Windmill Working Model (3-Blade)

Product Code : SCL-SK-12140

The Windmill Working Model 3 Blade is a renewable-energy teaching apparatus used for demonstrating how moving air can rotate three blades and convert wind energy into mechanical or electrical output. It is suitable for schools, colleges, STEM labs, physics practical rooms, environmental science classes, science exhibitions and educational procurement buyers.

Product Description

The Windmill Working Model (3-Blade) from Science Lab Supplies is intended for classroom demonstrations of wind energy, blade rotation and energy conversion. The supplied product name confirms a three-blade windmill model, but the generator output, blade diameter, blade material, base design, load accessory and dimensions must be confirmed before final catalogue publication.

This model helps teachers explain wind power, rotor movement, mechanical energy, dynamo action, electricity generation and renewable-energy systems. Students can observe how airflow affects blade speed and how a connected load, such as an LED or meter, responds where such accessories are supplied.

Key Features

• Three-blade working model: supplied product name confirms a 3-blade windmill format.
• Wind-energy demonstration: shows how moving air can produce blade rotation.
• Energy-conversion learning: supports lessons on wind energy, mechanical motion and generator action.
• STEM project value: suitable for school exhibitions, renewable-energy activities and science demonstrations.
• Capacity not applicable: this is an energy model, not a liquid-volume product.
• Visible classroom operation: helps students compare airflow direction, blade speed and output response.
• Specification-dependent performance: output depends on blade design, airflow, generator type and load rating.

Technical Specifications

What's Included in the Kit

How to Use the Windmill Working Model (3-Blade)

1. Confirm the model configuration, safe airflow method and approved load before use.
2. Place the windmill model on a stable, dry and level surface.
3. Check that the three blades rotate freely without touching the tower or frame.
4. Connect the supplied load, such as an LED or meter, only as instructed.
5. Direct safe airflow toward the blade assembly using an approved fan or natural wind.
6. Observe blade rotation and any connected electrical output.
7. Record airflow condition, blade speed observation and load response.
8. Switch off airflow and disconnect loads before storage.

Safety note: Use under teacher supervision. Keep fingers, hair, loose clothing and wires away from rotating blades. Do not use high-speed air sources, overload the model, connect it to mains electricity or operate it with cracked blades.

Care & Maintenance

• Store the model dry and protected from dust, impact and moisture.
• Clean blades gently with a soft dry cloth.
• Do not bend blades, pull wires or force the shaft.
• Remove from use if blades crack, wiring loosens, the tower becomes unstable or rotation becomes jammed.
