8cm Mini Wind Turbine Propeller Blade for Mini DC Motor-Pink
This compact 8 cm diameter wind turbine propeller is designed for renewable energy experiments, small generator builds, and hands-on STEM learning. Its lightweight, low-inertia 3-blade rotor spins easily at low wind speeds, making it ideal for use with mini DC motors and educational demos involving voltage generation and energy conversion.
⚙️ Features & Benefits
- Low-friction, lightweight design (~5 g) enables rotation in gentle airflow
- Easy push-fit mounting on 2 mm motor shafts for quick prototyping
- Education-ready for STEM and science fair projects focused on electricity generation
- Compact 80 mm form factor suits desktop experiments and small enclosures
- Durable plastic construction for reliable classroom or lab use
- Affordable and versatile for hobbyists, makers, and electronics engineers

🧪 Typical Applications
- Mini wind turbine and small generator systems
- Hobby builds and STEM educational projects
- Mini fans powered by DC motors
- Energy conversion experiments and science fairs
- Experimental prototypes for electricity generation
🔌 Compatibility & Integration
Ideal for pairing with small DC motors (e.g., common 130/140-size toy motors). When driven by wind, the motor acts as a generator; you can measure the generated voltage using a multimeter or feed it into a microcontroller system such as Arduino or Raspberry Pi (via suitable electronics components and modules like rectifiers, capacitors, and ADC interfaces). This makes it a great accessory for learning about energy harvesting, load effects, and power conditioning.
📝 Notes & Tips
- Ensure your motor shaft is 2 mm for a proper friction fit. If needed, secure with a small amount of non-permanent adhesive.
- For generator experiments, consider adding a diode bridge and smoothing capacitor before measuring with an ADC or logging module.
- Operate in safe airflow conditions and avoid overspeeding the motor or propeller.
