so, after wanting a milling machine for a few years, I broke down and bought one - this one
You will notice that it says it's 440V - I don't know if the motors, etc are dual voltage or not, but my garage doesn't have 440 in it. Of course I can use a transformer and a bunch of VFDs or a rotary phase converter, or .... but I wonder what the group experience might be. I can also rewind the motor for 220 and use an off the shelf VFD, or I can modify a 440V VFD so it accepts a DC input and then make a DC power supply (e.g. full wave doubler) to supply it from the 220, or .......
so, what do you think?
