Product Description
The 3-Blade Fan for 555 DC Motor is a lightweight, high-velocity propeller specifically molded to fit the 3.17mm output shaft of RS-555 series motors. Designed for maximum air displacement with minimal rotational drag, this fan is an essential component for DIY portable fans, localized cooling systems, and science fair projects. The aerodynamic curvature of the three blades is optimized to provide a concentrated stream of air, making it effective for cooling electronic components or creating small-scale wind tunnels. Its rigid plastic construction ensures that the blades maintain their shape even at the high RPMs typically generated by 12V-24V DC motors.
Key Features
Precision Press-Fit: Engineered with a center hub designed to grip the standard 3.17mm knurled or smooth shafts of 500-series motors without needing set screws.
Balanced Aerodynamics: The three-blade design offers a superior balance between torque requirement and airflow volume, preventing the motor from over-straining.
Impact Resistant Material: Manufactured from high-grade plastic that resists cracking if the fan accidentally contacts an object while spinning.
Universal Application: Ideal for custom cooling rigs, vacuum cleaner prototypes, or as a replacement blade for battery-operated handheld fans.
Low Noise Profile: The smooth surface finish and blade geometry help reduce the "whirring" noise caused by air turbulence at high speeds.
