HOW STATIC PRECISION OF AN AMB ROTOR SYSTEM IS AFFECTED BY HEATING OF THE THRUST DISK

摘要

Structural designs of thrust bearings, using both actualsystem working condition as well as experimentalresults in expander applications, were used to analyzedhow the static precision of an AMB rotor systemaffected is affected by two variables – the temperatureof environment and heating of thrust disk. A model fortemperature distribution of the rotor was formulated.System static precision affected by rotor expansion andsensor temperature drift was analyzed in detail.
