nice item, I ordered it and under use for more than 4 months, so far so good

This stepper motor is very nicely built. It has ball bearings on both ends of the armature. There is no perceptible radial or axial play. When the shaft is rotated by hand without power applied, the magnetic "cogging" effect felt is very uniform, indicating good internal alignment and precision.This motor is listed as a "2.8 amp" motor, but they don't mention the voltage. That voltage is 5 volts.I ran this motor using an Arduino microcontroller with a motor driver board (dual H bridge, not a stepper board) and a few lines of code to sequence the motor coils.The motor driver board was connected to 12 volts DC through an 8 ohm, 20 watt resistor. This makes use of the coil inductance and decreases the rise time of the coil current and makes the motor more efficient. It also serves to limit the coil current when the motor is stationary and the motor driver is left enabled).The motor runs great... nice and quiet in both full step and half step mode. I didn't measure the actual output torque, but I can tell you it takes a very strong grip on the shaft to stall it (which is WAY more than my application needs).Nothing bad to say about it. I'm completely satisfied. Both thumbs up!

have had no problems with this stepper, bought to replace a unit that crashed (along with the driver)I would purchase this again.
