Alternating current generators, typically referred to as AC generators, generally work on the same principle as direct current generators.The basic function of a generator is to convert motion into electricity. Providing... More »

Wind turbines turn the kinetic energy of the wind into mechanical energy and then electricity through the use of a shaft and a gearbox that power an internal generator. Sensors in the wind turbine allow it to turn and ad... More »

Windmill generators work by capturing the kinetic energy of blowing air and converting it to electric energy using copper coils and magnets. The wind pushes the wind turbine blades, which turn an axle. The axle, usually ... More » Science Physics Electricity

The primary difference between brushless and brush generators lies in their method for transferring DC power from the exciting current to the generator's magnetic fields. According to, generators produ... More »
