OPINIONS: an email on coreless motors. A conventional servo motor has a steel
core armature covered with with cable that spins in the magnets.
In a coreless design, the armature makes use of a thin cable mesh that forms
a glass that spins around the outside of the magnet eliminating the
heavy metal core. This design is significantly lighter leading to smoother
operation and quicker response time.
