GENERATOR
SINGLE
PHASE
DESCRIPTION
The
BC
generator
is
a brushless, self-excited generator which
requires only
the
driving force of the engine
to
produce
an
AC
output. The stator houses two sets of windings;
the
main
stator windings and the exciter windings. When the generator
is
started, residual magnetism
in
the
four rotating poles
induces a current in the stator which then generates
an
even
larger current in the exciter windings. This mutual build
up
of current in the four rotating poles
and
in
the
exciter
wind-
ings
quickly reaches the saturation point of
the
capacitor(s)
and
a regulated energy
field
is
then maintained in the
stator.
At
the
same time,
this
regulated
field
produces a steady
voltage
in
the
stator windings which can then be drawn off
the
generator's
AC
terminals
to
operate
AC
equipment. The
generator
is
a single-phase, reconnectable
120
volt
AC
two-
wire
or
120/240
voltAC three-wire,
at
60
hertz; or
110
volt
AC
two-wire or
230
volt
AC
two-wire,
at
50
hertz. Refer
to
the
SPECIFICATIONS section of
this
manual
for generator
ratings. The generator's data plate
gives
the
voltage, current
and
frequency rating of
the
generator.
An
AC
wiring decal
is
affixed
to
the
inside of the louvered cover
at
the generator
end.
A diagram of
the
various
AC
voltage connections
is
provided
on
the
decal.
An
Integral Controller (IC) is mounted
inside
the
generator and supplies a continuous
DC
charge
to
the generators starting battery when
the
generator
is
running.
For more information see
the
INTEGRAL CONTROLLER
DC
CHARGER section
in
this manual.
Circuit
Breaker
A circuit breaker is installed on all single phase
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
corning into
the
generator.
NOTE:
This circuit breaker is available as a WESTERBEKE
add-on kit
for
earlier model generators; contact your
WESTERBEKE dealer.
