thank you Craig
I found this ( New Leadshine Hybrid servo Drives HBS86H work 24-80VDC or 18-60 VAC fit the servo motor 86HBM80-01-1000 out 8NM power 400-500W) [ US $195.32 + DHL Shippng 95$USD]
(stepmotor induction=3.73mH current=6Amp)

I don’t have the time to look up that drive but I’m not really sure I’d go this route. Much of what one buys depends upon ones budget and ones expectations. If the goal is cheap go with a good stepper drive and stepper. If the goal is high performance then look at AC servos or DC brushless.

Also realize that a servo implementation is a bit more involved then adding a stepper to a machine. If you don’t have experience with servos I’d suggest sticking with steppers. When run properly steppers will produce good results.

It's about the same price as regular stepmotor+driver
BTW Are there any missing parts that I did not mention?

This is where almost everybody ends up marking last minute purchases. Frankly there are dozens of items that you have mentioned that I’m not sure if you know about. For example building a proper control box for the electronics requires dozens of parts beyond the box to put everything in. Wire and cabling adds up as do fuses, switches, E-Stops and the like. Don’t forget drag chains or other cable management solutions.

Mechanically you have the same issue, dozens and dozens of items that have to be built into the cost. For axis with lead screws there are screw supports, bearings, couplings, belts and pulleys brackets & etc. the same applies for the rack driven axis. Then you have hundreds of screws and bolts to buy. In a nutshell you need to consider everything that makes a machine work.


This is just a quick response I’m sure others will find significant things I missed. In the end the bigger the machine the more you have to buy.
