Windmill Model – Small
Product Code : SCL-AM-11220
Quick answer: The Windmill Model - Small is a compact tabletop teaching model whose blades turn when air flows past them, from natural wind or a classroom fan. It is used to show how wind energy becomes mechanical motion in renewable energy and STEM lessons. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the model is used in teaching
Moving air carries kinetic energy. When wind strikes the angled blades of a windmill it pushes them round, and part of that energy becomes rotational energy of the rotor. In a modern wind turbine the rotor shaft drives a generator; in a traditional windmill it drove a pump or millstones.
The power available in the wind is P = 1/2 rho A v^3, where rho is the density of air, A the area swept by the blades and v the wind speed. Because power depends on the cube of wind speed, a modest increase in airflow makes a large difference, and students can see the rotor speed up as the fan is turned up or moved closer.
- Stand the model on a flat surface where the blades can turn freely.
- Check by hand that the rotor spins without catching.
- Direct natural wind or a classroom fan at the blades and observe the rotation.
- Change the fan speed or distance and compare how fast the blades turn.
- Discuss how wind farms convert the same motion into electricity.
