Fixed electromagnet made up of an iron bar and coils; when exposed to an excitation current, it creates a magnetic field.
commutator
Conductive plates that are insulated from each other and connected to the field coil; they collect and rectify the induced alternating current.
shaft
Cylindrical part that transmits a rotational motion to the dynamo’s armature.
frame
Metal casing that houses the magnetic field.
fan wheel
Device with blades that circulates air to cool the dynamo.
armature
Moving part of the dynamo that is made up of a coil, which produces an electric current as it rotates inside the field.
coil
Conductive wire that is rolled around the armature cylinder, which rotates in the magnetic field produced by the inductor to create an electric current.
brush
Conductor that rubs against the commutator plates and transmits the continuous current produced by the dynamo to an exterior circuit.
