GENERATOR FEATURES

ˆFour pole, revolving field generator, directly connected to the engine shaft through a heavy-duty, flexible disc for permanent alignment.

ˆGenerator meets temperature rise standards for class “F” insulation as defined by NEMA MG1-22.4 and NEMA MG 1-1.65.

ˆStator windings are “trickle” varnished and rotor windings are “roll-dipped” for complete impregnation.

ˆUnit tested for motor starting ability by measuring instantaneous voltage dip with an oscillograph.

ˆAll models utilize an advanced wire harness design for reliable interconnection within the circuitry.

ˆMagnetic 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.

ˆVoltage 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.

ˆAlternator is of drip-proof guarded construction.

ˆFully life-tested protective systems, including “field circuit and thermal overload protection” and standard main line circuit breakers capable of handling full output capacity.

ˆSystem torsional acceptability confirmed during prototype testing.
