I'd solder the connections after pressing them in. Using high melting point solder might be good there too (but it's even better if these parts don't get hot enough to worry about that).
On your rotors, it might be good if there was a small lip on the OD to help keep the magnets from flinging off at high speeds. I don't trust glue that much. Also, if the rotor hub was mild steel, it could help the back iron or replace the back iron.
