The motor has the needed power to move my Z-axis. I replaced a NEMA 17 motor because the NEMA 17 would sometimes get out of step. This motor has even working well.

Motor is heavy duty.

A bit low torque, but not a bad value for the money.Very well built - good craftsmanship!

Cant get this thing to reverse, but it may be my code on the arduino. Getting very frustrated.

I hooked it up and didn't work, must be a return. I checked the windings and 1 had no continuity, the other had a high ohms value. Just wondering if there is an warranty.

I ordered these stepper motors to fit a linear rail/ ball screw kit that comes with a 10mm to 6.5mm coupling so I ordered these stepper motors to fit. I had to delay my build for a little while and when I went to assemble I discovered the steppers I ordered were incorrectly listed with 6.35mm shafts.

The motor will run at full torque to 350 RPM. I use a 48v supply and drive at 5.6 amps. This extra current gives much more torque but require a 120 mm 48v fan to keep the motor cool. I am very pleased with the result.
