GENERATOR FEATURES
■Four pole, revolving field generator, directly connected to the engine shaft through a
■Generator meets the temperature rise standards for class "F" insulation as defined by NEMA
■All prototype models have passed a
■All prototype models are tested for motor starting ability by measuring the 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 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 T.I.F. (Telephone Influence Factor) have been evaluated to acceptable standards in accordance with NEMA
■Alternator is
■Fully
■System Torsional acceptability confirmed during Prototype Testing.
