The main alternator works by using the alternative configuration that has a rotating discipline and stationary armature. A bridge rectifier, known as the rotating rectifier assembly, is mounted over the rotor. Neither brushes nor slip rings are employed, which reduces the number of wearing pieces. The primary alternator has a rotating area as described over plus a stationary armature (electrical power generation windings).
