How a Small Wind Turbine Works

How a Small Wind Turbine Works

Okay, let's describe how a small wind turbine works in simple terms.

You can think of it as a "wind energy harvester." The process works as follows:

1. Capturing the Power of the Wind

Wind blows over the three blades of the generator. Due to their unique shape, the wind pushes them to start spinning, just like the wind in a windmill.

2. Conversion and Acceleration

The spinning blades drive a main shaft. Inside, a speed increaser (like a car's gearbox) converts the slow rotation into very fast rotation, enabling efficient power generation.

3. Core Power Generation

The high-speed rotation of the main shaft drives the core component of the generator—a set of magnets located within a copper coil—to rapidly rotate. Based on the basic principle of "magnetic induction of electricity," this process generates an electric current within the coil.

4. Processing and Storage

The newly generated current is unstable and needs to be "processed" by a controller to convert it into stable electrical energy. This electricity is then transferred to batteries for storage and use when needed. A clever design:

The tail fin on top of the generator acts like a weather vane, automatically aligning the blades with the wind, ensuring maximum utilization of wind energy.

In a nutshell: The wind rotates the blades, rotating them with magnets that wind around coils, generating electricity. This energy is stored and used when needed.
