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 de- liver 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-

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 RING rings at both ends of the shaft. The field coil leads are con- nected 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 dis- charging it through the fans. BEARING ’ Fig. 5-3 I’ c----l---- II- Fig. 5-4 RGX240 MODEL /

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.)

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 push- ing the button in. The circuit breaker is a thermo-sensitive i type so. if the temperature inside the circuit breaker is stil

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.
