Wind Turbine Generator

Blades drive a small generator to light an LED, modelling clean wind power.

The build

Step 01

Make blades

Cut and angle blades on a hub.

Step 02

Mount the generator

Fix the hub to the motor shaft.

Step 03

Wire output

Connect to an LED or meter.

Step 04

Face the fan

Aim a fan and read the output.

Working Principle

Wind spins the angled blades, turning the motor as a generator that induces a voltage — mechanical energy becoming electrical.

The science behind it

A closer look

Blade count and pitch set how much wind energy is captured; the same induction as power-station generators applies.

Variables to test

  • 1 Test 2 vs 3 vs 4 blades for output.
  • 2 Change blade angle — find the best pitch.
