How does the magnetic field affect the alternator?
The stator winding develops voltage and current begins to flow from the induced magnetic field of the rotor. The rotor winding assembly rotates inside the stator winding. The rotor generates a magnetic field. Kevin Sulli van, all rights reserve d. www.smcccd.cc.ca.us/smcccd/faculty/sullivan Understanding the Alternator
How does a revolving armature on an alternator work?
The revolving armature type has the armature wound on the rotor, where the winding moves through a stationary magnetic field. The revolving armature type is not often used. The revolving field type has magnetic field on the rotor to rotate through a stationary armature winding.
How is the rotor connected to the alternator?
• The rotor contains the field winding wound over an iron core which is part of the shaft. • Surrounding the field coil are two claw-type finger poles. • Each end of the rotor field winding is attached to a slip ring. Stationary brushes connect the alternator to the rotor.
How is the voltage of an alternator adjusted?
Excitation current or field current generates magnetic flux in the rotor. Thus, by adjusting the excitation current, the magnetic field can be adjusted. And by adjusting the magnetic field the voltage in alternator or generator terminal can be adjusted or regulated.

How does the voltage regulator adjust the alternator field?
The voltage regulator adjusts a small field current that connects to your ignition system, battery and alternator rotor windings. The alternator field current is substantially lower than the current output the alternator produces while operating.
What are the advantages of rotating field over rotating armature in alternator?
Actually the thing with the rotating Armature is that you might be able to collect the AC current via Slip-Rings but there is always a risk of spark due to coil inductance which if propagates would surely damage the armature The Rotating Magnetic field (RMF) on the other hand is very advantageous because
