AFAIK, they are Wantai Motor 57BYGH218, and you can find the specs here: http://www.wantmotor.com/ProductsView.a ... =75&sid=80

There was a photo with a legible label posted on the forum, but I can't find it. The '218 matches the 2 A spec and the apparent 51 mm length, so it's very likely the right one.

Edit: found it: http://www.shapeoko.com/forum/viewtopic ... 587#p47583 -- and yes, it's the 57BYGH218 (the -1 suffix refers to the custom wiring and connector and does not affect the other motor specs).

Sorry for the silly question!!
Our motors with shapeoko 3 are 2.6V, the ones I can find on line are 3V. Can I use the 3V instead the 2.6V?
The specs are:
Step Angle (degrees) : 1.8
4-Phase
Rated Voltage: 3V
Rated Current: 2A/Phase
1/4" Diameter Drive Shaft
Holding Torque: 90N-cm (125 oz-in)
NEMA 23 form factor

Thanks again,
from a very disappointed shapeoko3 owner!!

Those motors will work fine. The voltage rating does not matter much, just the current rating.

Hi cvoinescu, I am back!
I have to replace one motor, my question is, is it smart to replace only one,( different brand) or is it saver to replace all fore?
I found a place here in Canada with the 3A motors for $25.- instead to wait for an answer from carbide.( it is only 3weeks :twisted: )

Replacing one should be fine. The SO2 would often be configured to have NEMA23 on X- and Y-axes, w/ a NEMA17 on the Z.

Replace either the X- or the Z- — I suspect it’s important for the Y-axis motors to match, the wiring length needs to so as to match resistance.

3 A is too much, you need a 2 A motor. I mean, a 3 A motor will work, but you won't get the rated torque, because the Carbide Motion board will only supply 2 A.

There's no reason to replace the good motors. Even on Y, it's okay to use different motors.
