alternator
Generator of alternating current that is used especially in the automobile industry (powering electrical devices) and in power houses.
shaft
Rod that is rotated by the pulley, which in turn causes the claw-pole rotor to rotate.
drive pulley
Mechanical unit integrated with the shaft; it is rotated by a belt that is connected to an engine.
collector rings
Insulated conductor collars that are connected to the coil of the field; they gather the induced alternating electric current.
brushes
Conductive parts that rub against the collector rings and transmit the current produced by the alternator to an outside circuit.
field winding
Conductive wire on the cylinder rotor; when exposed to an excitation current, it creates a magnetic field.
armature core
Fixed cylinder with a winding; the rotor turns within it to produce the electric current.
claw-pole rotor
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
Conductive wire on the armature; the rotor moves in front of it to produce an alternating current.
