Do not embed any olher conductive substances (apart from the coils) in ti,e stator casting or the magnets will induce ele tric currents in them, wasting power and heating the stator up. Go through a 'dry run' where you check that it all fits together before waxing the mottld. Place a piece of glass clotb into ti,e bottom, then slide the coils in carefully with the wires at the chosen exit point.

This means Ulat the back of the new magnet will be repelled by the first magnet of the first disk. Place it onto the second disk at the index mark without turning it over. The top faces of the two first magnets will now attract each other. Go ahead and place the rest of the magnets, alternating them as before. These magnet rotors are now hazardous items that can hurt people if they come together with each other unexpectedly. You can lose a finger. Store them carefully. Keep them away from work areas with metal swart and dust that would stick to the magnets and be hard to remove.
