220-240V is typically single phase. 208-230V is typical three phase.

You can get static phase converters pretty cheap these days. If the motor is rated for inverter duty, you can get a variable frequency drive.

If you only have 120V available, there are VFDs for running three phase 208-230V motors, but you are limited in power.

A lot of knee mills are single phase, just check the motor nameplate.
