The wind turbine that we are working on, has been made up of:
1- Three Blades
2- Blade Holder
5- 3 Phase Brushless Generator
6- Converter Circuit
7- Switching and Inverter Circuit
8- Output Transformer
9- The Tail
How the wind turbine works
Wind’s kinetic energy causes the blades turn around the shaft of the gearbox. Then gearbox output shaft, turns the generator shaft faster and the electrical energy will be made inside of the generator.
The first step is converting the high voltage 3 phase output to a DC voltage source.
Then the DC voltage will be switched to a usable 50Hz 220VAC source. This wind turbine can charge a battery or plugged to the local electricity circuit. Also is suitable for windy places.
This turbine is a cheap and light weight. The blades turn in un-clockwise direction and the tail holds the blades in the angle of wind.
Here’s the process form the start to now:
1- The first prototype, we used belt-pulleys as the rpm multiplier, the generator and the blades were too weak and total output was about 20W@10m/s
2- Then we made some improvements in the blades and add a gearbox and the total output was about 300W@10m/s wind speed.
3- We made some improvements in the generator and could receive 1KW@10m/s wind speed.
We’re still working on the wind turbine. As soon as we reach to a stable 1KW output and test it enough, we will release the Calculations, Plans, Schematics and the DIY instructions on our online store.
