A note on Coreless motors. A conventional servo motor has a steel
core armature wrapped with 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 is much lighter resulting in smoother
operation and faster response time.
