4.FUNCTION OF EACH COMPONENT

4-l GENERATOR

4-l-l STATOR

The stator consists of a laminated silicon steel

sheet core, and a copper coil wound around the core with a lead wire from which AC and DC output are taken out. The copper wire coil consists of a main coil and a DC coil, and AC output is taken out from the main coil, while DC output is taken out from the DC coil.

4-l-2 ROTOR

The rotor consists of a laminated silicon steel sheet core, a field coil which is wound around the core, and a cooling fan mounted on one end of the shaft, with a slip ring on the opposite end. One end of the lead wire from the field coil is connected to the slip ring. The field coil becomes an electromagnet when DC current flows from the slip ring. The cooling fan is for cooling the generator by inducting cooling air from the slip ring side and discharging it from the fan side.

4-l-3 BRUSH

Exciting current from the AVR is supplied through this bush to the rotor. The brush is made of carbon, while the brush holder is made of plastic. In order to run the generator efficiently without failures, it is necessary to maintain the contact voltage between the brush and the slip ring within a range, which needs management of the brush length.
