Abstract

This paper describes a self-bearing centrifugal blood pump, which can be used as an artificial heart. A flat miniature squirrel-cage induction motor forms the core of the pump. Both the rotor of the induction motor and the impeller of the pump are levitated by passive and active magnetic bearings. The pump structures, design considerations, analysis of the design and time-stepping finite element simulation results of drive system and magnetic bearings, are presented in this paper.
