![]() Electromagnetic coils imbedded in the MB provide forces to stabilize the shaft position at the target via sensing and control stages. The operating environment of the EEC-T550 Sm-Co magnet more » material could be extended by implementing active cooling. UHT–PMs were produced and used in the MB actuator. ![]() The Phase I efforts was to focus on development and demonstration of component technologies and detailed design of full scale components and a demonstrator test rig for use in Phase II. The 6-pole homopolar design permits uninterrupted force delivery via a redundant control capability (US patent 7,429,811) even if 3 poles were to fail. The choice of material is the UHT Sm-Co PMs (US patent 6,451,132) due to their significantly better thermal stability. The proposed novel MBs combine PMs for supplying the bias field and electromagnets for supplying the control field, both in UHT conditions. The MB test environment will include 700☌, 40krpm and 4,000 psi requirements to advance the supercritical carbon dioxide (sCO 2) and other types of Brayton power cycle systems. This project will develop a PM biased MB system, that is actively cooled to the 550☌ maximum operating temperature limit of PMs. The goal of this project is to design and construct of a prototype of ultra-high temperature permanent magnet (UHT–PM), which provides the force to pull the spinning shaft towards the target position in the magnetic bearing (MB) clearance circle.
