A Prototype Design of a Demonstration Model of a Pendulum Driven Generator

The researchers came up with an idea of creating a design of a demonstration model of a generator using pendulum as the prime mover. The pendulum will be using its own weight to drive the generator in order to produce electricity. The oscillation of the pendulum will serve as the main turning force for the rotor of the generator, containing permanent magnets to produce a rotating magnetic field. This will then be surrounding the stator containing series of coils or conductors around an iron core that creates an inductor. As the pendulum swings, the generator is able to produced electricity. The idea is to design a demonstration model of a pendulum that drives a generator where the pendulum’s energy loss from air resistance can be neglected. Addition of a counterweight in the pendulum would increase its amplitude. Through this, the duration of the pendulum will increase. Results show that a 90° amplitude of the pendulum from rest, produced the highest output. Since the pendulum releases energy as it swings it will eventually stop. In this project, the generator was able to produce electricity without using any non-renewable sources like the common generators using gasoline and diesel engines as prime mover. The generator as of now has an efficiency of 38.355% but the output of the generator may still be increased improving its by purchasing a bigger generator.
