Product Code : SCL-SK-12140
Windmill Working Model (3-Blade) (SKU SCL-SK-12140) is a renewable-energy teaching model in which moving air turns three blades, showing how wind energy becomes mechanical and, where a generator is fitted, electrical output. It serves school science labs, college physics rooms, environmental science classes and exhibitions. Made at the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, the model is supplied straight to schools, colleges, tender contractors and distributors.
Specifications
The model has a three-blade rotor that turns freely in a gentle airflow from a fan or natural wind, so students can see blade speed respond to the air. Blade diameter and material, generator output, base design and any load accessory are confirmed on the quotation for the version offered.

Applications and Experiments for the Windmill Working Model
Students direct airflow at the rotor, watch how blade speed changes with the air, and observe a connected LED or meter respond where one is supplied. The model supports wind-energy and energy-conversion topics in middle and secondary school science, environmental studies and STEM projects on clean power.
- School science: wind as a renewable source of energy and how a windmill works.
- Energy conversion from moving air to rotation to electrical output.
- Comparing blade speed under different airflow strengths and directions.
- STEM projects and science exhibitions on wind power.
Standard Scope of Supply
The Windmill Working Model (3-Blade) is supplied as a single model as described above, with its three-blade rotor. Whether a generator, LED, meter, switch or wires come with it depends on the configuration quoted, and the quotation lists each part so there is no doubt about contents.
Packing, MOQ and Lead Time
One model for a demonstration or a quantity for class groups can be quoted. The quotation gives packing, delivery time and price for your number, and STEM science kits in India such as solar or water-power models can be included so a whole energy unit is ordered at once.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
Does the windmill model generate electricity?
It can show generator output where a dynamo and load are supplied with the version you order. The quotation confirms whether a generator is fitted and states its output.
How many blades does the model have?
Three. The three-blade rotor turns in airflow from a fan or natural wind, letting students compare blade speed as the strength and direction of the air change.
Is Science Lab Supplies the manufacturer of this model?
Yes. The company is a science kit manufacturer in India and makes the windmill in its Saha, Ambala factory in India; quotations are issued by the factory itself, not by an agent.
How should students use it safely?
Under teacher supervision, with a gentle airflow only. Keep fingers, hair and loose clothing away from the blades, do not use cracked blades, and never connect the model to mains electricity.
