WebMost of U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. WebLarge-scale turbines typically rotate at 20 rpm, while domestic sized turbines tend to revolve at roughly 400 rpm. In most large-scale turbines, the low speed shaft is connected to a gearbox. The gearbox increases the rotational speed of the shaft, up to 1200-1800 rpm.
