Well, Todd, there are many advantages to having an alternator rather
than a generator in nearly any vehicle application, not just for
loopframes. The advantages would be, in no particular order:
1) Rated output at lower RPM's than a comparable generator.
2) No commutator to wear out.
3) Reduced brush wear due to the fact that on a generator the armature
(rotor) output is carried by the brushes. On an alternator the brushes
ride on slip rings and carry the field current, which is much lower.
4) Modern alternators usually have the voltage regulator built in.
5) Higher amperage output from a similar package size.
6) Less "hash" and electrical noise.
All that having been said, there is one HUGE disadvantage in trying to
graft an alternator to a loopframe. It is nearly impossible to find one
that will directly bolt in place of the generator. Therefore,
installation of an alternator will probably adversely affect the looks
of what is becoming a "classic" bike.
