alternator![click to hear](/images/speaker.jpg)
Generator of alternating current that is used especially in the automobile industry (powering electrical devices) and in power houses.
frame ![click to hear](/images/speaker.jpg)
Metal casing that houses the magnetic field.
shaft ![click to hear](/images/speaker.jpg)
Rod that is rotated by the pulley, which in turn causes the claw-pole rotor to rotate.
drive pulley ![click to hear](/images/speaker.jpg)
Mechanical unit integrated with the shaft; it is rotated by a belt that is connected to an engine.
collector rings ![click to hear](/images/speaker.jpg)
Insulated conductor collars that are connected to the coil of the field; they gather the induced alternating electric current.
brushes ![click to hear](/images/speaker.jpg)
Conductive parts that rub against the collector rings and transmit the current produced by the alternator to an outside circuit.
field winding ![click to hear](/images/speaker.jpg)
Conductive wire on the cylinder rotor; when exposed to an excitation current, it creates a magnetic field.
armature core ![click to hear](/images/speaker.jpg)
Fixed cylinder with a winding; the rotor turns within it to produce the electric current.
claw-pole rotor ![click to hear](/images/speaker.jpg)
Moving cylindrical part made up of a field winding between two pole shoes; it creates the rotating magnetic field required to operate the alternator.
armature winding ![click to hear](/images/speaker.jpg)
Conductive wire on the armature; the rotor moves in front of it to produce an alternating current.
fan wheel ![click to hear](/images/speaker.jpg)
Device with blades that circulates air to cool the alternator.
