I anywhere in the network can not find the characteristics of these motors even geeteh.
Maybe someone knows the characteristics of these motors ?
In "Package list" listed 42SHD0217-24B 1.5A (U) steper motors or is it the same just with a different label?

I think you can contact the seller to confirm it.

They are different stepper motors. I also ordered the 42SHD0217-24 stepper motor on ebay and received 42HS3418-24B20.
As you can see in this picture, the 42HS3418-24B20 has almost 20% less magnetic sheets.

Also the coil resistance is 1,5ohm instead of 2,5ohm.
I cannot confirm, but I think the rated current is 1.7A

All this means less power.

if you use them on the printers like prusa series then I think they are no much difference, it can handle the torgue you want.

Yes, you are right. But I did not bought them for a 3D printer. I want to build other device.
And I spent 3 nights researching the difference between different NEMA17 stepper motors and decided to buy 42SHD0217-24.
After 3 weeks I received a different product (42HS3418-24B20).
To my surprise, is smaller and less powerfull than the one advertised.

Beside this page, there is no other reference to this motor available on the web.
There is no technical documentation or minimum specifications available.

What is the value for the nominal current?
How big is the holding torque?

I didn't find the info for this motor too...maybe you can try them first.

Hi everybody, my printer kit (prusa3 Acrilyc pro B) have this motor and for setting the VREF I must know the current date but in internet I don't found any information for this motor, can you help me?
Thanks and ciao
