BT- GENERATOR
This generalDr is a four-pole, brushless, self-excited generator
which requires only the driving force of the engine to pro-
duce AC output. The copper and laminated iron in the exciter
- -~ stator are responsilllefonl1e self-eJrcttln-g-fll"ature-ofthis-gen' -
erator. The magneti.c field produced causes an AC voltage to
be induced into the related exciter rotor windings during rota-
tion. Diodes located in the exciter rotor rectify this voltage to
DC 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. A step down 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 the
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. An optional solid-state voltage regulator is
available to work in tandem with the transformer regulator to
produce a more stable AC output.
