COMMENTS

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.
