I had a look at some in various catalogues. There's an amazing one
with 22.5Nm torque, 50--350rpm, but the downside is the price: 204 UKP
(306 US$)! There are some more modest ones that might do the job, but
they are all much more expensive than just buying the motors themselves.
btw, all along I've been converting all my currency ammounts to US$,
assuming everyone else could do their own conversions from there.
I didn't think until just now that there are other sorts of $ about.
I hope you guessed what I meant.
Robin.
