How to Make an Electric Fan

Save

An electric fan is one of the simplest circuits that you can make. All it requires is a motor, a power supply and a fan blade.As long as you get the voltage and amperage right and there is nothing wrong with your motor, your electric fan should work for years without any trouble. Use a battery pack if you want to make a quick science project. Use a plug-in power supply for a more permanent fan.

Things You'll Need

  • Solder Soldering iron Electric motor Fan blade Power supply Super glue Insulating gloves
  • Buy fan blades and a motor. Make sure that the fan blades have a hole in them which is the same size as the electric motor. Alternately, you can buy a kit including a fan, electric motor, power supply and housing such as the one linked to below.

  • Get a power supply with the right voltage and amperage for the motor. For a small electric hand fan, a battery holder such as the one linked to below should do the job. Alternately, you can buy an electric adapter that plugs into the wall.

  • Test the motor. Touch the positive lead to the positive lead of the motor, and the negative to the negative. Switch on the power supply.

  • Put the electric fan blade on the motor. Simply push the shaft through the hole in the blade. Use a drop of super glue to secure it.

  • Hook the power supply to the motor. Solder the positive lead to the positive terminal and the negative lead to the negative terminal.

  • Switch the circuit on. Plug it in or put in the batteries, and turn the switch to "On" if your power supply has a switch. The fan should start turning immediately.

Tips & Warnings

  • Do not get a power supply that puts out more voltage than the motor is designed for. A power supply that puts out more amperage, however, is okay. To use the fan, glue the motor onto a base. Make sure that the fan is free to spin without banging against the base.
  • If you are using a wall-mounted power supply, wear rubber insulating gloves when you are testing out the circuit.
