2. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit. The armature can be on either the rotor or the stator, depending on the design, with the field coil or magnet on the other part.

3. Generator (circuit theory) - Wikipedia

   en.wikipedia.org/wiki/Generator_(circuit_theory)

   A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. [1] These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor.

4. Dynamo - Wikipedia

   en.wikipedia.org/wiki/Dynamo

   "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

5. Armature (electrical) - Wikipedia

   en.wikipedia.org/wiki/Armature_(electrical)

   When the machine is used as a generator, the armature EMF drives the armature current, and the shaft's movement is converted to electrical power. In an induction generator, generated power is drawn from the stator. A growler is used to check the armature for short and open circuits and leakages to ground.

6. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   An induction generator produces electrical power when its rotor is turned faster than the synchronous speed.For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50 Hz.

7. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
