Your run of the mill GM 10SI unit charges at aprox 1200rpm.
AC Delco parts sells an alternator which is designed for low rpm use, its
output starts at about 1000 rpm.
You won't find anything that puts out anything substantial below 1000rpm.
What will be turning this alternator? And if its automotive use, you should
look into a dual batter setup to drive your accessories if your pushing the
limits of things.

If your after a GM, a single wire regulator is available for the 10SI
(standard 70's alternator) from your AC Delco parts counter.  It has the
field and stator terminals--but they are dummy terminals.
This regulator is good for upto 100 amps, and if the parts guy is having
difficulty locating it, its a marine part.
Most rebuilt 10SI units are rebuilt to 63amps.  More than enough for most
applications. Note the *most applications* =)
