Word Origin and History for generator
1640s, "person or thing that generates," from Latin generator "a begetter, producer," agent noun from past participle stem of generare (see generation). Meaning "machine that generates power" first recorded 1794; in sense of "machine that generates electric energy," 1879. Fem. generatrix attested from 1650s.
- One that generates, especially a machine that converts mechanical energy into electrical energy.
- 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.
