Learn How to Make a Wind Generator
A wind generator has several parts. To construct one, first know what you need and how to put it all together. Here are a few helpful hints for making one of your own.
Wind Generator Components
A wind generator looks sleek and tidy on the side of the road. It didn’t start out that way. It contains a few component parts:
• Rotor blades
• Generator
• Shaft
• Tower
• Wiring

If you are going to build a wind generator, what type will it be? On or off the grid, you can use a battery or connect the wind generator directly into the house. For that you will also need:
• Deep cycle battery (if using electricity storage)
• Controller ( to keep track of electricity in the system)
• Inverter (to change current types to fit household needs)
Rotor Blades
Rotor blades are made from PVC or ABS pipe. The blades will be fairly large so find piping that is 8 to 12 inches in diameter. The instructions will guide you on cutting the blades to the precise size for your tower; the blades will fit on a hub like the blades on an airplane propeller.
Generator
Once they are bolted on, the entire rotor head is attached to the generator. It is a DC motor secured in housing. From the motor, the wiring connects to the rest of the system. Look for a motor with low RPMs and a high voltage and current output. A decent motor can be found on eBay. Check the specs to see if they match what you are looking for. A tail assembly is added to the back of the motor for balance.
Shaft and Tower
The rotor head is attached to a shaft that has been fixed on the top of the tower. This works best with a tower that narrows at the top for the wooden shaft to be added. If the tower is the same diameter throughout, it will have to be cut for the shaft to fit over the top. The shaft allows the rotor to spin on the tower and catch the winds in any direction.
Towers stand several feet in the air. How high your tower stands is up to you and your system needs. The tower will be cemented in place once the entire structure is level.

Once the tower is constructed and wired, the wiring is sent to a controller. The controller is then wired to a battery to store excess electricity. If no battery is used, the electricity is wired to an inverter that converts electricity to usable current that is passed on to the household wiring.
