How does an automotive alternator work? |
[Edit] |
Answer
Winding a coil of wire around an iron core can make a magnet. If a magnet is passed near a wire, an induced current will flow in that wire. If many magnets are rapidly passed over a coil of wire, much more induced current will be produced. If many magnets are passed over several coils of wire, even more current will be produced.
Although Alternators vary by manufacturer, there are two elements common to all alternators; the stationary stator and the rotating rotor. The stator consists of three sets of individual windings wound around a laminated circular iron stator frame. Each individual winding is made up of seven coils, which in turn are made up of several individual loops all connected in series. Each coil and each loop are connected so as to increase the total voltage output. Each group of windings has only two leads, one for current to flow in, and the other for current to flow out.
