I read on some sight somewhere a bloke used a car alternator and took out the regulator and diodes. He had to feed part of the output into the rotor via the brushes which the diodes and regulator normaly do and he got quite a bit of three phase a.c. Obviously he had his bike in a stand.

With Neo magnets, and a 1725 rpm single phase motor (thirty six slots i believe), a fairly nice output can be had .
guys have used up to a 7.5 HP baldor motor , with a skewed stator to prevent cogging.
by skewing the stator you dont have to skew the rotor and the rotor magnets can be in a strait line.
of course no skewing is needed for an axial flux alternator/generator
