How One Motor Powers Two Fans Using Pulley Mechanism – Simple DIY Project!


In this exciting experiment, we show how a single DC motor can power two separate fans using a clever pulley mechanism. It’s a simple yet effective demonstration of mechanical energy transfer and distribution – perfect for anyone interested in basic engineering concepts.

The system uses one DC motor connected to a battery, and two small fan blades attached to rotating shafts. A thread or rubber belt connects the motor shaft to the other fan shaft through pulleys, allowing the rotation of one motor to drive multiple loads simultaneously.

As the motor spins, it pulls the thread which in turn rotates the pulleys attached to the fans. Both fans start spinning efficiently even though only one motor is used. This setup showcases how rotational force can be shared using a simple mechanical system.

This type of mechanism is commonly used in various machines where one source of power needs to drive multiple components. It's also an excellent demonstration for science fairs or school projects to understand basic motion, torque, and force distribution.

The materials used in this project are very basic – a DC motor, fan blades, rubber band/thread, pulleys, and a power source. No complex circuit is required, which makes this ideal for beginners and young learners.

Overall, this project is a fun and educational way to explore the fundamentals of mechanical energy and engineering. It proves that with just a few common items, one can create interesting machines that serve real purposes.
