Mill motor - what type of motor is this ?

I have an Emco milling attachment for my Emco Maximat V10

When I got it the electronics were listed as dodgy and sure enough turning it on it caught fire

I've replaced the lathe motor with a spare AC servo I have here - not wanting to get into the original burned control unit nor fork out for a new motor for the mill I'm keen top learn about the motor there is on it - maybe I can use a spare drive (granite devices VSD-XE) I have here to run it ?

It has 4 wires coming from it - is this something easy to a. figure out what it is ? and if it is easy to figure out b. easy to drive/run ?

One pic attached - the rest here:

I've done a bit more hunting online since - although I agree with your deduction, turns out although it is induction its particular implementation is different from 3 phase induction motor...

clues:

- Burned control box was mostly just two large caps and a bunch of mechanical switching hoo hah
- It's a single phase system

The caps stay in the circuit whilst running ... the three wires are because the cap is kept away from the motor - nice and confusing huh

I found a spare motor cap at 5uF in the box of bits that came with the lathe - an emco parts list says it should be either 8uF or 20uF (it isn't clear) - the diagrams I've found so far also indicate this motor type is the correct one to look at.

I might just give it a go
