This is a very cool post.
I look at that stator, and say to myself, there must be atleast 500ft of thick a## copper wire in there. It amasazes me that a 24 volt circuit generazation schedule does not "overheat" at 4000watts. Iam convinced you could very well get 4000watts from a smaller diameter stator at 12vdc with water cooled windings. The question becomes, can less torgue generate sufficiant amps to drive a 4000watt circuit, with the 9/12 arrangement. The larger diameter stators, have more holding force, at the same ampere's capacity. Finsawer?/ I agree that this could lend itself, to low speed furling charictors of large rotor("ie" 15ft dia rotor-sets). but the feature of more wiring being naturally used, in a given diameter of stator, just lends itself to more circut, per volume per phase, what I mean is this- the 3 to 4 ratio(coil to magnet) acts as a function of inverese fractil, even, in Hugh's design of this circiut. What concerns me, is the seeming use of series-parallel design, in the "star circuit". With water cooling and a delta configuration, low speed amps should be thoretically possible. Further-more "the" phase alignment acuracy, in the 9/12 (9coils to 12magnets with dual rotor=24magnets)configuration, lends itself to the possible efficiency's. What really stumps me, is that larger diameters are more condusive to phases that are out of phase (sync) by 360* degree's, versa the 120*spacing of the 912 coil-to-magnet phase arrangement.
