DC drives, common problems and troubleshooting |
|
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 ) |
