This motor rotor is a small diamagnetic neodymium cylinder 3 x 10mm. It spins along its longitudinal axis at speeds up to 32,000 RPM and has a precessional rotation of 4,000 RPM. This rotor is not silent - producing a sound not dissimilar to a fly.
During development, speeds of over 80,000 RPM were achieved using this rotor !
