How Static Precision of an AMB Rotor System is Affected by Heating of the Thrust Disk

Structural designs of thrust bearings, using both actual system working condition as well as experimental results in expander applications, were used to analyzed how the static precision of an AMB rotor system affected is affected by two variables – the temperature of environment and heating of thrust disk. A model for temperature distribution of the rotor was formulated. System static precision affected by rotor expansion and sensor temperature drift was analyzed in detail.
