P.S. Just in case the humor above is misplaced. I don't want to
confuse you. You just need a REGULAR AC induction motor.

Ballendo,

I don't recall this point being covered. How much over speed would you feel
comfortable with in regards to a REGULAR AC induction motor? I got a couple
of 3hps and a 5hp. All are TEFC motors, 1725 RPM I believe. I really don't
like going over 90 Hz. Suppose I could try 120+hz with a scatter shield over
them or something :)
