GA-3.6RZ2 — GENERAL INFORMATION
GA-3.6RZ2 FAMILIARIZATION
Generator
The Multiquip Model GA-3.6RZ2 generator has been designed
as a portable lightweight power source for 60 Hz (single-
phase) vibrators, lighting facilities, power tools, sermersible
pumps and other industrial and construction machinery.
This generator employs the highly reliable ROBIN engine.
The alternator, a brushless revolving-field type, single phase
is permanently aligned to the engine through rigid coupling.
The entire generator is mounted on rubber vibration isolators
that have a steel base backplate which is attached to the
protective steel pipe carrying frame. The protective carrying
frame is made of steel tubing and fully wraps around the
generator to protect against damage.
This portable generator is supplied with a electrical
control
box
. To reduce vibration caused by the engine, the control
box is also placed on rubber isolators.
Control Box
The control box has the following: ( outputs are 60 Hz, single
phase)
l
One 120V output receptacle.
l
One 240V output receptacle.
l
One 120V output receptacle (GFCI protected).
l
One main 13.5 amp circuit breaker.
l
AC Voltmeter
l
Idle Control Switch
l
Full Power Switch
l
Ground Terminal
Excitation System
All GA-series generators use a magnet attached to a flywheel
to produce AC voltage from a lamp coil beneath the flywheel.
As the magnetic passes the coil it produces approximately
19-22 AC volts.
This voltage (19-22 VAC) is then sent to the control box that
contains three rectifying diodes:
l
Excitation (diode 1)
l
Battery (diode 2)
l
Slow Down (diode 3)
The AC voltage will pass through the excitation diode that
converts the voltage to DC power.
This DC power is then sent to the excitation windings housed
within the main windings commonly called the "stator".
This voltage is then transferred into the rotor through
induction. The rotor contains two diodes within it which rectify
the DC voltage and send it out through the main windings,
as AC voltage.
Engine
The four-cycle air-cooled ROBIN gasoline engine is designed
to meet every performance requirement of this generator.
