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 suits school science labs, college physics rooms, environmental science classes and exhibitions. Science Lab Supplies is the manufacturer, building the model at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, for direct supply to schools, colleges, tender contractors and distributors.
Specifications
All the specifications of the three-blade windmill are given in the table. In short, its three-blade rotor turns in airflow from a fan or natural wind, so students can compare blade speed and output response, and output depends on blade design, airflow, generator type and load rating.

Applications and Experiments for the Windmill Working Model
Students can 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, explained through the coils and galvanometer of the Apparatus for Studying the Production of Electricity by Induction.
- Comparing blade speed under different airflow strengths and directions.
- Contrasting a generator with a miniature Electric Motor (1.5–4.5 V DC), which turns electricity into rotation.
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 are packed with it depends on the configuration quoted, and the quotation lists each part so the contents are clear in advance.
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). Wind-energy enquiries are answered from the contact page, longer lists can go through the enquiry cart, and the lab tender page covers institutional tenders.
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, so you know what the class will see.
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. Each three-blade windmill is made in the company’s Saha, Ambala factory in India, and quotations are issued by that factory itself rather than by an agent or distributor.
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.
