Converting a 12x36 lathe to 3-phase power.

Yes, that is a good point John. Smiley-eatdrink004

If you run the motor too slowly - for too long, they will overheat since the motor cooling fan blade slows down as well. Work on and off for short periods of time in order to let the motor cool down between times, or set up an additional external fan to help cool the motor as it runs.

They do make special inverter duty motors that have a separate motor and fan built in to handle that, but they are somewhat expensive.

Just use common sense and keep an eye on the motor temperature if you are using a standard TEFC motor.
