Mini wind turbine
1. Definition
A mini wind turbine is a simple device that converts wind energy into electrical energy.
2. Principle
It works on the principle that moving air turns the turbine blades, causing a small motor/generator to
rotate and produce electricity.
3. Main Parts
Turbine blades
Small DC motor
Connecting wires
LED bulb
Stand/support
Small hub to hold the blades
4. How It Works
Wind blows against the blades.
The blades rotate.
The rotation turns the shaft of the motor.
The motor acts as a generator and produces electrical energy.
The electricity can light an LED.
5. Energy Transformation
Wind energy → Mechanical energy → Electrical energy → Light energy
6. Advantages
Uses renewable energy.
Does not produce smoke or harmful gases during operation.
Can be made using simple materials.
Useful for demonstrating how wind power works.
7. Limitations
It depends on the availability of wind.
A small model produces only a small amount of electricity.
The blades and motor need to be properly positioned for good results.
