Scotty,
I would have thought so, too, but I saw the aftermath of a 400HP/1750 base speed motor eating a set of brushes after developing a severe high/low comm bar condition (up to 1/8th inch bar-to-bar!). This was on a plastics extruder screw application, and occurred during a production run, so at a minimum the screw/barrel frictional load was still there when it happened. The drive was an old engineered Reliance MaxPak (pre-MaxPakPlus).
It took me a while to arrive on the scene (my car decided to break down on the way to the plant), and it happened in the late 80's, so my memory is a bit fuzzy, but I recall the field controller had failed, measured field resistance was congruent with the nameplate field current & voltage, and field insulation resistance was OK (several hundred of megohms).
After the motor was replaced I checked the tach loss shutdown, and it was set to a hair under 2000 RPM.
My only speculation as to how this level of motor damage occurred sounds a bit nuts, but here goes - the field controller didn't fail 'cleanly', but rather went to zero output for some span of time (and the motor sped up, but not up to the tash loss/overspeed level), then re-established field current for a time before failing complete (essentially, trying to drop motor speed back to normal levels instantaneously), and it was this abrupt change in velocity at near full speed that threw the bars. Yep, still sound nuts ... I've never been able to come up with a satisfactory answer.
That said, in extruder screw applications drive setup on older analog drives is often done with the motor uncoupled to prevent excessive wear on the screw and barrel (no polymer; no screw lubrication), and must be done very gingerly, and with full knowledge of the bad things that can happen.
