Abstract
A centrifugal fluid pump with a fully magnetically suspended rotor to improve blood compatibility when pumping blood is disclosed. The pump stabilizes radial displacements of a disc-like rotor with active control through separate electric motor and magnetic bearings to improve the pump's critical performances including device packaging size, system simplicity and reliability, stiffness and other dynamic performances of suspension, power efficiency, and others.
