Where do you get your servo motors and gearboxes? *I'm working on a

I'm looking at Anaheim Automation (which is, I assume, a reseller for
cheap Chinese stuff) and Teknic (whose prices are amazingly close, and
whom I've brushed up against in other contracts, and seen them highly
rated). *I'd be very happy to find more, particularly if the company
actually makes an effort to control cogging and other parasitic torques
down.

I'm looking for brushless motors and right-angle gearboxes with dual
output shafts that are pretty efficient (i.e. no worm gears!) and can
take some side loading.

Looked at these for a project but never used them.

If cogging is real important one might try a 3 phase induction motor
and a motor controller. We have project that uses this aproach will
good results. It wont be snappy but it will be smooth

This is what I use professionally

in contrast to the popular conception supported by newspapers
and mothers of Leftwingers, a goodly number of Leftwingers are
not only narrow-minded and dull, but also just stupid.
