Make Small wind turbine at your home. You can see hundreds of make small wind turbine videos describing how to make small wind turbine at home easily. But many of them are not very helpful. Many of them do not offer a complete guide to make small wind turbine that works as a real one.
People are not satisfied, which can be understood from their comments. They are searching google again, again and again for more Make Small wind turbine videos. So I decided to build a small wind turbine and upload the making video on youtube. I went to town and bought necessary tools and parts from a hardware shop. Then I asked my friend to shoot video using my Smartphone.

Let’s watch How to Make small Wind Turbine

Done?? How is it?

Later I realized a video is not enough to educate all kinds of people those who are willing to make small Wind turbine. In this post you can read each and every step I followed to make a small wind turbine. Don’t forget to comment your opinion and share it with your friends.

How to Make Small Wind Turbine

Main Segments

  • Turbine Propeller
  • Turbine dynamo casing
  • Turbine Base
  • Turbine tail

Wind turbine propeller

Make Small wind turbine propeller[/caption] \

A wind turbine propeller converts wind energy n to rotational mechanical energy. It is the most important part of a wind turbine.Let’s learn how to make turbine propeller.

  • Buy a 10 inch PVC Pipe (3inch in diameter)
  • equally divide the edge perimeter
  • Cut the pipe into blades as shown in video- watch video
  • Make holes as shown in the picture on anything round in shape with 2.5 inches.
  • Then screw 3 blades to it using cycle screws.

Keep in mind

  1. The weight of each blade should be equal.
  2. Each blade should be positioned on the plate at equal distances.

Wind turbine Dynamo Casing

Make Small Wind turbine Casing[/caption]

Dynamo casing holds both Dynamo and Autorotation Mechanism. A dynamo is used to convert mechanical energy or rotational energy generated by wind turbine propeller into electrical energy. If a dynamo converts mechanical energy into Alternating current it is known as Alternators. Different types of generators are available in the market.

  • wire
  • A piece of pen
  • PVC Fitting T
  • Buy 2 bearings
  • Buy a dynamo 3V
  • Connect the dynamo to the PVC fitting.
  • Connect the two bearings to a common axis. A piece of a pen can be used as the axis.
  • connect one bearing to the PVC T

The bearing setup is an autorotation mechanism (yaw mechanism). It helps the wind turbine to face the wind. When the direction of the wind changes from east to west, the tail-autorotation mechanism will automatically adjust the propeller to directly face the wind to utilize maximum wind energy.

Make small Wind turbine Base

The turbine base and the post holds the propeller, dynamo, tail, and autorotation mechanism. It is very easy to make the turbine base. Buy some PVC fittings.

  1. Elbow – 4
  2. PVC T – 3
  3. PVC pipe pieces

Connect these fittings as shown in the figure.

Make Small Wind turbine tail

Small Wind Turbine tail[/caption] Most of the DIY  wind turbine videos on youtube doesn’t have a tail- autorotation mechanism. Without a tail-autorotation mechanism, a Small wind turbine is not complete. What is the purpose of a tail? The tail auto rotation mechanism will help the propeller to change the direction to face the wind. Th tail will force the propeller to face the wind even at higher wind speeds.

  1. cut GI sheet
  2. PVC Pipe, reducer

The Wind turbine is ready. Check its Working

  • Place the wind turbine in front of a fan
  • connect a multimeter to the output wires of the dynamo.

Yes, Multimeter needle is indicating a current flow through it. If you are using an efficient Dynamo, you can use this dynamo to charge your 3 v rechargeable battery. Besides, You can build a larger wind turbine than this to charge your smartphone too. Watch this video  make small wind turbine at home Hope you have enjoyed this DIY article. You can point out any fault from me. I welcome your comments. If you have any doubts about this project, ask me. But don’t forget to share it with your friends.

      Hi, I’m trying to get hold of the bearing in the UK & no one seems to know what ones they are. Could you send me a link from the UK, that do those bearings please? I have everything else, apart from the bearings and the AC. Thanks so much for your help.

What size of dynamo do I need to charge my smartphone

Kiki van Caspel · November 6, 2016 at 4:35 am

Hi! I’m trying to make a small windturbine, but instead of using a propellor like yours I’m using toy windmills like these:
I’m trying to power a 3V motor with it, but I’m struggling to get enough voltage. I was wondering how much voltage this one is generating and if you have any tips for me?

    Aromal Karuvath · November 6, 2016 at 1:11 pm

    It’s difficult to get 3 volts by using a propeller like this. The voltage generated is directly proportional to the Total area of the circle generated by the propeller.

    1. Increase the area
    2. Buy a high performance dynamo instead of using DC Motor

Hello, I’m building a wind turbine for my school project and I am thankful for your video it was very helpful to me. But I just want to know where you got the bearing from and what is the size/name of the bearing exactly?

    Aromal Karuvath · December 11, 2016 at 3:55 am

    Its 1.25 inch dia ball bearing. You can buy it from any hardware shop. Or buy from amazon. It costs around 0.5$

Blesson · December 29, 2016 at 3:45 pm

Hi iam Blesson from chennai. Iam interested to make a wind mill turbine. See of you video. And I have doubt of it where we will get generator motor pls reply me my mobile no:-9003299055

    Aromal Karuvath · December 30, 2016 at 12:53 am

    You can buy wind turbine dynamo from amazon. It’ll cost more than 10$. If you can’t afford this, try DC motor instead. It’ll work. Regards. Let me know once you complete your project.

Blesson · December 31, 2016 at 1:15 am

Hi I searched in amazon but I didn’t got it. What name of that and you can send me the link of that in my what app number:- 9003299055.

Rako · January 11, 2017 at 11:30 pm

Hi, at the end of the video you said if you want to charge a phone you need to built a bigger wind turbine. How is that done, or can we make two of the one you have showed and connect both of them together so we have double the power.

Sagar Aldar · February 1, 2018 at 9:54 am

Hello sir this is amazing project but I want to know that I’m using gear motor which has 12v and 1000rpm speed and I’m also making that propeller the u make so how much current will generate can it charge the mobile if yes then how any formula for calculate that how much current is generated from my motor and etc

vinod pachbhai · February 2, 2018 at 11:25 am

Sir I want to charge 10ah 12v battery so suggest me specification about dynamo and size of blade
