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