Re: hi-freq motors[perske etc]CAUTION!

-Your basic 3phase induction motor can literally EXPLODE,!!like a
grenade sending shrapnel every where when turned too fast!
I have read/heard that a quality 2hp 3phase can be driven safely to
120hz after that ???

High spindle speeds with direct drive, and no motor brushes.
At 60 Hz, you are limited to 3600 RPM. At 600 Hz, a 2-pole
induction motor will run close to 36,000 RPM. If you need
to go faster, just up the frequency (and voltage).
