          A note on Coreless motors: conventional servo motors have a steel
            core armature wrapped with wire that spins inside the magnets.  In
            a Coreless design, the armature uses a thin wire mesh that forms a
            cup that spins around the outside of the magnet eliminating the
            heavy steel core. This design results in smoother operation and
            faster response time.
