Why choose a coreless servo? 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 thin wire mesh that forms a cup that spins around the outside of the magnet eliminating theheavy steel core. This design results in smoother operation and faster response time.
