I don't find you to be argumentative at all. Your posts seem very well mannered to me, and I appreciate your comments. What sort of gets my goat is when people pop up on forums like these with patronizing or arrogant comments, or being downright rude and making personal attacks. But none of that is going on here. We're just kicking some ideas around, and I think it is great.

Have you seen John Eargle's document about magnet structures? It illustrates motors with static flux symmetry and those without, and it compares alnico, ferrite and flux stabilized ferrite magnets.
