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 MG1-22.4 and NEMA MG 1-1.65, while the insulation system meets the requirements
for the higher class “H” rating.
-
Unit
tested for motor starting ability by measuring instantaneous voltage dip with
a wave form 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 self-ventiliated and 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.
