Lightweight, Compact
The Robin engine and revolving field generator designs provide added output power per weight and economical operation.
Centralized Control
The switches, meters, and receptacles are located together on a large-sized control box, and all operating controls are
located on top of the engine for easy generator operation.
Large 16-Liter Gas Tank
* 16-liter (4.2-gallon) fuel tank is provided for ten hours of operation for Model RGX305 or seven hours for Model
RGX405. (at the 50Hz rated output power)
*RGX505 can operate for six hours (at the 5OHz rated output power) with a full tank.
*The tank has a fuel gauge which shows the remaining amount of fuel in the tank.
Solid State Ignition System
*Unlike the point system, the solid state ignition system has no contact points so that maintenance due to point wear
is unnecessary and constant output power can be maintained for long.
*Increased spark energy makes starting easy.
Extra-Quiet Operation
*All models are equipped with a large-sized, low-noise muffler.
*All models have a cyclone type air cleaner of a low-noise, dustproof type.
Small Voltage Fluctuations by AVR (Automatic Voltage Regulator)
The automatic voltage regulator automatically adjusts the exciting current to hold voltage regulation down to less than
3%. This helps prolong product life without damaging the electric devices.
DC Output for Battery Charging
The generator can generate a DC output (12V, 1OOW) while generating an AC output so that batteries can be charged
during AC operation. In this case, make sure that the total AC and DC output does not exceed the rated output.
Full Power Switch
me dual voltage type has a full power switch as a standard component. The rated output can be generated at both
12OV (11 OV) and 240V (22OV).
Output Voltage Waveform Close to Sine Wave
The output voltage waveform is close to a sine wave and is free of surges so that the load will not be damaged.
Resistant to Inductive Load
Exciting power is obtained from the sub coil which is wound apart from the main coil. This means less output voltage
fluctuations against load variation, and thus a steady level of power. This feature is effective particularly for induction
motors, for example, which are subject to sharp current variation.
100% Copper Windings
The windings are made only of copper having low internal resistance. This feature also helps improve generator efficiency and prolong generator life.
Easy Starting with Recoil Starter
No-Fuse Breaker for Troublefree Operation
-9-
14.
Ruggedly Built Frame
The box type frame is so ruggedly built that two or more generators can be stacked. Another convenient feature for
the Robin generators.
15. Wide Range of Options
The elctric starter type, wheels, and econo-throttle are availabe as options.

5-2 FUNCTIONS
5-2-l STATOR
-l-he stator consists of a laminated silicon steel sheet core,
copper wire which winds the core, and lead wires which deliver the power. The copper wire is wound into the main coil,
sub (auxiliary) coil, and DC coil. AC output power is taken
from the main coil, and DC output power from the DC coil.
The outside diameters and laminated core thicknesses of
various models are as shown below.

5-2-2 ROTOR
The rotor consists of a laminated silicon steel sheet cover
with a field coil wound arount it and cooling fans and slip
rings at both ends of the shaft. The field coil leads are connected to the slip rings and direct current (DC) to the field
coil turns the rotor and magnet. The tooling fans cool the
generator by drawing cooling air from the slip rings and discharging it through the fans.

5-2-3 BRUSHES
- - - --------An exciting current is supplied from the AVR to the rotor.
The brushes are made of carbon; and the brush-holders of
plastic. It is necessary to keep the contact pressure between
the brushes and slip rings withing specific limits. Thus, care
must be taken of brush length. (See
9-3 BRUSHES.)
5-2-4 AVR (AUTOMATIC VOLTAGE REGULATOR)
The automatic voltage regulator employs an electronic circuit to automatically regulate voltage.
5-2-5 VOLTMETER
The voltmeter comes in two types, a 150V maximum type
and a 300V maximum type. Type voltmeter indicates
generator output voltages. The generators with a generated
voltage of 1 lOV, 120V type and dual voltage type use the
15OV maximum type voltmeter; and those of 22OV, 23OV,
and 240V type specifications use the 300V maximum type
voltmeter.

5-2-6 NO-FUSE BREAKER
The no-fuse breaker prevents AC output overcurrent and
shortcircuit overcurrent.
Some models have one no-fuse breaker, and the others have
two. The single no-fuse breaker protects the generator from
maximum current; and the double no-fuse breakers protect
the generator from maximum current, and its receptacles.
If the generator is operated for long above the maximum
current, the internal temperature of the generator abnormal-
ly rises to cause insulation deterioration, burning, electric
NO-FUSE BREAKER
shock, and electric leakage. The no-fuse breaker protects
FUSE HOLDER
the generator from such troubles. The receptacles and AC
F&. 5-8
plug have their own rated capacities. (Refer to
5-2-8 RECEPTACLES AND PLUG.)
If they are used above the rated
current, insulation deterioration, buring, electric shock, or leakage can occur.
These troubles are prevented by the no-fuse
breaker.
Table 5-3 shows breaker capacities and protecting objects.

2P2E means the bipolar doubleelemenr type, and if either of tw pairs
of currents running through tie no-fuse breaker exceeds the rated current, the no-fuse breaker operates to turn power off.
The 22OV. 23OV, and 240V types use tie two pairs connected in series,
and the 1oOV and 120V type have them connected in parallel.

5-2-7 FUSE
The fuse prevents DC output overcurrent and shortcircuit overcurrent. If the generator is operated at a level exceeding the
maximum current, it can cause insulation deterioration. burning, electric shock. and electric leakage. The fuse protects the
generator from these troubles.
Fuse capacity: 1 OA
5-2-8 RECEPTACLE
and AC PLUGS
These are used for taking AC output power from the generator. A total of five kinds of receptacles, each varying in rated
voltage and current from another, are used. Each model has at least one receptacle to deliver the rated generator output.
As many AC plugs as the receptacles, each matching the corresponding receptacle, are provided. Table 5-4 shows the rated
current for each receptacle. Be careful not to use the receptacles and AC plugs beyond the specified limits to prevent burning.

5-2-10 FRONT COVER
The front cover is an aluminum die casting and is mounted
on the main bearing cover of the engine. It has vents to discharge cooling air from the generator and the vents are designed to prevent fingers from entering.
