should check whether the power of the installed generator is sufficient, it may be necessary to install a more powerful generator.
The generator rotates from the crankshaft through a V-belt. On diesel engines, the brake booster vacuum pump sits on the generator axle. The generator armature with excitation coil rotates inside the stator coil at twice the engine speed. The excitation current flows through the excitation winding through the carbon brushes and slip rings. This creates a magnetic field.
The position of the magnetic field relative to the stator winding is constantly changing along with the rotation of the armature. This induces an alternating current in the stator winding. But since the battery can only be charged with DC, the AC is converted to DC by the rectifier on the diode board. The voltage regulator changes the amount of charge current, turning the excitation current on and off depending on the degree of battery charge. At the same time, the regulator maintains the on-board network voltage constant at about 14 V, regardless of the speed.
