    Tips: Stepper motors must be equipped with motor drivers to work

    The permanent magnet stepper motor cannot be directly connected to the frequency AC or DC power supply like DC motor and AC motor. It must be equipped with a dedicated stepper motor driver to work. Because the stepper motor is composed of pulse generation control unit, power drive unit, protection unit and so on, the conventional application cannot be realized in terms of structure and principle.
    The drive unit of the stepper motor must be directly coupled with the stepper motor driver to ensure electromagnetic interference, so that the electronic circuit can be used to change the direct current into time-sharing supply, and the multiphase timing control current. That is, the stepper motor must have a driver to supply power.
