A Motor Made With Fiberglass
What I'm thinking is that with a steel frame underneath to provide some basic strength and then fiberglass on top you could build a Halbach motor with just basic tools.
The idea would be to wire up all the magnet wires for the stator side and then just embed everything in fiberglass. For the rotor side (where you place the permanent magnets) you build something with steel that will be where the bearings are attached and then embed that steel frame with the magnets so that everything gets glued together. Add fiberglass cloth as you do the embedding and that will reduce the chance of things cracking.
I've found that with the brushed motors that fiberglass can handle the heat very well as long as it's not directly in contact with current. (like as a commutator which is just too much) For things like the magnet wires the fiberglass is able to deal with that level of heating.
Anyway... it might be possible...
...it might be a good idea to buy some carbon fiber cloth.
