GENERATOR
DESCRIPTION
This generator is a 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 creates an electromagnetic field which rotates
through the windings
of
the main stator, inducing
AC
voltage
which is supplied to a load. A transformer is connected
in
parallel to the
AC
output
of
the main stator. An
AC
voltage is
produced
in
the auxiliary windings
of
the transformer and
main stator and is,
in
tum, supplied to a full-wave bridge rec-
tifier. The rectifier produces a
DC
voltage to further excite
the exciter stator windings, enabling the generator to produce
a rated
AC
output as the generator speed reaches its set hertz
rpm.
An optional solid-state voltage regulator is available to work
in
tandem with the transformer regulator to produce a more
stable
AC
output.
A circuit breaker is installed on all current 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 genera-
tor to insure that no
power is coming into the generator.
NOTE:
This circuit breaker is available as a WESTERBEKE
add-on kit for earlier model generators; contact your
WESTERBEKE DEALER.
