Basic Principles of DC Generator Work

Before we discuss the workings of AC Generator / Alternator to help us briefly study DC generator to see the system charging in the right perspective. The DC generator shown in Fig. 1.5 consists of a series of armatures, where a soft iron core is fitted with many cable lines. This armature is placed in the housing where it contains an electromagnetic field.

At this point the generator looks the same as the starter motor. The armature starter motor, however, may rotate due to the interaction of the electro magnetic field. To induce voltage through electro magnetic, the armature must rotate by being driven by a pulley and a belt or through another mechanism by means of a gear. The end of the armature coil end is connected to the commutator. In the generator armature generated Ac is shown in Figure 1.6:

However, the result of the movement of the comutator and brush produces a tension between the corrugated bruh between 0 dn positive results, eliminating the negative portion of the sine wave. This wave is called DC wave and generated by DC generator. As shown in Figure 1.8. Spring pushes the brush to stick to the comutator as well as deliver current to the external voltage regulator as well as maintain current and voltage supply to the battery.
