RE: BLDC Motor
1 You will get extra losses due to eddy currents in the Al. Can be quite significant.
2 You will reduce capacitive coupling from stator winding to rotor and yhus reduce bearing EDM. You have to make the Al conact the stator iron for that.
3 Less mechanical tolerance left for rotor excentricity and bending.
4 Internal circulation may be hindered.

Plastic will work most probably more as coating or casting in production, more difficult to achieve these thickneses for prototpe.
Thanks for your advice

If you need to put metal in between I would recommend to use stainless steel, non magnetic and quite low conductivity.
