VFDs for such as your mill come in 115v and 220v single phase sources, your choice depending on your shop voltages. A second option is V/Hz or 'sensorless vector control'. V/Hz is the historical older type which has no compensatory feedback to boost the motor power at low speeds. The sensorless type VFD does have such compensation.
