The 28BYJ-48 12V 4-Phase Stepper Motor is a small electric motor designed for precise control of motion. It operates using a 4-phase stepping sequence that allows for accurate positioning and smooth movement. With its compact size and low power consumption, this motor is ideal for use in a wide range of applications, including robotics, automation, and precision instrumentation.

At the heart of the 28BYJ-48 4-Phase Stepper Motor is a series of electromagnets that are arranged in a precise pattern. By applying electrical signals to these magnets in a specific sequence, the motor rotates in small, incremental steps. The motor’s step angle is 5.625 degrees, which means that it takes 64 steps to complete a full rotation.

The 28BYJ-48 4-Phase Stepper Motor has a maximum operating voltage of 12 volts DC and a current rating of 200mA. It is also equipped with a gear reduction system that allows for increased torque and improved performance at low speeds. The motor’s output shaft is 5mm in diameter and has a flat edge for easy attachment to other components.
