COMMENTS:
A note on coreless engines: a regular servo motor has a steel
core armature wrapped with cable that spins within the magnets. In
a coreless design, the armature makes use of a thin cable mesh that forms a
cup that spins round the outside the magnet eliminating the
heavy metal core. This design leads to smoother operation and
faster response time.
