MAGNETIC DAMPING FOR MAGLEV

Magnetic damping is one of the important parameters that control the r esponse and stability of maglev systems. An experimental study to meas ure magnetic damping directly is presented. A plate attached to a perm anent magnet levitated on a rotating drum was tested to investigate th e effect of various parameters, such as conductivity, gap, excitation frequency, and oscillation amplitude, on magnetic damping. The experim ental technique is capable of measuring all of the magnetic damping co efficients, some of which cannot be measured indirectly.
