I haven't magaged to find economical servo amplifiers for the AC servos I bought about a year ago. I'm now planning on using DC servos instead since amplifiers for them are more commonly available, which meanst that the AC servos are for sale. I've put them up on ebay:
one 1 kW Sanyo Denki P5 100VACÂ brushless AC servo.
three 400 W Sanyo Denki P5 100VAC brushless AC servos.
Happy bidding !
PLEASE ADVISE AS TO YOUR RECOMMENDATIONS AS RELATED TO THE MOTOR REQUIREMENT. THE MOTOR SHOULD BE COMPACT, OR EVEN A PANCAKE STYLE.. RPM BETWEEN 800-1000, I CAN USE A BELT REDUCTION IF HIGHER RPM IS CHOSEN. APROX HORSEPOWER 1/4 - 1/3 13.9 INCH POUNDS. 120 VOLTS IS PREFERABLE, DC AND CONTROL COMBINATION IS ALSO ACCEPTABLE, BUT COULD BE COST PROHIBITED.

Hi Jerry,
I'm not an expert on electrical motors, and I can't really figure out what specific information you are looking for...
Check out cnczone and talk to people there, you should be able to get a good idea of what torques are required for a mini mill (that will depend a lot on if ballscrews or acme screws are used).
