Description
The 3V 6V 12V 24V 35V PWM DC Motor Speed Regulator is a Mini Style DC Motor Speed Regulator that controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM) signals. Designed for precision micro-motion tasks, it offers high-efficiency speed control for small DC actuators across diverse electronic, laboratory, and automated systems.
Important Precautions & Operating Guidelines
- DC Input Only: The governor input must be DC power. Never connect it directly to AC mains power (e.g., household 220V AC), as this will instantly burn out the circuit.
- Polarity Warning: Ensure correct positive and negative terminal connections for the DC power supply to prevent permanent damage to the regulator.
- Direction Adjustment: If the motor spins opposite to your expected direction, simply swap the motor wire sequence to reverse rotation.
- Speed Regulation: Rotate the onboard potentiometer knob to alter the output duty cycle and dynamically adjust motor RPM.
Key Features
- Operating Voltage: Wide input range covering DC 4.5V to 35V (compatible with 3V, 6V, 12V, 24V, and 35V nominal rails).
- Output Current & Power: Delivers 0 to 5A continuous output current with up to 70W maximum power handling.
- PWM Performance: Fine-tuned 1% to 100% duty cycle range operating at a stable 20kHz frequency.
- Ultra-Low Quiescent Current: Consumes only 7µA during standby mode for high energy efficiency.
- Miniaturized Dimensions: Compact physical layout measuring just 30mm × 26mm × 14mm (excluding potentiometer handle).
Benefits
- Micro-Enclosure Compatibility: Mini design allows seamless integration into compact handheld equipment and tight control panels.
- Acoustic Noise Reduction: 20kHz high-frequency PWM switching minimizes audible motor whining during operation.
- Reliable Power Management: Excellent low-drain idle characteristics protect battery-powered instrumentation setups.
Applications
- Small DC Hobby & Model Projects: Perfect for controlling miniature DC motors in model cars, boats, planes, and custom DIY maker creations.
- Cooling & Ventilation Systems: Ideal for regulating the speed of small DC exhaust fans, computer chassis cooling fans, and miniature air blowers to balance airflow and noise.
- Laboratory Stirrers & Mixers: Provides precise low-voltage speed adjustment for DIY magnetic stirrers, chemical mixing rigs, and small laboratory testing apparatus.
- Miniature Pumps & Dispensers: Smooth RPM control for small peristaltic pumps, liquid dispensers, and water circulation modules in automated plant watering systems.
- Custom Automated Jigs & Displays: Excellent for driving small motorized display turntables, camera sliders, and lightweight linear actuators in prototyping builds.
