top end of motor voltage tolerance
top end of motor voltage tolerance
(OP)
Apparently, military power generators are less than accurate. I have a situation where there's a 220vac 3phase motor being run by (approx)247vac and the motors are burning up....what would be the most reasonable (cheap, simple, easy to explain)way to reduce the voltage? I'm guessing I can't just put a big resistor in series....

However I would wonder why the "generator?" is putting out such a high voltage. You are probably stressing a bunch of other stuff too. Bucks for the motors may leave other stuff failing. See if the generator's voltage can be adjusted to the correct value. (Could be as simple as turning a screw)
Furthermore (still considering a generator) you should definitely check the frequency! A high voltage could be a symptom of over speed. This would mean your motors are all running faster than expected, which would mean they are being forced to do more work than designed for, and hence are burning up.
