    Tips: Advantages and disadvantages of stepper motor

    A. Advantages

    1. The rotational angle of motor is in direct proportion to number of pulses.
    2. The torque is the largest when the motor stops rotating (when winding is excited).
    3. As the precision of each step is 3% to 5% and the error at one step will not be accumulated to the next one, so there is good position accuracy and repeatability of motion.
    4. Excellent start and stop and inversion response.
    5. Without electric brush, the reliability is high. Therefore, the service life of motor only depends on that of bearing.
    6. The response of motor is determined by the digital input pulse, so open-loop control can be adopted. As a result, the structure of the motor can be simple and the cost can be controlled.
    7. Synchronous rotation at extremely low velocity by only directly connecting the load to the spindle of motor.
    8. For the velocity is in direct proportion to the pulse frequency, there is wide range of rotational velocity.

    B. Disadvantages

    1. If not controlled properly, the resonance can be easily caused.
    2. Hard to rotate at high rotational velocity.
    3. Hard to obtain large torque.
    4. No advantage over volume and weight and low utilization ratio of energy resources.
    Existing reviews of Nema 23 2-phase Stepper Motor, 2A, 1.8 degree, 4 wires
    Good stepper motor.
    I bought this Nema 23 stepper motor for an arduino project. I can tell run smooth. Good  stepper motor.
