Scientific definitions for generator

generator
[ jĕnə-rā′tər ]

A machine that converts mechanical energy into electricity to serve as a power source for other machines. Electrical generators found in power plants use water turbines, combustion engines, windmills, or other sources of mechanical energy to spin wire coils in strong magnetic fields, inducing an electric potential in the coils. A generator that provides alternating current power is called an alternator. See also induction.
See generatrix.

Cultural definitions for generator

generator

A device that produces electric current (see also current), usually by rotating a conductor in a magnetic field, thereby generating current through electromagnetic induction. This sort of generator produces an alternating current (AC).
