This was how it went Lutach,

When we started doing destructive testing, we found that the rotors that were wrapped handled higher temperature than those that were unwrapped -- even though there was no difference at low temp. Turns out that the glue is stronger than the magnet material at lower temps, but at higher temps the glue gets a little soft, and the wrap helps keep the magnets in place.

Also, we found that a wrapped rotor usually didn't destroy the stator when it failed (the wrap helped cushion the blow to the stator) where the unwrapped rotor usually did destroy the stator (and pieces of magnet got EVERYWHERE in the stator.)
