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 the motor's position, making it ideal for applications that require accurate movement, such as in 3D printers and CNC machines. Stepper motors operate by energizing coils in a specific sequence, causing the motor to move in discrete steps. These motors are commonly used in robotics and automation due to their reliability and ease of control. Unlike traditional motors, which rotate continuously, stepper motors can hold their position when not in motion, providing stability in applications like robotic arms and camera gimbals.
