What is an alternator?
Q: What is an alternator?
A: An alternator is a generator which converts mechanical energy to electrical energy in the form of alternating current.
Q: Is there an alternator in every car?
A: Yes, there is one in every car, with the exception of older cars that use a DC generator.
Q: How do most alternators work?
A: Most alternators use a rotating magnetic field with a stationary armature. The armature reacts to the rotating field and carries the current caused by the rotation.
Q: Can any AC electrical generator be called an alternator?
A: In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.
Q: What is a magneto in relation to an alternator?
A: An alternator that uses a permanent magnet for its magnetic field is called a magneto.
Q: What are alternators in power stations driven by steam turbines called?
A: Alternators in power stations driven by steam turbines are called turbo-alternators.
Q: Are turbo-alternators the same as regular alternators?
A: Turbo-alternators are a type of alternator, but specifically refer to those in power stations driven by steam turbines.
