The Sbeg Generator Single And Three Phase; Single And Three Phase - Westerbeke SBEG Series Operator's Manual

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 Dl;
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 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.

CIRCUIT BREAKER
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.
