Product Description This 3-blade plastic propeller is an essential component for DIY electronics, school science projects, and hobbyist RC builds. Specifically designed to fit the 2mm shafts of common small DC motors (like the 130 or 140 series), it provides a balance of high airflow and low rotational inertia. Molded in vibrant colors from impact-resistant plastic, these fans are perfect for building mini air-boats, table fans, wind-mill models, and solar-powered cooling experiments.

Key Features

Precision 2mm bore for a secure friction-fit on most toy motors.
Lightweight aerodynamic blades designed for high-speed rotation.
Smooth surface finish reduces air turbulence and noise.
Durable, flexible plastic that resists breaking during accidental impacts.
Available in multiple colors to suit different project aesthetics.

Technical Details

Shaft Fit: 2.0 mm (Hole is slightly undersized for a grip fit)
Total Diameter: ~56 mm
Hub Height: ~10 mm
Weight: Approx. 2g to 3g
Material Property: Non-toxic, recyclable plastic
RPM Range: Optimized for 2,000 – 15,000 RPM

Prototyping and Engineering Tips from Robogears

Installation: When pushing the fan onto a motor shaft, place the back of the motor on a hard surface to prevent the motor's back plate from popping off. Do not use glue; the friction fit is designed to be tight enough for high-speed use.
Airflow Direction: If the fan is blowing air in the wrong direction, simply reverse the two wires on your motor. DC motors change rotation based on polarity, and these blades are designed to push air regardless of which side is "front."
Battery Pairing: For best results with this fan size, use a 3V to 6V power source. A standard 9V battery works well for high speed, but ensure the motor is rated for that voltage to prevent overheating.
Safety: While the plastic is lightweight, keep fingers away from the blades when rotating at high speeds. For classroom projects, consider building a simple cardboard guard around the fan.
