Hello,
I can't find the magnets. However from the strength they must be ceramic. The pole pieces on the rotor are cast into aluminum and are made of laminated steel. I sanded the greenish paint off of one of them and did a scratch test. The mags must lie underneath the pole pieces.

The magnets may be Alnico or similar under the poles or perhaps more likely Ceramic blocks on edge with those poles acting as flux concentrators, that would be the only way to get the area in that space. The slots in the poles cast full of aluminium are damper bars and act like the cage bars in a squirrel cage rotor.
