How to Make your Own Fan

Making an electrical fan can be a relatively simple process when it is approached systematically. To complete the process one will need to get an electric motor and a fashioned air-screw which will drive the air away from the motor. This is a description of the basics of how to build an electric fan.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Wiring
• Wood Work tools

1. Most actual commercial fans are made of plastic or a more durable product but since plastic can not be readily made in the home, then a wooden air screw will have to suffice.

2. Get an electric motor. Usually a small electric motor which will run on mains power will do. Mount the motor onto a firm base so that the spindle can spin freely with the fan assembly once it is attached. For instance if the fan you make is a foot in diameter then you will need to mount the motor at least a foot from the ground.

3. Using a saw cut an air-screw to mount on the spindle, measuring, as above one foot in radius or two feet in length. Drill a hole in the centre point large enough to fit onto the spindle of the rotor on the electric motor. Shape the air-screw opposite to a propeller with a blade so that it will push the air in a forward direction when it spins. Smooth the air-screw with sandpaper and paint or polish it.

4. Attach the air-screw to the spindle of the rotor and ensure that it is secured and will not slip once the motor is on. Use a switching mechanism to regulate the power available to the motor and mount this between the motor and the mains power supply. This in turn should be mounted onto the motor assembly. Connect the power cord to a mains outlet and the motor will spin the air-screw, or fan. The switching mechanism will give you a variety or speeds for your fan.
