Definitions for "Induction generator"
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.
