I have more than 100 used computer hard discs waiting for disassemling and making next generator. It means more trouble than disassembling 12 microwawe owens.
Read my older diary about single phase machine using wery old computer scasi drive magnets. Definately Neodynamium magnets are much better, I noticed it when I was not able to separate this double rotor machine without tools.
This microwawe maget machine is double rotor machine too. Only pictures here taken from early stadium.
I was able to separate second magnet rotor from machine by two hands. Of course stator thichness was same, same mold used.

I had same idea to make weak microwawe magnets stronger by adding additional neodynamium magnets to ferrite magnet hole.
But I read from this forum that Neodynamium magnet can kill Ferrite magnet soon.
And I was afraid and let holes empty.
Is it true?

I hope to add some more pictures soon.

BR,
