SYSTEM OVERVIEW
Harrison Hydra-Gen hydraulic generators are
comprised of several components. A general
hydraulic and electrical component overview for our
generator is described below.
• Hydraulic Pump: The hydraulic pump sends
hydraulic fluid (oil) to the motor at a constant
flow under varying engine speeds.
• Motor: The hydraulic motor drives the
alternator.
• Alternator: An AC brushless revolving field
alternator provides regulated 120/240 VAC.
• Heat Exchanger: When the oil leaves the motor
it is cooled in an oil-to-air heat exchanger before
it is returned to the reservoir.
• Hydraulic Reservoir: The hydraulic oil
reservoir is equipped with an oil filter, oil level
sight glass, oil temperature gauge, oil filter and
breather cap.
• Display: The generator is also equipped with a
FRC meter which displays output voltage,
frequency, current, oil temperature, and unit
running time.
