8cm Mini Wind Turbine Propeller Blade for Mini DC Motor-Yellow

This compact 80 mm (8 cm) wind turbine propeller is designed for renewable energy demonstrations, small generator builds, and STEM education. Its lightweight, durable construction enables smooth rotation and reliable startup even at low wind speeds, making it ideal for hobbyists, makers, and electronics engineers working with mini DC motors, prototypes, and microcontroller-based experiments (e.g., Arduino, Raspberry Pi).

✅ Key Features

• 80 mm diameter with a 3-blade design for balanced airflow and efficient rotation.
• Lightweight, low-friction build for easy startup in gentle breezes.
• ~2 mm center hole sized for common micro DC motor shafts and toy motors.
• Compact form factor for classroom rigs, benchtop experiments, and microcontroller-based data logging.
• Cost-effective, robust component for STEM kits, makerspaces, and rapid prototyping.

🔎 Technical Specifications

• Diameter: 80 mm (8 cm)
• Material: Durable plastic
• Color: Yellow (stock may vary: typically red, blue, or black)
• Center Hole Diameter: Approximately 2 mm
• Weight: ~5 grams
• Number of Blades: 3-blade design
• Compatibility: Mini DC motors, toy motors, small generators

🔧 Compatibility & Integration

Pairs seamlessly with mini DC motors commonly used in educational electronics components and DIY kits. For generator experiments, the motor can act as a source to be rectified and measured by Arduino or Raspberry Pi data acquisition setups (via suitable modules such as a bridge rectifier and measurement interface). Performance depends on motor shaft friction and electrical load voltage characteristics.

• Recommended shaft size: ~2 mm. Use an adapter sleeve or adhesive if your shaft differs.
• For energy conversion projects, consider low-loss rectification (e.g., Schottky diodes) and appropriate load resistors or regulators.
• Not a powered fan by itself; requires a compatible motor (not included).

🧪 Applications

• Mini wind turbine systems
• Hobby and STEM educational projects
• Small generator systems
• Mini fans powered by DC motors
• Energy conversion experiments and science fairs
• Experimental prototypes for electricity generation
