I've seen a setup with an AC motor. Also on the shaft was a clutch and
diesel motor. The flywheel had to last long enough to get it started.
I remember tales of a system having troubles keeping time. It was traced
back to a 50-60 Hz converter box that wasn't putting out 60 Hz. Things got
better when they gave it a tuneup. That was back in the '80s. It seems
strange now that there were power supplies that couldn't handle 50 Hz.
These are my opinions. I hate spam.
