2. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. [20] With the advancement in semiconductor technology, brushless alternators are possible. Smaller brushless alternators may look like one unit, but the two parts are readily identifiable in the large ...

3. Brush (electric) - Wikipedia

   en.wikipedia.org/wiki/Brush_(electric)

   A pair of carbon brushes. A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1]

4. 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.

5. 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.

6. Compensated pulsed alternator - Wikipedia

   en.wikipedia.org/wiki/Compensated_pulsed_alternator

   A compensated pulsed alternator, [1] also known by the portmanteau compulsator, is a form of power supply. As the name suggests, it is an alternator that is "compensated" (see below) to make it better at delivering pulses of electrical energy than a normal alternator.

7. 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.
