Students, teachers, and hobbyists love using these turbines to learn and teach about wind energy science and technology. Wind Turbines harness the power of the wind to small wind turbine pdf electricity.
Today turbine production is rapidly expanding all over the United States and the world. This instructable will help you learn about wind turbines through a hands-on project. Before we get started, run your mouse over the highlighted boxes on the picture of the turbine. This will help you understand the basic anatomy of a wind turbine. You will need a fan or a wind source to make your wind turbine run. First, drill a hole at the bottom of one PVC T. 6″ PVC pipe sections, construct the two sides of the PVC turbine base.
Make sure in this step to use the PVC Ts that do not have a hole drilled in them. To make them fit snug, tap them together with a hammer or bang them on the floor once assembled. Next, connect the two sides of the base using the PVC T with the hole. The hole will allow you to snake out the wires from the DC motor. First, attach the wires to the leads of the motor. We tie them together and shrink wrap them too.
Wrap a piece of duct tape around the outside of the motor. This will help the motor fit securely into the PVC coupler. Arrange the pieces as they look below. Push them together to form a solid piece.
On a large wind turbine this is called a nacelle. It holds the generator, gear boxes, and other equipment. Insert the wires attached to the DC motor through the nacelle. They should come out of the 90 Degree PVC fitting. The motor will rest in the coupler. Insert the motor into the coupler. Since the motor is sometimes pushed frequently, it must be TIGHT!
You can also glue the motor in to make it secure. You might also tape the wires down inside the pipe to prevent breakage if someone yanked on the wires. Make sure the motor is straight and not too far in. If it looks cockeyed, straighten it out. Otherwise it will cause your hub and blades to wobble while spinning. Once the motor is secured, attach the hub. Press the hub onto the drive shaft.
Snake the motor wires down the tower and through the hole in the PVC T at the base of the wind turbine. It is sometimes helpful to place a piece of tape over the wires as they come out of the hole to prevent the wires from being broken at the motor if yanked too roughly. Attach the nacelle to the top of the tower. Insert the bottom of the PVC tower into the T at the center of the turbine base. Assure that the PVC pipe is seated tightly into the fittings by tapping together with a hammer or by banging on the floor. Do not use any glue so that you can take it apart and store it for next year! Attach alligator clips to the wires coming out of the turbine to help hook up your turbine to a multimeter!
Never make blades out of metal or any sharp edged material because they could cause injury during testing. Tape or hot glue them to the dowels. Students have made blades out of styrofoam bowls, pie pans, and paper and plastic cups. Anything you find around the house or classroom can be made into blades!
Before testing check that the blades are securely attached to the dowel. If not secured properly, they may detach or deform as you test your turbine in high winds. We recommend using a combination of tape and hot or regular glue. Insert the dowels into holes on the crimping hub. It is important to tighten the hub when inserting the blades so that they do not come out at high speed. How close is the root of your blade to the hub?
