A synchronous generator is a type of electrical machine that converts mechanical energy into electrical energy. It operates at a constant speed, synchronized with the frequency of the electrical grid. This means that the generator's rotation speed is directly related to the frequency of the electricity it produces, making it essential for maintaining stable power supply. These generators are commonly used in power plants, where they are driven by turbines powered by steam, water, or wind. The rotor of the generator creates a magnetic field, which induces an electric current in the stator windings, generating electricity efficiently and reliably.
