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 de- liver 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. Fig. 5-1 Fig. 5-2 RGX305 RGX405 1 RGX505 MODEL RGX305D RGX405D 1 RG

FAN 5-2-2 ROTOR The rotor consists of a laminated silicon steel sheet cover SLIP RING with a field coil wound arount it and cooling fans and slip 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 tooling fans cool the generator by drawing cooling air from the slip rings and dis- charging it through the fans. BEARING Fig. 5-3 Fig. 5-4 RGX305 RGX405 RGX505 MODEL I RGX50

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.) RGX405. RGX405D RGX305.
