A stepper motor is a type of electric motor that divides a full rotation into a series of equal steps. This allows for precise control of position and speed, making them ideal for applications like 3D printers and CNC machines. Unlike traditional motors, which rotate continuously, stepper motors move in fixed increments, enabling accurate control over movement. Stepper motors operate by energizing coils in a specific sequence, causing the motor to rotate in small, precise steps. They are commonly used in robotics, automation, and other fields where precise positioning is crucial. Their ability to maintain position without needing feedback systems makes them popular in various applications.
