5-2 FUNCTIONS 5-2-l STATOR The 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 (.ausiliary) coil, and DC coil. XC output power is taken from the main coil. and DC output power from the DC coil. (DC coil is installed on Models RGX240 .md RGXIOD only.) The outside diameters and laminated core thickness of various models are as show below. Fig. 5 I Fig.
5-2-2 ROTOR FAN The rotor consists of a laminated silicon steel sheet cover with a iield coil wound arcund it and cooling fans and slip 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 cooling fans cool the generator by drawing cooling air from the slip rings and discharging it through the fans. BEARING ’ Fig. 5-3 I’ c----l---II- Fig. 5-4 MODEL d (mm) (In.) I (mm) (in.
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 within specitic limits. Thus. care must be taken about brush length. (See 9-3 BRUSHES.) Fig. 5-5 5-2-4 AVR (AUTOMATIC VOLTAGE 1 REGULATOR) The automatic voltage regulator employs an electronic circuit to automatically regulate voltage. L J Fig.
5-2-6 CIRCUIT BREAKERS Models RGX180 and RGX240 have a pushbutton circuit breaker and Model RGX240D two pushbutton circuit 1 breakers. Nomrallp, the pushbutton circuit breaker is closed with the button pushed into the panel to keep the circuit : live. If an overcurrent runs. the button comes out to break the circuit. The circuit can be closed again by simply pushing the button in. The circuit breaker is a thermo-sensitive i type so.

5-2-11 REAR COVER The rear cover is also an alumrnum die casting. and has a faucet joint to hold the stator together w-ith the front cover. It has bosses inside for holding the brushes, and slits for taking cooling air in. The slits are so designed that htrman fmgers will not go in.

The RG Series 1sthe revolving armature type. and the RGX Series is the revolving field tk-pe. The differences between these types and then features are described below. The constructron of the revolving armature t>-pe is shoxn in Fig. 5 -15. and that of the revolvmg field type in Fig. 5 -16. The basic operating principle of the generator is this. As a conductor moves in a magnetic flus (between poles S and S of a magnet). a voltage is generated in the conductor and can be taken out as electric power.
5-3-2 PRIMARY EXCITING ACTION The RGX Series employs an exciting coil in the engine magneto for raising the primary voltage. This action is explained. The RG Series generates a voltag2 when the generator IS started again because of the residual magnetism remaintng FC in the yokes and poles. If a generator of this type is disas- r-----1 I sembled and stored for a long period of time. the residual magnetism. may dissipate so that the generator may not rc& generate a voltage when it is restarted.
5-3-4 DUAL VOLTAGE TYPE (RGX240D) The dual voltage t)-pe can generate two Foltages from a single generator. It comes in two varieties: 12OV~‘11OV and 1lOV!ZOV. The circuit is shown in Fig. 5-l 8. Each of MC1 and MC2 generates an AC 12OV (or 1lOV) with the same phase, which is one half the rated output I voltage. This model has two receptacles to output one half of the rated voltage from each of the receptacles (112OVor Fig. 5- 78 1 lOV,.
5-4-2 CONTROL SYSTEM The control parts are certainly located to permit centralized control at the top of the engine. The parts added or changed are as shown in Fig. 5 -20.

9-3 BRUSHES The brushes must be smooth where they contact the slip rings. If not. polish the brushes smooth with sandpaper. X brush that is not smooth produces arcs between the brush and slip ring leading to possible damage. Usable brush lengths are from 5mm to ljmm as shown in Fig. 9-3. .a brush shorter than 5mm must be replaced because decreased con- 15mm - 5mm tact pressure between the brush and slip ring lowers generator efficiency and output voltage.

Devices such as that shown in Fig. 92 are necessary for checking the circuit breaker if it properly operates. The rated current is shown on the side of the circuit breaker.
