The process of turning mechanical energy into electrical power is a marvel of modern engineering. From school experiments with magnets and coils to massive power plants with turbines spinning at high speeds, the principles remain the same but the scale is astounding. This article delves into the key components of power generators—rotor, stator, and core—and explores how they work together to produce the electricity that powers millions of homes. Discover the fascinating mechanics behind the scenes of our electrical grid and the challenges engineers face in this high-stakes industry.
