GENERATOR CONSTRUCTION [L8, LF, L3]
id0117b11023a9
• With the elimination of the voltage regulator, generator control is carried out by the PCM. Excitation current in the field coil is increased or decreased by the duty signal from the PCM sent to the power transistor built into the generator.
• Two delta connection type stator coils have been adopted. Due to this, the generator operation noise (electrical noise) is reduced and pulsation occurring through voltage rectifying in the stator coil is minimized, as a result, stable voltage output is supplied.
• A generator duct made of plastic, and a generator heat insulator made of iron have been adopted to protect the generator from the exhaust manifold heat.
