I just orderd the 3 axis board and would like some recomendations on which steppers work the best with this board.

Thx,
Rod

Any nema 23 motor that's 3-6 volts, 1-2 amps will work great. You should also be looking for a 12 or 24 volt supply. 24 volts works best (faster).

A lot of people use these:

Xylotex used to sell them.

Anyone know what are the highest torque Bipolar motors available that work with the Xylotex controller?

I see alot of 80 oz/in and some 100+ but haven't found any ones larger yet.

I've got some Powermax M22 series rated at 253oz-in at 2.3a bipolar series. I've seen some 34 size motors with a little more torque that would also work, that were around 300-350 oz-in.

[Beezer]

How do you find those Powermax are working for you and what size machine do you have them on?

BTW... What is the model number of those Powermax M22's? So I can check the specs on them and price.

Thanks,
Carl

Right now they are sitting in a box waiting for me to find some free time. But I did wire them to the Xylotex when I got them and they seemed to have a lot of power. I don't know the exact number, but they have the "B" windings and they have the low inertia rotor. Something like M22NRXBJxxx..., J is the low inertia. You can get them here http://new.kimcontrols.com/category/...fic-Scientific

[Beezer]

Thanks. I will have a look into them.

[Beezer]

Would these motors be a good choice to run off the Xylotex controller?

The links don't work

[Beezer]

Sorry about that. It is very strange. If you have the initial website open (first link above) the rest of the link will work then other wise they don't fr some reason.

I have edit the original post above so they should all work now, as long as you click on the first link to open up the initial website. I also added a couple more motor selections.

Thanks,
Carl

What about these Motors:
150 oz in (NEW) NEMA 34 (2.0 deg) motors (w/pwr resistor)for $60 ea.
150 oz in (surplus) NEMA 23 (1.8 deg) DUAL SHAFT (w/pwr res)for $40 ea.

What do you think about 2.0 degree?
Thanks.

[ger21]

Those don't link to a particular mnotor, they list a series of motors. Each series can have motors that will work with the Xylotex, but also motors that won't work. The motors need to be no more than 2.5a/phase, and the lower the voltage the better. That website doesn't seem to have a lot of clear information, so I can;t be much more specific.

[Beezer]

Yeah I noticed that too about the website.
I sent an email to one of Pacific Scientific's
retailers here in Canada with my specs so we will see what they come back with as for motor suggestions.

[ger21]

They did have a link on there site to the .pdf I posted above (the one on the Xylotex site). But it also looks like they now have some more powerful 23 size motors, up to 380 oz-in. What kind of machine are you going to be using them on?

[Sanghera]

Oops sorry. I wasn't thinking right there. I don't really know the specs for these motors, but they come from the Stepper World Site.

[Sanghera]

Thanks.

[Beezer]

They will be going on a CNC router that I want to build but it's just in the planning stage right now so I am not sure what the finally size will be but will most likely be smaller at first to see how it goes then build a bigger one later. I would sooner now get motors that will end up going on the larger machine late rather then buying small ones now then having to buy new ones later. The Z axis I will build now will be large enough and more than enough travel to be easily put on a larger machine in the future. Only thing stopping me from building the larger machine now is the cost of a pair of long linear rails with carriages plus space but in the end I would like to have a machine that is 48" x 24".
Maybe these motors are overkill and some with 150 oz/in would be more then enough. I will be using ballscrews on all axis.

Carl

[ger21]

What size ballscrews? If you're using the 5/8" ones like everyone else does, I'd get bigger motors, as the 5/8" screw needs a little more power to turn than a 1/2" or smaller screw. Depending on if you can find them, I'd look for something in the 200-225oz-in range. Are you looking to buy new ones? You might want to look at these Vexta's
http://www.orientalmotor.co.jp/cgi-b...frameSize=56.4
Although they're rated 2.8a bipolar parallel, they'll probably still work pretty good at the 2.5a the Xylotex can deliver

[Beezer]

The ballscrew I have for the Z axis is a 5/8" and that is only because I found a cut-off piece of it at work which is long enough to work on the Z axis. Just had to buy the matching nut for it. I picked up
47" long SKF 12.7x12.7lead ballscrew off ebay which I was planning to use for the X axis or if that wouldn't work for the Y axis.
Still need one more ballscrew.
