DC motors and AC short circuit analysis
DC motors and AC short circuit analysis
(OP)
When doing an AC short circuit study, do DC motors contribute to fault currents and therefore need to be included when building a system?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Such a drive usually has very fast acting (semiconductor) fuses which are current limiting. I do not think that your short circuit analysis will suffer much if you leave contribution from the DC motors out. Unless, of course, there are very large DC drives, and many of them.
