The 3V / 6V / 12V / 24V / 35V 5A PWM DC Motor Speed Regulator is a compact and robust controller designed to provide precise and efficient speed control of small to medium DC motors using PWM (Pulse Width Modulation) technology. With a wide input voltage range from 3V to 35V DC, and a maximum current rating of 5A, this regulator is suitable for powering and controlling a wide variety of DC motors used in robotics, automation systems, DIY projects, fans, blowers, and other electromechanical assemblies.
The PWM control method allows for smooth, stepless speed adjustment without generating excessive heat, making it ideal for applications where precise speed regulation and efficiency are important. Unlike linear regulators, PWM delivers power efficiently by switching the supply on and off rapidly, ensuring minimal power wastage and stable motor performance.
This controller is perfect for hobbyists, makers, students, and engineers seeking to fine-tune motor speeds for robotics, automated wheels, conveyor belts, air blowers, pumps, small vehicles, and experimental setups. The module can be integrated easily into custom PCB layouts or DIY enclosures, and its intuitive control interface allows quick adjustment of motor speed using a potentiometer dial.
Compatible across a wide range of voltages, this PWM speed regulator simplifies power management while enhancing motor lifespan and operational smoothness.
