Power supply help

[bigvinney]

Im going to buy a Seig X3 mill and convert it to cnc. Im looking at http://www.homeshopcnc.com/page3.html 640 oz/in stepper motors (volts-2.3, amps-5.5dc) and using Gecko G202 drivers. I am converting all three axis right now but will add a rotary table in the future and would like to have the control box built for it. So my question is what specs for the power supply should I use? I was thinking about 50vdc and 15amps dc. Opinions please.


Thanks Vince

Check with Gecko and your motor supplier for specific recommendations - each motor varies on how much "over voltage" it needs/wants/tolerates.

Do a "power supply" and "stepper motor power supply" search on this website.

There was a recent post (it is not on past 24 hour post pull up) that outlines how much over voltage you could/should run when driving steppers.

You could probably get by with a 12vdc switcher out of a PC with a motor with that voltage/current rating. These cost peanuts especially if you use AT models as these can be found dirt cheap at computer shows/salvage houses.

And, yes they can be "stacked" to create 24 or 36 volts but THIS MUST BE DONE WITH CARE. Again, "power supply" site search will lead you there. (EDIT: go here: http://www.cnczone.com/forums/showth...t=power+supply)
