THE
BE
GENERATOR
SINGLE
AND
THREE
PHASE
DESCRIPTION
This generator is a
four-IIDle,
brushless, self-exdted genera-
tor which requires only
the
driving
force
of the engine
to
'pro-
duce
AC output. The copper
and
laminated
iron
in
the exciter
stator are responsible
for
the
self-exciting feature of
this
gen-
erator.
The magnetic
field
produced causes
an
AC voltage
to
be induced into
the
related excitor rotor windings during
rotation. Diodes located
in
the
exciter rotor rectify this volt-
age
to
IX;
and
supply
it
to
the
windings of
the
rotating
field.
This creates
an
electromagnetic
field
which rotates through
the
windings of the
main
stator, inducing
an
AC voltage
which
is supplied
to
a load. An AC voltage
is
produced
in
the
auxiliary windings
of
the
main
stator
and
is,
in
tum, supplied
to
a voltage regulator. The regulator produces a DC voltage
to
further excite the exciter stator windings, enabling
the
gen-
erator to produce a
rated
AC output. The voltage regulator
senses AC voltage output
and
adjusts
DC
excitation
to
the
exciter stator winding according
to
amperage
load
the
gener-
ator is furnishing.
To
maintain
a constant voltage output.

CIRCUIT
BREAKER
A circuit breaker
is
installed on all WESTERBEKE genera-
tors. This circuit breaker will automatically disconnect gener-
ator power in case of
an
electrical overload. The circuit
breaker can be manually shut off
when
servicing the genera-
tor
to
ensure that
no
power
is
coming
into the boat.
NOTE:
This circuit breaker is available
as
a
WESTERBEKE
add-on
kit for earlier model generators; contact your
WEST-
ERBEKE
dealer.
