The compressor shall be provided with axial and
radial magnetic bearings to levitate the shaft,
thereby eliminating metal-to- metal contact, and
thus eliminating friction and the need for oil. The
magnetic bearing system shall consist of front,
rear, and axial bearings. Both front and rear
bearings levitate the shaft in the axial and
radial planes. Each bearing position shall be
sensed by position sensors to provide real-time
repositioning of the rotor shaft, controlled by
onboard digital electronics.
