Vfd and motor change

The name plate is covered by motor mount but it is a GE 3/4hp 1750 110 CW and CCW
 
You must have an ac motor there if you are just plugging it in- a dc motor would require, at the minimum, a bridge rectifier between the wall power and the motor, probably mounted in a little box somewhere on or near the forward/reverse switch (if there is one)

No box. Just plug in and turn on
It does have a foreword and reverse and neutral barrel switch on the mill. Reverse dont work. The motor is not original thank you. What do I need to do

Agreed. However a rectifier could be fitted inside the reversing barrel switch. That would be weird, but possible.

Seems to me more likely an A.C. motor. Without pictures to confirm it's DC, I will have to withdraw my (much cheaper and easier) suggestion of installing a DC drive.

So, you will need to go out and buy a 1hp 3ph motor, 1800rpm 230v, and a VFD 1hp 230V, rated for single phase input. For the motor I would check surpluscenter.com and for the drive, teco or automationdirect.com
 
Thank you for all your help. I appreciate it thank you all . I will give a update soon I hope
 
I did a video overview of the DRO installation on my 8520 but I also show the Fuji VFD that I installed. I set the VFD to vary the motor speed from 900 to 1800rpm, and it has plenty of low-speed torque, but I can always rearrange the belts if I want to go really slow (or fast). I added an external braking resistor so that the VFD can stop the spindle quickly and left it hanging in the video, but I cleaned everything up since then.
