    Tips: Difference between stepper motor and AC servo motor

    The stepper motor is a discrete movement device, which is essentially related to modern digital control technology. With the advent of all-digital AC servo systems, AC servo motors are increasingly used in digital control systems. Although the two are similar in control mode, there are differences in performance and applications.

    • Different control accuracy
      The step angle of the 2 phase hybrid stepper motor is generally 3.6°, 1.8°, and some high-performance stepping motors have a smaller step angle. The control accuracy of the AC servo motor is guaranteed by the rotary encoder at the back of the motor shaft.
    • Different low frequency
      Stepper motors are prone to low-frequency vibration at low speeds. The vibration frequency is related to the load condition and the performance of the drive. It is generally considered that the vibration frequency is half of the no-load take-off frequency of the motor. The AC servo motor runs very smoothly, and there is no vibration even at low speeds.
    • Different moment frequency
      The output torque of the stepper motor decreases with the increase of the speed, and the maximum working speed is generally between 300 and 600 rpm. The AC servo motor has a constant torque output, that is, it can output a rated torque within its rated speed, and a constant power output above the rated speed.
    • Different operating performance
      The control of the stepper motor is an open loop control, and the AC servo drive system is a closed loop control. The driver can directly sample the feedback signal of the motor encoder. The position loop and the speed loop are formed internally. Generally, the stepping motor will not lose steps or overshoot. The phenomenon of rushing.
    • Different speed response performance
      It takes 200 to 400 milliseconds for a stepper motor to accelerate from a standstill to a working speed. The AC servo system can accelerate from a standstill to its rated speed of 3000 rpm in just a few milliseconds, and can be used in control situations that require fast start and stop.

    For my 3D printer
    I needed a new nema 17 stepper motor for my 3D printer. It was skipping and erratic in Y axis movement. Many prints later, I am very happy with performance. All working as new.

    Great Nema 17 stepper motor and worth the money.
    This is a great Nema 17 stepper motor and worth the money. It was exactly as description. After attaching and wiring it up, it has worked flawlessly with very little heat. When I need more, I will buy from here again.

    Worked perfectly. Great products and fast shipping.
    I’m using three of these Nema 17 stepper motors, and I am both surprised and pleased at how well they run my CNC router. So far they work great, have never stalled or lost steps. Very happy with this purchase.

    It was an excellent purchase.
    I love this Nema 17 stepper motor. Packaging was quite adequate and the stepper motor arrived in great condition. I used it to replace my old one on 3D printer. It was a drop in replacement with no modifications to the printer at all. It was an excellent purchase.
