    Tips: The difference between stepper motor and other control motors

    The biggest difference between a low cost stepper motor and other control motors is that the stepper motor receives a digital control signal (electric pulse signal) and converts it into an angular displacement or linear displacement corresponding to it. It itself is an executive element that completes the digital mode conversion. Moreover, it can be open-loop position control, input a pulse signal to get a prescribed position increment. Compared with the traditional DC control system, best stepper motor has a significantly lower cost and almost no system adjustment is required. The angular displacement of the stepper motor is strictly proportional to the number of pulses input, and it is synchronized with the pulse in time. Therefore, as long as the number of pulses, frequency and phase sequence of the motor windings are controlled, the required rotation angle, speed and direction can be obtained.

    Great closed loop stepper motor for direct drive.
    I needed a stepper motor for my Ender 3 Pro extruder upgrade, so I bought this one. This Nema 17 stepper motor was pretty much plug and play. Works great and runs cool and quiet. I will buy more.

    I’ll be ordering more!
    I bought a bunch of ATO Nema 17 closed loop stepper motors to replace the old ones and I am glad I did. These run so quiet and cool especially with stepper drivers! I’ll be ordering more!
