Is 1.9mm diameter smal enough?I have an application for a tiny low-voltage, low-current,
synchronous motor. Any idea who makes such a thing? I was thinking
maybe the kind used in very small disk drives but I can't find a
manufacturer.

http://www.maxonmotorusa.com/products/The pager motors are nifty, but I need tight speed control (a
couple of thousand rpm), preferably without fancy speed control.
Higher voltage/lower current drive would be nice. As would a 10 year
operating life.
well, if money isnt a problem

There is a 'crossover' here in terminology. DC brushless motors, are in a
sense very similar to synchronous motors, but with the excitation phases
fed from a synthesised DC source, rather than a normal AC excitation. Most
drive motors are DC brushless designs, rather than synchronous motors.
For a genuine 'synchronous' motor have a look at SAIA-Burgess. Their 'URT'
series motors, are 13mm*11mm, and run of between 3v, and 24v AC.
EAD motors, do a DC brushless design in a very similar size.

You might try some links here:Probably rather sell the controller. It looks like I would have to
generate a 3-phase...pulsed DC? Where can I find info on driving
them?

They should help you with that.Price is "always" an issue.
The Maxon EC series looks very interesting. Small, low power,
and high speed. Maxon doesn't say much about driving them however.

What is the price range of the Maxon DC brushless motors?On Fri, 11 Mar 2005 16:00:30 -0600, in sci.electronics.design ROBERT

I've sent Maxon an email, but it's Saturday and I was just hoping
someone might have some numbers already and would post them to the
newsgroup, along with any other impressions of dealing with Maxon.
No Idea, havent used them since '93, servo motors on a motion control
