From Wikipedia, the free encyclopedia (Redirected from Generator set ) NRC image of Modern Steam Turbine Generator. In electricity generation , an electrical generator is a device that converts mechanical energy to electrical energy . The reverse conversion of electrical energy into mechanical energy is done by a motor ; motors and generators have many similarities. A generator forces electric charges to move through an external electrical circuit , but it does not create electricity or charge, which is already present in the wire of its windings. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine , water falling through a turbine or waterwheel , an internal combustion engine , a wind turbine , a hand crank , compressed air or any other source of mechanical energy.
