RF-370CB Carbon Brush Mini DC Motor 6V 0.45W 5500RPM Low Noise Micro Air Pump Motor for Breast Pump Applications

RF-370CB 6V Carbon Brush Mini DC Motor for Micro Pump & Medical Applications

The RF-370CB 6V Mini DC Motor is purpose-engineered for precision-driven applications including micro air pumps, AC damper actuators, robot vacuum cleaners, and medical-grade breast pumps. With its carbon brush construction, ultra-low noise operation under 35dB, and compact 24.4mm body diameter, this motor delivers the quiet, reliable performance that sensitive consumer and medical devices demand.

Key Features

• Ultra-Low Noise Design: Precision-balanced rotor and optimized brush-commutator interface keep noise under 35dB — critical for breast pumps and robot vacuum cleaners operating in quiet home environments.
• Carbon Brush Reliability: Metal graphite carbon brushes ensure stable electrical contact, minimal spark interference, and 1000+ hours of continuous service — ideal for medical devices requiring consistent performance.
• Ideal for Micro Air Pumps: Smooth 5500RPM output at only 0.45W provides the perfect balance of airflow generation and energy efficiency for portable micro air pump systems.
• AC Damper Actuator Ready: Compact size and reliable start-stop performance suit HVAC damper actuator mechanisms requiring precise angular positioning.
• Wide Voltage Tolerance: Functions reliably from 3V to 7.5V DC, accommodating battery discharge curves in cordless robot vacuums and portable breast pumps.

Target Applications

• Micro Air Pump: Portable air pumps, blood pressure monitors, massage devices, air sampling equipment
• AC Damper Actuator: HVAC zone control dampers, ventilation flap actuators, air mixing box motors
• Robot Vacuum Cleaner: Side brush drive, suction fan drive, dust bin mechanism
• Breast Pump: Electric breast pump vacuum motors, wearable pump modules
