I will try to improve a revolt RV120 rotor as the original one suffers from losses and heating, suspected to be from eddy currents in the magnets. My plan right now is to do a ironless halbach array rotor just for the fun of it!

Rotor shell will be made from glass fibre / carbon fibre formed on the outside of the plug,
magnets will be 84pcs of 50x4x4, they should fit the airgap diameter well.
I have abandoned the plans for 50x5x5 magnets, it will be too risky as they only barely fit with an even factor of fourteen at the airgap diameter.
I have tried to find some higher temp magnets but without luck so far..
