Motor advice

I think this is one for Bob!
I cannot afford to change the motor on my Wade metalwork lathe just yet but would like to decide what I am looking for and keep my eyes open for a possible replacement. Here is the plate on the current motor, sorry about the odd angle, it's not that easy to get to.
So it's a 1HP single phase 4 pole motor, I checked the speed of the spindle with a cheap optical rev counter, which has now eaten it's battery (that explains why it was disconnected when I got it out of the drawer).
It claimed it was doing 1128, which I think is a bit fast as the slowest of the direct speeds on the lathe.
I plan on fitting a 3 phase motor with an inverter to give variable speed control, like I have on my Jet wood lathe. I think a 1 HP motor should but OK, the question is would a 4 pole like being run at half speed or less when cutting metal, or should I look for a 6 or even an 8 pole motor?
