Hi guys i'd like to ask if these stepper motors: http://www.mpja.com/prodinfo.asp?number=17757+MS
will work with this controller: http://cgi.ebay.com/3-AXIS-CNC-ROUTE...#ht_5909wt_989

I already have the motors but i'm looking for a controller for them.

Ohh and if anyone can find out the torque of them.

Thanks.

Those motors are quite small, 12v 250mA unipolar with 6 wires.

The driver is a bipolar driver that will work up to 2.5amps, but fortunately your motors can be wired as bipolar too.

It should work, and the driver has a lot of extra capacity so you would be able to upgrade to bigger motors later and still use the same driver.

Thanks for answering

. that helps me alot so i wont have to worry about them not working.

my cnc maching that im building is quite small it should need about 50oz. of torque so i hope these motors are that big but i do have some on ebay that are 80oz. so if these arent big enough i'll get those .

Just a little input quickly. MPJA is a surplus distributor; this means if an item is out of stock (which those motors are), generally they are for good. There are a few decent motors on MPJA besides the one you posted that are quite cheap (generally around 75-130 oz-in), as well as lots on www.alltronics.com. Good luck!
