Windmill Model Kit
Product Code : SCL-AM-11321
Quick answer: The Windmill Model Kit is a renewable energy demonstration model in which moving air acting on the blades turns a rotor, the working principle of a wind turbine. Teachers use it to explain wind power and energy conversion and to compare wind with solar and hydro sources. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the model is used in teaching
Each blade of a windmill is set at an angle to the oncoming air. Air striking the blade is deflected, and by Newton's third law the blade is pushed the opposite way; the part of that push acting around the axle makes the rotor turn. The faster the air moves, the greater the force on the blades and the faster the rotor spins.
No wind machine can capture all the kinetic energy of the air passing through it, because the air must keep moving to leave the blades. The theoretical maximum, known as the Betz limit, is 16/27, or about 59 per cent of the energy in the wind. This is a useful discussion point when students compare wind with solar and hydro power, including why wind output varies with the weather and why turbines are sited on high, open ground.
- Place the model securely on a flat, dry laboratory table.
- Check that the blades and rotor turn freely.
- Direct a steady airflow from a fan at the blades and observe the rotation.
- Vary the airflow and note the change in rotor speed, linking it to wind speed in real turbines.
Key features
- Visible model of how airflow produces rotational motion
- Introduces wind power as a renewable, alternative energy source
- Supports discussion of kinetic, mechanical and electrical energy in a wind turbine
- Easier to follow than diagrams alone in physics and STEM lessons
- Works alongside solar and hydro models for comparative renewable energy teaching

Frequently asked questions
What does the windmill model kit demonstrate?
It shows how moving air acting on angled blades makes a rotor turn, the principle by which wind turbines extract energy from the wind.
Why can a wind turbine not use all the energy in the wind?
The air must keep flowing away from the blades, so some kinetic energy always remains in it. The Betz limit puts the theoretical maximum at about 59 per cent.
