GENERATOR

The

generator is a brushless, self-excited generator which requires only the driving force

the engine

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 exciter windings. This flow

current then induces a greater current flow through the four rotat-

ing poles which then generates an even larger current

the exciter windings. This mutual build

cur-

rent in the four rotating poles and

the exciter windings quickly reaches the saturation point of the

capacitor(s) and a regulated energy field is then maintained

the stator. At the same time, this regulated

field

produces a steady voltage

the stator windings which can then be drawn off the generator's

ter-

minals

operate

equipment.
