F&P smartdrive Stator/Rotor magnetic relationship

[Cylon]

Can somebody maybe enlighten me as to what stator belongs with what rotor.
seems to be 2 kinds of each (stator with heavy copper around 7.5 ohms stator with light copper sometimes under 6 ohms low as 1.5)
Rotor with about 3″ composite magnets, stator with individul steel magnets.
As I mostly refurb machines from scrap, its not allways obvious. what belongs with what
I have however discovered in interesting cure for a phantom rps problem that wont go away, no matter how many sensors and controllers you change.
Change the magnet and bingo away she goes, maybe the fields weaken, I dunno, seems the composite magnet allways works for this problem.
even when it did not originally have this one fitted./
Also the little brass strip that jumpers the windings together gets corrosion, causes strange things. Pull it and clean the contacts then recheck with meter.

Phase 1 stator – resistance 1.3 ohms at room temperature.
Phase 2 – 4 stator – resistance 6.1 ohms at room temeperature.
Phase 5 on stator – resistance 16 ohms at room temperature.
Phase 5 stator has smaller connector tabs as well.
