    Tips: 2 main advantages of stepper motor

    1. Because the stepper motor is no brush, the reliability of this motor is high. Its life depends only on the life of the bearing. As long as the life of the bearing is long enough, the life of the entire device will be very long.
    2. The response of the stepper motor is only determined by the digital input pulse, which can facilitate the use of open-loop control, the structure is simple, and the cost of control is greatly reduced.

    Great Nema 34 stepper.
    I need a new Nema 34 stepper motor for my 3D printer. It is a very powerful Nema 34 stepper. It not only stayed relatively cool, it never missed a beat. Great stepping motor and does exactly what I need it to do.

    Working perfectly so far!
    ATO Nema 34 3 phase stepper motor works great! This motor came very well packed. I replaced my extruder motor with this one. More than enough power for my needs. Not missing a step. I will buy more products of this brand.
