THE
SBEG
GENERATOR
SINGLE
AND
THREE
PHASE
DESCRIPTION
This
generator
is
a four-pole, brushless, self-excited generator
which requires only the driving force of
the
engine
to
produce
AC
output. The copper
and
laminated iron in the exciter stator
are
responsible for the self-exciting feature of
this
generator.
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 voltage
to
D<;
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
turn, supplied
to
a voltage regulator.
The
regulator produces a
DC
voltage
to
further excite the
exciter stator windings, enabling
the
generator
to
produce a
rated
AC
output. The voltage regulator senses
AC
voltage out-
put and adjusts
DC
excitation
to
the exciter stator winding
according
to
amperage load the generator
is
furnishing
to
maintain a constant voltage output.
DISC
PLATE'
CIRCUIT
BREAKER
A circuit breaker
is
installed
on
all WESTERBEKE
generators. This circuit breaker will automatically disconnect
generator power
in
case of
an
electrical overload. The circuit
breaker
can
be manually shut off
when
servicing the
generator
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
WESTERBEKE
dealer.
