A power generator is a machine that converts mechanical energy into electrical energy. It exists to provide electricity when direct access to a centralized power grid is unavailable, unstable, or insufficient. The basic principle behind electricity generation is electromagnetic induction, where motion within a magnetic field produces electric current.
Power generators have been part of modern society for over a century, supporting early industrial activity, lighting systems, and transportation. Over time, their role expanded into residential backup power, industrial operations, healthcare systems, and remote infrastructure.
Today, generators are essential components of energy systems, ensuring continuous electricity supply across different environments.
