The permanent magnets on the magnet carrier (1) induce an
alternating current proportional to speed in the coils
of the stator (3).
NOTE!
The connector at cable (2) on the alternator can be
one of various versions.
4.2.2 Alternator
regulator (option)
Fig. 8: Example: Alternator regulator
The alternating current is rectified in the alternator regulator (fig. 8)
and constantly regulated to approx. 14.2-14.5 V.
