AC Generator

An AC or alternating current generator is a piece of machinery that produces AC electricity. Most commonly this machine is powered by steam.in simple terms it consists of a series of blades that are turned by steam.a magnetic field is excited on the rotor which then cuts through lines of magnetism that are present on the stator by the power grid. As more power is applied to the rotor, the turbine must spin harder,not faster, to push more power onto the grid. RPM of rotor is determined by the number of poles in the stator. Most commonly a turbine will spin at 3600rpm.... or, 60 times per second giving us the USA electrical grid a 60Hz frequency. This is scratching the paint on AC generation but its a start.
