I believe the one I took apart was a Delco. It was given to me
by an alternator shop just for that purpose. It had been discarded
as unrepairable.

90% of the alternators in use have brushes. You pay a LOT extra for a
brushless alternator. Electrodyne, Niehoff, Denso and Delco all make
brushless alternators but you pay a premium for them. I lucked up on a
250
amp brushless Niehoff and a normal Leece-Neville as spare.

In a brushless the stator and the field coil are both mounted in the case.
The rotor is just a piece of iron with a finger pattern. The field coil
induces a magnetic field in the rotor which generates AC current in the
Stator coil.

Some alternators have a stationary field coil excited by
residual magnetism. The one I disected must have been one
of those.

Alternators don't have brushes


You might be right!...... but then, how does the current get from the
rotor to the outside of the alternator??? Hmmmmm?
