APPLICATION
& ENGINEERING DATA
GENERATOR FEATURES
Four pole, revolving field generator, directly connected to the
engine shaft through a heavy-duty, flexible disc for permanent
alignment.
Generator meets temperature rise standards for Class "F"
insulation as defined by NEMA MG1-22 and NEMA MG1-1.
Stator windings are "trickle" varnished and rotor windings are "roll-
dipped" for complete Class H impregnation.
All model designs pass a three-phase symmetrical short circuit
test to assure system protection and reliability.
Unit tested for motor-starting ability by measuring instantaneous
voltage dip with a waveform data acquisition system.
All models utilize an advanced wire harness design for reliable
interconnection within the circuitry.
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.
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.
Alternator is of drip-proof guarded construction.
Fully life-tested protective systems, including "field circuit and
thermal overload protection" and standard main-line circuit
breakers capable of handling full output capacity.
System torsional acceptability confirmed during Prototype Testing.
