(2) Regulator (Contact type)
The alternator generates 3-phase current at a
fixed
coil by the rotation of a rotor which is then
emitted as full-wave rectified current by a diode. The
alternator can generate power at all speeds from
low
to high.
(D1403-B, D1703-B, V1903-B, F2803-B)
A compact alternator with an IC regulator is used,
having the following characteristics:
0 Approximately 26% lighter and 17% smaller than
a standard alternator.
0 Cooling performance and safety have been
improved by combining the cooling fan
with the
rotor and incorporating the fan
/ rotor unit inside
the alternator.
0 IC regulator is fitted inside the alternator.
0 The rectifier, IC regulator and similar components
are easy
to remove, making it easier to service the
alternator.

The regulator regulates the charging voltage.
Since the alternator speed
is varied by engine speed
variation, the output voltage from alternator varies.
However, constant voltage
(12 V) must be supplied to
the battery. That is the regulator which works to
keep the charging voltage at
12 V.
