Dear Folks,
I want to use rabbit SBC for our embedded application. I wonder how popular the rabbits are? I certainly don't want to pick something that might fade out of market in few years?
Other comments about the rabbits? How rugged or reliable it is in outdoor environments?
Many thanks in...
Thank you for all your postings, folks!
I was out of town so I couldn't keep track with your updates.
If I have new questions, I'll get back with a new topic thread.
Many thanks again!
Dear Curt,
Thanks for the info. I'm fully convinced that AC servo is capable of our type of work.
I noticed that you work for delta tau. I actually used PAMC II PC for my master's thesis back in 1999. I took a traning in Delta Tau LAX. I was working with Steve Melici (?) and Ali.
It's a...
Thanks for all your replies!
I'm a little confused. I read from FAQs that vector drive can provide high torque at low speed and run stably at low rpm (such as crane applications). But blacksea mentioned "AC servo motor (with sine or vector commutation) ... have significantly better velocity...
Latest Updates:
We require about 20 in-lbs at startup (stall torque) and 4 in-lbs during regular operation (nominal 30 rpm).
The fundamental question is:
1. Can we find an AC servo motor to generate this much torque at stall / 0 rpm and and operate steadily at lower rpm (such as 10 rpm...
The application is a radar type of gyro mechanism (20,000 lbs) that tracks the sun. The pan/tilt rpm ranges from 10~80 rpms in normal operation condition and the rpms changes constantly, although very slowly. Under hostile weather conditions, the rpm goes to around 2,000, mainly to move the gyro...
One more thought: is DTC (Direct Torque Control) motor better suited for such application?
How populor is it to use DTC in industrial applications?

Dear Folks,
I'm looking for a motor solution that can:
1. Provide high power (2 hp) / torque at low or 0 rpm;
2. Rotate stably and accurately at very low (10~80) rpm;
3. Relatively low cost;
I read through the FAQ article of vector and servo motor. But I'm still not sure which one fit best...
