COMMENTS:
A note on coreless motors-a traditional servo motor has a steel core
    armature wrapped with wire that spins inside the magnets. In a
    Coreless style, the armature utilizes a wire mesh that forms a cup
    that spins around the outside of the magnet. This plan is
    much lighter resulting in smoother operation and faster reaction
    time.
