Must the stepper motor be driven?

Not necessarily, but if you do not have a controller or device (such as a PLC, etc.) that sends signals (usually called pulses) to the motor, then you must drive.

Example of stepper motor & driver combination

Why must the stepper motor drive or related drive parts? This has to learn the working principle of the stepper motor: the stepper motor is a motor that converts the electrical pulse signal into the corresponding angular displacement or linear displacement, each input pulse signal, the rotor rotates an Angle or further forward, the output angular displacement or linear displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. So the concession to the motor must have an electrical pulse signal, and the controller and PLC is to give this electrical pulse signal to make the motor turn, but most of us use the matching stepper motor driver to achieve, which has input and output points, and some can also be subdivided and programmed, the control of the stepper motor is more simple, convenient and easy to operate.
