thanks for the time. the winding scheme description is not my bread and butter but i am familiar with it. looking at my notes (wich are horrible) i was using to different info sources and at the time not seeing the whole picture . learned i did.
in an effort to maintain magnet fill and use the same magnets ill make a run at a custom stator.
If i could bother you one more time ? going with the 1/2 inch diameter mags x 18 what would be the optimal slot count. ? and winding scheme ?
thanks again olaf-lampe
with 18 mags, the best suitable number of slots would be 27. The diameter of the rotor is something above 93mm ( sorry no inches
I would make the airgap as small as possible, because of the odd surface of the mags.
I would rethink the use of rounded mags here, because the inner ironring for the rotor is pretty difficult to build. Maybe you can build a simple ring and glue on the mags with ironpowder/epoxy mix up to the lower half of the mags. But I wouldn't bet on any high RPM capability...
As a prove of concept it would work, but how much would you pay for useable
You can still use them as a charming bracelet
BTW: If you want something easy to diy a BLDC check ebay for Studer / Revox A77 motors
from old HIFI- bandmachines. I have some mags for them, too.
