<div>So, a bit like <a href="https://www.banggood.com/search/990669.html" target="_blank">https://www.banggood.com/search/990669.html<br>
</a></div>

<div>Looks like the standard length is 34mm,
colours may be standard, and weight is 220g. Allowing 12g for your
gear, this all sounds very similar..</div>
<div><br>
</div>
Your part number is D42HSC1413B-24, so it looks like the D42 part
could be associated with faceplate size.
<div><br>
</div>
<div>googling "d42hsc" stepper motor
indicates that d42hsc may be the family of the part you are
looking for.</div>
<div>
<div><br>
</div>
<div>The DC resistance of the Bangood part
above is 2.1ohms per phase.<br>
</div>
<div><br>
</div>
</div>
<div>If you can measure low resistances with
accuracy, see what your resistance is for one phase. Or pass 200mA
through a phase and measure volt drop.</div>

Michael,<br>
<br>
Welcome aboard.<br>
<br>
A few parameters which may be useful:<br>
<br>
- How many wires, what colours<br>
<br>
- Overall dimensions<br>
<br>
- Weight<br>
