Stepper motors are a type of electric motor that move in precise steps, allowing for accurate control of position and speed. Unlike traditional motors that rotate continuously, stepper motors divide a full rotation into a series of discrete steps, making them ideal for applications requiring precise movement, such as in 3D printers and robotics. These motors operate by energizing coils in a specific sequence, which creates magnetic fields that pull the rotor into alignment with the fields. This step-by-step movement enables stepper motors to maintain their position without needing feedback systems, making them efficient for tasks like CNC machining and automated systems.
