Bridgeport Voltage 3 phase to single phase

[JimDawson]

Thanks for all the feedback. I like the fact that many of these have been made to almost appear OEM. Is there a default pulley configuration when you go the VFD route? Do you leave the pulleys in a state where something close to maximum torque is produced at the spindle (i.e. motor gear reduction)?

Sorry for all the dumb questions...

Back in the day when I had a change belt mill, I pretty much left it in the 660 RPM belt position. Then adjusted the VFD as needed. If I needed more torque or or higher speed, then I would change the belt/back gear as needed and use the VFD for fine control.

You can now get a 120v vfd that will give you 3 phase 240v.
