💡 Typical applications
- Mobile platforms and lightweight robots
- Micro-drones and small aircraft
- Miniature fans and pumps
- Arduino/ESP32 projects requiring a fast motor
- High-speed, low-torque mechanical devices
⚙️ Use and installation
- Power: connect +12 V to the positive terminal and GND to the negative terminal.
- Reverse the polarity to reverse the rotation direction.
- For PWM speed control, use a MOSFET driver rated for at least 2 A or an H-bridge such as the L298N or L293D.
- Mount through the M2 holes and leave 5–10 mm of clearance around the motor for ventilation.
- Solder a 0.1 µF capacitor across the terminals to reduce electrical interference.
🔩 Optional propeller
- Diameter: 75 mm, two blades
- Bore: 2 mm, mounts directly on the shaft
- Use: micro-drone propulsion or auxiliary fan
- Recommended speed: 8,000–12,000 rpm for effective airflow
This fast, adaptable motor is ready for small propulsion or ventilation projects when paired with a compatible 75 mm propeller.
