This stepper motor from Banggood is as pictured on the web site. I have not done any electrical test yet but the fit and finish of this unit is quite good. Note that the motor shaft is full round. It does not have a flat for a grub screw. I prefer a shaft that has a flat as this allows the grub screw to lock better and should you need to remove the gear or pulley that you have mounted on the shaft, there are no "burrs" from the grub screw that might make it difficult to remove the gear. This is a small issue, I will probably just file a small "flat" on the shaft where the grub screw will hit. Overall, I am pleased with the motor...now to hook it up and run it.

I haven't tested these yet,but they appear to be good. Each one came individually wrapped on foam with another layer of foam wrapped around the whole lot. Unfortunately this was not taped up very well and some of the motors slipped out and were rolling around loose in the plastic package. Fortunately there was not damage as far as I can see,

Haven't yet tested, but it looks even better than the pictures. The upper and bottom cup looks to be CNC crafted and it's shiny. This feels to be solidly built.

This is my second order for this stepper motor. First one worked very nicely so I bought 2 more for my 3D printer build. Motor leads are about 30 cm (12") long, stripped but no connector...it would be nice if they were longer. The motor shaft does NOT have a flat on it, it is fully round. I filed a small flat spot on the first stepper that I tried because the extruder gear I was using had only one grub screw.

motor de passo Nena 17. ainda falta testar mas aparentemente é um bom produto com aparente boa robustez

Good product. Used on light duty printer to drive a ball screw. Works fine. I can not comment on heavy duty work.
