Can anyone suggest a motor?

If you want to run for long periods then go for an induction motor, only down side is tehy tend to be on the large side for the same power as DC.

So you want a cutting spindle basically.

Have you thought about a round belt drive as used on the old engravers

Tony at lathes.co.uk supplies the belts made to measure

Something like this in the attached poor quality picture


Very quiet and can run all day this is from a Taylor Hobson i was going to mount it on my mill for engraving, but i might get a water cooled spindle instead, it will be clamped in the middle part


Criticism i looked at your machine build and you really should protect the ballscrews from dust ingress.

I have already built the spindle, its the motor that I need. Yes I could cover the ball screws but with what? It would require some expandable material where do I get that from?

Alan AC motor will run all day

As for screw covers the company i got my telescopic ball screw covers sell them

For wood dust you need bellows type http://www.dqr.co.uk/bellow_covers.html
