  2. 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 ...

  3. Magneto - Wikipedia

    en.wikipedia.org/wiki/Magneto

    Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in telephone systems.

  4. Alternator (automotive) - Wikipedia

    en.wikipedia.org/wiki/Alternator_(automotive)

    Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.

  5. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.

  6. Alternator - Wikipedia

    en.wikipedia.org/wiki/Alternator

    Alternator mounted on an automobile engine with a serpentine belt pulley (belt not present.) Alternators are used in modern internal combustion engine automobiles to charge the battery and to power the electrical system when its engine is running. [citation needed] Until the 1960s, automobiles used DC dynamo generators with commutators.

  7. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage. [ 1 ]

  8. Linear alternator - Wikipedia

    en.wikipedia.org/wiki/Linear_alternator

    A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent. The principal difference is in how they are used and which direction the energy flows.

  9. Rotary converter - Wikipedia

    en.wikipedia.org/wiki/Rotary_converter

    The rotary converter can be thought of as a motor–generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric ...
