bled on the inside of a laminated core that is attached to
the generator frame. The rotor revolves within the stator
on bearings located in each end frame. Two brushes are
required to carry current throught the two slip rings to
the field coils wound concentric with the shaft of the rotor.
Six rectifier diodes are mounted in the slip ring end
frame and are jointed to the stator windings at three
internally located terminals.
