MAGNETIC BEARING CONTROLLER SCREEN

FIGURE 14 - MAGNETIC BEARING CONTROLLER SCREEN

OVERVIEW
This screen displays the orientation of the magnetic
bearing axes relative to the compressor driveline. Per-
tinent parameters transmitted to the control panel from
the Magnetic Bearing Controller (MBC) are displayed
on this screen. Many parameters are shown in the dia-
gram in the locations they represent. The left end of the
motor shaft graphic represents the Impeller End Bear-
ing. The right end of the motor shaft graphic represents
the Opposite Impeller End Bearing.
