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