How To Turn A Box Fan Into A Wind Turbine?

Wind turbine with a box fan

Substitute a D/C generator motor for the A/C motor. Keep the box and fan blades. Connect the back of the motor to the charge controller and the battery with two fused wires (s).

Make a tail segment that attaches to the box fan for rotation (attach a 3′ section of 1-1/2″ PVC to one end of the box fan). Make something flat, like a 12″ by 12″ piece of lexan, for the tail section’s other end. Make a small pole mount (similar to a chair mount swivel base) that allows cables to flow through it and rotates 360 degrees. Place the unit in a region where wind tunneling is possible. Testing can be done on the ground.

Is it possible to turn a fan into a wind turbine?

On trash day, it’s not uncommon to see one or two ceiling fans flung about carelessly atop a pile of rubbish bags, ready to be carried off to the town landfill. It’s a waste to throw something like this out, so he decided to see what he could do with one. He was able to convert a ceiling fan into a wind turbine after a lot of hard effort (of sorts).

While some generators and motors can be used interchangeably by reversing the flow of power (motors as generators and vice versa), this is not the case with ceiling fans. These motors are induction motors, which do not have permanent magnets and hence cannot be employed as a generator as a cost-cutting approach. You can get around this disadvantage of induction motors by modifying them, such as rewiring parts of the windings and placing permanent magnets around them.

It’s worth noting that this isn’t the best technique to design a generator. The motor isn’t as efficient as one made with its own set of magnets, even after making all of the necessary alterations to get it operating. It’s not a fantastic time investment for a low-quality generator, despite all the effort that put into it. Even though the end result wasn’t a complete wind turbine, it’s fascinating to see the theory behind something like this work at all. Perhaps you can put an old ceiling fan to greater use if you have one laying around.

Is it possible to use a fan motor as a generator?

Because the fan is a bi-directional mechanism, it may convert wind energy directly into mechanical energy. To obtain electrical energy, modifications to the motor must be made in order to create a generator. These motors have a fairly simple design.

Is it possible to use a ceiling fan as a wind turbine?

The super typhoon Odette wreaked such havoc on Cebu and other portions of Visayas and Mindanao that residents have been without power for more than a week.

This Cebuana, on the other hand, shared a highly valuable power hack with individuals who do not have access to a generator. There are only three things you’ll need: wind, a ceiling fan/electric fan, and an extension cord.


  • When there are heavy gusts, put the ceiling fan or electric fan in front of them.
  • Connect it to your extension cord.
  • Allow the wind to take its course.
  • After that, connect your charger to your extension wire and charge your phone.
  • There’s no need to plug the extension cable in anyplace.

It is important to use operating ceiling fans rather than damaged ones for this to work. Wind turbines absorb kinetic energy from the wind by using blades.

Cebu’s people have always been resilient. We hope that this will work for you and that it will assist you in getting through this difficult time.

What is the best motor for a wind turbine?

Brushed DC motors are primarily used in home-made wind turbines. The power in a brushed DC motor comes from a commutator rotating the brushed motor’s electromagnets. A properly brushed DC motor can achieve high efficiency levels of up to 70%. An axle constructed of hardened stainless steel, a stack of laminations, wire, and brushes make up a high-quality brushed motor. One of the benefits of using a brushed DC motor is that it does not require any gearing while still charging a battery with voltages produced by light wind. Brushless DC motors are also easily accessible.

Is it true that stronger magnets generate more electricity?

Increasing the magnet’s strength will result in a stronger magnetic force on the wire and, as a result, more voltage (and therefore current). However, this is not always simple. It helps to have a larger magnet, but you can also create better magnets. Better magnets can be manufactured with more expensive alloys or manufacturing procedures, and scientists are working on thousands of ways to improve them. This is true whether you’re making direct current or alternating current.

To power a home, how big of a wind turbine do you need?

Small wind turbines for home usage typically range in size from 400 watts to 20 kilowatts, depending on how much electricity you need to create.

Each year, a typical home consumes roughly 10,649 kilowatt-hours of electricity (about 877 kilowatt-hours per month). A wind turbine rated in the range of 515 kilowatts would be necessary to produce a meaningful contribution to this demand, depending on the typical wind speed in the area. In a location with a yearly average wind speed of 14 miles per hour (6.26 meters per second), a 1.5-kilowatt wind turbine will cover the needs of a home consuming 300 kilowatt-hours per month.

A competent installation can assist you in determining the amount of turbine you’ll require.

Create an energy budget first. Because energy efficiency is typically less expensive than energy production, reducing your home’s electricity consumption will likely be more cost effective and reduce the size of the wind turbine you require.

The amount of power generated by a wind turbine is also affected by its tower height. A skilled installation should be able to assist you in determining the tower height required.
