Interesting I would have thought the PM rotor would be the way to go along with it being wound as (?)36 volt making it easier to gain rpm through voltage change... am I off in my thinking? In what ways are they better and would the controllers be cheaper for the A/C gen2? PS thanks for the advice
The problem with the Gen1 versus Gen2 is: Gen1 is still a claw-pole alternator with a wound rotor and a brush/slip ring assembly for feeding power to the rotor, and subject to the same efficiency problems as the standard alternators that people usually get 1500W controllers, and the maximum that i saw them using (with Cycle Analysts) was 100A, both at 36V (youtuber Fixitmoditbreakit) and 48V (youtuber Austiwawa), albeit with a tad more efficiency because of the magnet help on the rotor, so the magnetic flux will also be bigger and give a bit more torque, while the Gen2 is a full ACIM power unit, with 115V @ Star and 67V @ Delta, following info that i saw here in ES and ElMoto forums.

I did a while back, re-read it I am wondering if it is a claw style rotor with magnets assisting a wound rotor... the only style I had seen disassembled is the gen2 versions
The Gen2 is indeed more focused by its power capabilities, but if you want to see the Gen1 disassembled, check those 2 links:

And i also found a thread with watercooled alternators that were similar to the Gen1, but watercooled
