Magnetic bearing controller screen
Figure 21: Magnetic bearing controller screen
The MBC screen displays the orientation of the magnetic bearing axes relative to the compressor
driveline. Pertinent parameters transmitted to the control panel from the magnetic bearing
controller (MBC) are displayed on this screen. Many parameters are shown in the diagram in the
locations they represent. The left end of the motor shaft graphic represents the low stage, a single
stage, impeller end bearing. The right end of the motor shaft graphic represents the opposite end
bearing.
