Re: [CAD_CAM_EDM_DRO] Re: Single Axis Control

Earle

A couple days ago I replied to your query but wanted to expand on a single axis motor with an integrated driver.
I suggested something like this (read below)but your torque requirements maybe higher than a motor like this can provide.

Motor with driver for stand alone operation: ~$50 (this motor)
Computer to program motor: (if you have a computer) $0
Power supply:~$50

At the lin engineeeing website you can find all you may need under their "integrated motors" page.

I don't work for them, but I have been to their facility, seen programming of these stand alone motors drivers and have been very impressed. I am looking for a reason to buy one of these things to automate something at my work.
I hope this helps.

The cheapest programmable counter I've noticed is the Automation Direct unit with dual outputs. That's handy if you want to slow the frequency generator at the end of the process.
