Coreless motor, a conventional servo motor has a steel core armature
wrapped with wire that spins inside magnets. In Coreless designs,
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 is much lighter resulting in smoother operation and
faster response time.
