Ok well in the UK here we seem to work in newtons and from what I can see from this link:
http://www.techno-isel.com/Tic/H860/HTML/H860P006.html
1 lb/in = 0.1129848 newton/metres
So a 26lb/in motor would be a 3n/m motor.
This gives me something to work with. I have seen the prices of some of these motors and its amazing how much they cost, £600-700 for something of this type!
Now I have been looking at some specs and if I were to choose a motor of this type what sort of rpm would I be looking at...I have a choice of:
2400, 3000, 3700, 4000.
Im going to get some prices from this manufacturer.
Cheers,
Tom
