Manual Extract: Alternator – Static description
The main components of the charging system are the battery, the generator, and the battery discharge indicator light circuit. The generator is the self-rectifier type with a regulator built in.
Generator
The generator is the brushless type.
The main components include the rotor, stator, rectifier assembly, front bracket, rear bracket, IC regulator, bearing, and pulley.
The moving parts are the rotor and the pulley. The field coil is fixed to the rear bracket.
6 main diodes and 2 additional diodes are used to change the three-phase alternating current generated in the stator coil to a direct current.3 out of the 6 main diodes are referred to as positive diodes, and the rest are referred to as negative diodes. In addition, 3 small diodes that are referred to as the triodiode are used to supply the field current.
This generator has 3 terminals: the B terminal (direct current output terminal), the L terminal, and the R terminal.
Since the L terminal is connected to the field coil, it works as an input terminal for the initial excitation current together with the R terminal until the generator starts generating power.
Also, it functions as an output terminal. (Current capacity is 1 A.) When the L terminal voltage reaches the battery voltage, the charge light turns OFF. Since both bearings are sealed, periodic lubrication is not required. The IC regulator cannot be disassembled, so it should be handled as an assembly.
