Stepper motors are electromechanical devices that provide precise rotational control by dividing a full rotation into equal steps. They employ a gear-shaped rotor and electromagnets, which, when energized in sequence, produce magnetic fields that interact with the rotor’s teeth to move in discrete steps. Widely used in robotics, CNC machines, 3D printers, and automation systems, stepper motors offer high torque at low speeds, excellent repeatability, and accurate positioning without a feedback system.
