2) Cleaning Slip rings
The slip ring surfaces must be uniformly
bright. Slip rings showing black spots,
excessive wear, or uneven wear must be
repaired. A stained slip ring lowers generator
efficiency and output voltage. Polish the
slip rings with fine sandpaper while turning
the rotor until rough spots disappear. Care
should be taken not to touch the rotor coils
with the sandpaper.
6-5 BRUSH
The brushes must be smooth where they
Contact the slip rings. If not, polish smooth
the brushes with sandpaper. A brush that
is not smooth produces arcs between the
brush and slip ring leading to possible damage.
Usable brush lengths are from 5 mm to 15 mm
[0.2" to 0.6"].
A brush shorter than 5 mm must be replaced
because decreased contact pressure between
the brush and slip ring lowers generator
efficiency and output voltage.
6-6 A.V.R (AUTOMATIC VOLTAGE REGULATOR)
1) Features
This AVR operates to control the field current
in order to maintain the output voltage for the
AC current, which generated by the magnetic
flux by the field coil.
2) A.V.R. trouble may be identified by simply
looking at the A.V.R., or by the inter-lead
resistance with a tester, or actually mounting
it in the generator and operating it.
