Attention: When installing additional equipment, it is necessary to check whether the power of the existing generator will be sufficient and, if necessary, install a more powerful generator.
The generator is driven by the engine using a V-ribbed belt. In this case, the rotor with the excitation winding rotates inside the stationary stator windings with a speed exceeding the engine speed by about 2 times.
Through the carbon brushes and slip rings, the excitation current flows through the excitation winding. This creates a magnetic field. The position of the magnetic field relative to the stator winding is constantly changing depending on the speed of rotation of the rotor. Due to this, an alternating current appears in the stator winding.
Since the battery can only be charged with direct current, the alternating current is converted to direct current using a diode rectifier. The voltage regulator changes the charging current by switching the current in the excitation winding on and off, depending on the degree of charge of the battery. At the same time, the regulator keeps the operating voltage constant at 14 V, regardless of the speed.
