If you're not comfortable messing around with electrics, I'd stay away
from the "treadmill" motors that offer variable speed. They require
electronic controllers, and the ones that come with them often crap
out -- then you have the problem of "now what?"

Thanks. I was wondering about those.

Go with an induction
motor of the same speed as the original motor. Induction motors come
as 1725 RPM (or so) and 3450 RPM (or so). Yours will very likely be
1725 RPM.

The motor on my lathe runs at 1140 RPM. The space won't allow for
pulleys
appropriate to use a 1725 RPM motor. Any ramifications or considerations
about 1140 RPM motors?

Choices a

1: find a suitable 1140 RPM motor or rebuild the one you have
2: modify the space available
3: use a threephase motor and a VFD -- rotsa ruck with that if you're
not comfy wiht electrics
