A machine built as an induction motor and driven above synchronous speed, thus acting as an alternating-current generator; -- called also asynchronous generator. Below synchronism the machine takes in electrical energy and acts as an induction motor; at synchronism the power component of current becomes zero and changes sign, so that above synchronism the machine (driven for this purpose by mechanical power) gives out electrical energy as a generator.
An induction generator is an induction machine, driven above synchronous speed by an external source of mechanical power.
A device that converts the mechanical energy of rotation into electricity based on electromagnetic induction. An electric voltage (electromotive force) is induced in a conducting loop (or coil) when there is a change in the number of magnetic field lines (or magnetic flux) passing through the loop. When the loop is closed by connecting the ends through an external load, the induced voltage will cause an electric current to flow through the loop and load. Thus rotational energy is converted into electrical energy.
A generator that produces energy by the production of a magnetic field by the proximity of a electric charge. Commonly made from old induction motors.
this type of generator operates in parallel with the utility for its phase, frequency and voltage and cannot operate in isolation (stand alone), in other words it cannot operate without the power company.
A type of electrical generator that is mechanically and electrically similar to a polyphase induction motor. Induction generators produce electrical power when their shaft is rotated faster than the synchronous frequency of the equivalent induction motor. Induction generators are often used in wind turbines and some micro hydro installations due to their ability to produce useful power at varying rotor speeds.
