Abstract:
A centrifuge comprising:a rotor assembly rotatable about a rotor axis, the rotor assembly being configured to hold materials for separation; a first superconducting magnetic bearing comprising; a first permanent magnet configuration coupled with the rotor assembly so as to rotate concurrently with the rotor assembly; and a passive first superconducting magnet stator being spaced apart from the first permanent magnetic configuration and the rotor assembly, the first superconducting magnet stator and first permanent magnet configuration being sufficiently close together to produce a magnetic field interaction therebetween; and a motor coupled with the rotor assembly for selectively rotating the rotor assembly, wherein the first permanent magnet configuration comprises an integrated lower part of the rotor assembly and wherein the first permanent magnet configuration comprises a first permanent magnet concentrically disposed within a second permanent magnet.
