Magnetic Bearing with Melt Processed HTS
We have studied the physical processes in the contactless magnetic bearings using melt processed YBCO as a stator. We have also designed and investigated the compound bearing with the additional components from the granular HTS. The high speed magnetic rotor on these bearings with self-centering and intrinsic damping was developed. The rotor’s tolerance for its displacements, speed changes and phase disturbances was investigated. We have found the relations between the parameters of rotor’s rotation and magnetic flux dynamics in the HTS bearings. We have studied the frequency dependencies of energy losses for rotors with non-ideal magnetic symmetry and found the optimization criterion for HTS bearing designing. We have also shown that such rotors can be used as a precision device for direct investigations of energy losses in magnetic materials in alternating magnetic fields.
