Miniaturization of a Magnetically Levitated Axial Flow Blood Pump

open access: yesArtificial Organs, 2010
AbstractThis article introduces a unique miniaturization process of a magnetically levitated axial flow blood pump from a functional prototype to a pump suitable for animal trials. Through COMSOL three‐dimensional finite element analysis and experimental verification, the hybrid magnetic bearings of the pump have been miniaturized, the axial spacing ...
