Small steppers?

[cnczoner]

Anyone know a good source for small steppers? Nema 8, Nema 11, or perhaps Nema 14 should be fine.

I found some at Anaheim automation, but want to make sure I've covered/compared a few sources rather than going with the first I've found.

Cheers,
-Neil.

Gizmo's surplus in Hillsboro Oregon has a whole bin full of small steppers about 8.00 ea. they do internet sales but I don't know the site

Would def not work for me then. I'll need specs, etc too, rather than surplus.

Hi ;
Please email stack size that you prefer for size 8, 11, 17 , I can get you very good pricing for three motors.

Let's say Nema 11 or 14 (though not sure why you did not mention 14). I need dual-shaft with a max shaft length of about 2.5" (because I'll be drilling all the way through the shaft). About 10 oz-in (give or take) should be fine. With these specs, it will probably have to be single-stack... ???

Cheers,

BTW, if you can get steppers with hollow shafts, that would be nice.

Hi Neil;
We have supplied 17, 23 frame stepper with hollow shaft. We need to discuss, get all the specification before quote is made.

Somehow I missed this response. I've finally CAD'ed the parts I'm making and it'll have to be NEMA 11 (single solid shaft, torque > 9 oz-in) and NEMA 8 (dual hollow shaft, torque not critical). If the hollow shaft with the NEMA 8 is not available, I can (try to) drill it myself.

I'll need about 2 of each.

Cheers,
-Neil.

Hi Neil;
I got your message, it is very difficult to get hollow shaft on size 8 as the motor shaft is 4 mm. If you try drilling yourself without proper procedure you can damage the motor. I will check with plant we can get hollow shaft. I would like to know the id of the hole you desire.
As far as other motor we can help with Nema 11 single shaft which is in stock.

No prob with the hole on the Nema 8 as I've found a workaround to that, and in this case, it can be single-shaft. That should make it easier to source now.

Ugh bummer -- I was hoping you'd come in at a lower cost. I have one other lead I need to go investigate, so I'll let you know. Thanks!
