Abstract

PURPOSE: The magnetic pole for leakage flux is attached to the magnetic pole of permanent magnet being covered by damping ring so that it can increase eddy-current loss without changing magnetic absorbtion power and improve stability of rotation by increasing damping effect of supported body.
