The functions of the alternator
|
The alternator plays a major role in the charging system. The alternator has three functions of generating electricity, rectifying current and regulating voltage. .
| (1) |
Generation
|
| The rotor (electromagnet) is driven via the pulley and V-ribbed belt from the engine causing it to generate alternating current in the stator coil. |
| (2) |
Rectification
|
| Since the electricity generated in the stator coil is alternating current, this cannot be used for the DC electric devices installed on the vehicle. To use the alternating current, the rectifier is used to rectify the alternating current into direct current. |
| (3) |
Regulation of voltage
|
| The IC regulator regulates the generated voltage to a constant value, even when the alternator speed or the amount of current required for the vehicles electric system varies. |
