    Tips: The difference in overload capacity between stepper motor and AC servo motor

    Stepper motors generally do not have overload capacity. When using, you must ensure that the load is within the required range. Once overload occurs, normal operation will be affected.

    But the AC servo motor is just the opposite. It has a relatively strong overload capacity, and can be more complicated in the application. The load exceeds the rated value and can still function normally, and it will not cause adverse effects because the load is not within the required range.

    For my CNC machine
    I like this nema 23 stepper motor very much. I am using them in my new CNC machine. It's been in use for three months now. It's great that a small nema 23 stepper motor can do so much.
