Need info on converting my 8x30 knee mill to VFD servo

[TNSharps55]

I am a home hobby machinist and I have a Jet 830F 1.5 hp knee mill from the 1983 that I'd like to convert from step pulley spindle drive to servo drive. The mill is essentially the same as a Grizzly G0731 8x30 knee mill. I know absolutely nothing about servo systems and would like to get advice on what kind of systems or kits to consider. The mill is wired 220V single phase and I would like to keep that with the new drive system.

I don’t know if you want servo or a 3phase motor with a VFD. Many here have done the 3ph/vfd. Check your motor name plate for frame size and shaft size. Find a comparable 3ph motor and add a suitable vfd. Search the forum you will find lots of examples.

My shop is single phase so I'd prefer to stay with that so I don't have to do a phase converter. My frame size is 90L.

The thing is the vfd takes single phase and makes 3phase to the motor. Some will take 120vac and output 220vac 3phase, usually 1hp or less. More hp will need 220vac single phase. So you should have the power you need already.

Your 90L motor is an IEC metric motor, 2hp. Below is a motor chart. It has the dimensions of your motor.

I sincerely appreciate the info. From what I've seen and been researching, it sounds like the VFD 3 phase solution is the way to go.
