APPLICATION
& ENGINEERING DATA
GENERATOR FEATURES
n
Four pole, revolving field generator, directly connected to the
engine shaft through a heavy-duty, flexible disc for permanent
alignment.
n
Generator meets temperature rise standards for Class "F"
insulation as defined by NEMA MG1-22 and NEMA MG1-1.
n
Stator windings are "trickle" varnished and rotor windings are "roll-
dipped" for complete Class H impregnation.
n
All model designs pass a three-phase symmetrical short circuit
test to assure system protection and reliability.
n
Unit tested for motor-starting ability by measuring instantaneous
voltage dip with a waveform data acquisition system.
n
All models utilize an advanced wire harness design for reliable
interconnection within the circuitry.
n
Magnetic circuit, including amortisseur windings, tooth and skewed
stator design, provides a minimal level of waveform distortion and
an electromagnetic interference level which meets accepted
requirements for standard AM radio, TV, and marine radio
telephone applications.
n
Voltage waveform deviation, total harmonic content of the AC
waveform, and balanced T.I.F. (Telephone Influence Factor) have
been evaluated to acceptable standards in accordance with NEMA
MG1-22.
n
Alternator is of drip-proof guarded construction.
n
Fully life-tested protective systems, including "field circuit and
thermal overload protection" and standard main-line circuit
breakers capable of handling full output capacity.
n
System torsional acceptability confirmed during Prototype Testing.
