Some experience
of working on DC drives is being shared here. Actually, many of the
observations made during the process of troubleshooting have to be really
"felt" by the troubleshooter and it is difficult to find a
"ready to eat" answer here. However, some clues can always be taken
from these observations. Over
years, technology has changed substantially, but I am sure, there are many
industries still depending on old equipment and trying to continue using it
for some reason or other. With advent of the technology in the drive systems,
repairs on "component level" also has reduced to a great extent,
but the suggestions here can still be useful to many. ( This refers mainly to
analog dc drives with discrete circuit components ) |
