DC Motor Generator Setup – 42V Output Using Pulley Mechanism!


In this project, we demonstrate how to generate electricity using a simple DIY pulley mechanism. A small DC motor is used as a generator and connected to another motor that acts as a driver, powered by a 3.7V lithium-ion battery. When the driver motor spins, it rotates the generator motor using a rubber belt.

The generated voltage and current are measured using a digital volt-amp meter. As seen in the display, the generator produces a high voltage of around 42.5V, which is quite impressive considering the basic components used. This shows how mechanical energy can be effectively converted into electrical energy using low-cost parts.

The key concept here is energy transfer through rotational motion. The bottom motor (powered by battery) spins the top gear motor using the pulley and belt setup. As the generator motor turns, it induces voltage due to electromagnetic induction.

This kind of setup is commonly used in science experiments to understand the working principle of motors and generators. It is also useful for educational purposes to show students how renewable energy concepts can be applied at a small scale.

This experiment also highlights the importance of gear ratio and motor RPM in determining the final output voltage. The faster the rotation of the generator motor, the higher the voltage generated. The gear motor on the top usually has a high internal winding ratio which boosts the output.

This project is ideal for students, hobbyists, and DIY enthusiasts who want to explore the fundamentals of power generation. With basic tools and recycled components, you can replicate this setup at home and learn practically about electricity generation.
