Repurposing Old Appliance Motors into Wind Turbines: A Guide to Sustainable DIY Energy Generation


The concept of sustainability has never been more important than it is today. With the increasing awareness about climate change and the need for renewable energy, many are looking for creative ways to contribute. One such way is by turning unused home appliances into wind turbines. This blog post delves into the possibilities of using old motors from various appliances to build your own wind turbine.

The Potential of Old Motors

Washing Machine Motors

Washing machine motors are often induction motors that are robust and long-lasting. They are designed to handle high torque, making them ideal for wind turbines. These motors can generate around 500-750 watts of electricity, depending on the wind speed and the efficiency of your setup.

Dryer Motors

Similar to washing machine motors, dryer motors are also robust and can handle high torque. However, they are generally smaller and might produce less electricity, around 300-500 watts. They are suitable for smaller setups or as a supplementary unit to a larger system.

Balance Board Motors

These motors are generally smaller and less powerful but are incredibly efficient. They are perfect for low-wind areas and can produce around 100-200 watts. Their lightweight nature also makes the setup more manageable.

Electric Drill Motors

Electric drill motors are compact and highly efficient. They are designed for high RPM (Revolutions Per Minute), which makes them ideal for wind turbines. These motors can generate around 200-400 watts.

Treadmill Motors

Treadmill motors are designed for high torque and can generate a significant amount of electricity, around 750-1000 watts. They are also readily available and relatively cheap to acquire.

Creative Possibilities

Blender Motors

Though not commonly considered, blender motors are small but can be highly efficient. They are suitable for very small setups, perhaps for charging small devices, and can generate around 50-100 watts.

Fan Motors

Old ceiling or table fan motors can also be repurposed. They are generally less powerful but can be used in tandem with other motors to increase the overall capacity.

Vacuum Cleaner Motors

These motors are designed for suction but can be reversed engineered for generating wind electricity. They can produce around 100-300 watts and are generally compact.

Why These Motors?

The motors mentioned above are not just randomly picked; they have characteristics that make them suitable for wind turbines. These include:

  1. High Torque: Essential for starting the motor with low wind speed.
  2. Durability: These motors are built to last and can withstand outdoor conditions when adequately protected.
  3. Efficiency: Most of these motors convert a high percentage of mechanical energy into electrical energy.

High torque motors are typically used in applications where a lot of rotational force is required. Other examples of high torque motors include:

  • Washing machine motors
  • Dishwasher motors
  • Vacuum cleaner motors
  • Blender motors
  • Food processor motors
  • Power tool motors

Low torque motors, on the other hand, are typically used in applications where less rotational force is required. Examples of low torque motors include:

  • Fan motors
  • Pump motors
  • Printer motors
  • CD/DVD player motors
  • Clock motors


Turning unused home appliances into wind turbines is not just a DIY project but a step towards sustainability. It’s a creative and effective way to repurpose old motors, reducing waste and generating renewable energy. So, the next time you think of discarding that old washing machine or drill, consider giving it a second life as a wind turbine.
