I was currently running my Kmg-TX on 118v but now that I bought a new shop going to 220v how much amperage do I need? 50 like my welder? Want the correct size wire and breaker installed. Sorry unable to find my paperwork after moving.
Generally, power equals volts times amps, so at twice the voltage the system will draw half the amperage. Based on the motor name plate, the full load amps of our 2hp KMG-TX motor is about 6 amps. Amp draw must be more than that at low RPM/high torque situations and under very high loads, so it's possible that a 20A breaker may be appropriate at 220v. Check with an electrician since the proper breaker will depend on expected usage, wiring, shop configuration and what else is wired and running on your circuits.
Beaumont sells the KMG-TX with either a 2hp motor or a 3hp. The VFD for the 2hp KMG-TX can be powered by either single phase 115v or 230v AC, and the motor wiring is the same in both setups. The important change for the 2hp KMG-TX grinder is to change the internal VFD jumper J1 to match the input voltage. No motor wiring change is needed if you went from running the 2hp KMG-TX on 115volts to 230volts. The VFD for the 3hp KMG-TX can be powered only on single phase 230v AC.
This motor receives 230 volt 3-phase power from the variable frequency drive or controller. The motor wiring shown in this video is "low voltage" for this particular motor, which can receive either 230v or 460v from the controller. The controller from Beaumont can be set to receive either 115v or 230v power in single phase.
Great job, makes setup very clear
Great to hear!

Then I believe that I saw a layout for returning the wiring in the motor on the website back to 220v .

Is this for 110 or 220? Sorry if it says
