Kysan 1124090 NEMA17 Stepper Motor

I bought these to replace a set of smaller Z axis motors in my Prusa i3 3D printer that were having trouble with the weight of the X carriage assembly. These motors had no trouble at all. I'll buy them for my next printer too.

I bought these stepper motors for a robotic device I am building. Kysan makes good stepper motors. The only problem I ran into was finding the pin-out. I ended up connecting an ohmmeter to find the two coils, and having to reverse the leads on one coil. Not hard, but I shouldn't have had to waste the time.

I ordered three motors and they came in one box without any other packing material. The cases were all dinged and scratched and I had to return one because one of the cables had been pinched and the wires were exposed. The other two work fine.

Great motors for any RepRap project. Plenty of torque, comes with connectors with long wires, and a D-shaft to mount on pulleys securely.

Nice strong motor. Good upgrade from stock x and y on my Hictop Prusa i3. Be aware that these are slightly longer than the standard 45's that are included in most kits. And, they can still get toasty with too much current. Make sure to re-adjust from your previous settings as these may give better holding with lower current than what you set up for your old motors.

The defacto standard steppers for 3D printers. The wiring harness is quite long and the motors are well executed.

Excellent. Everything went as expected. Stepper motor came on time and works as it should. I would recommend. I used this to replace stepper motor on my Printrbot Metal.

Great motor for a prusa mendel. these are a little higher power than my last set of motors and I can run my printer faster with no skipping steps. highly recommended.
