Rotor
|
The rotor is an electro magnet. It consists of a coil of wire wound around an iron core and is pressed on to a steel shaft. It usually has 8 to 12 tapered pole projections.
|
Stator
|
The stator consists of a cylindrical laminated iron core, which carries the 3 phase winding in slots on the outside.
|
Alternator end frames
|
The end frames of an alternator are made from aluminium.
|
Slip ring & brush assembly
|
Slip rings are normally copper bands connected to the rotor winding. Brushes allow a connection to the rotating rotor winding.
|
Rectifier assembly
|
Diodes are mounted on heat sinks. The positive heat sink is insulated from the frame, the negative heat sink is connected to the frame.
|
Alternator cooling fan
|
The fan is a centrifugal type that is mounted on the rotor shaft or drive pulley.
