equipment |
- Electronic dynamometer
It is important to periodically check the pressure applied by the
brush-holder system and to evaluate particularly the variation of
the pressure along the same line of brushes. Three probes of varying
dimensions adaptable to fit the equipment, allowing measurements up
to 10, 20 or 60 N are available.

- Stroboscope
It allows easy location of run-out faults causing high brush vibration
on highly distorted slip rings or commutators. It is capable of dynamically
revealing mechanical, electrical and atmospheric faults. It allows
visual examination of the slip rings and commutators on electrical
machines while they are running .
