The lifetime of a rotary blood pump as an artificial heart is mainly determined by the durability of mechanical parts such as bearings and seals. The purpose of this study is to develop a durable centrifugal blood pump with self-bearing motor techniques. A magnetically suspended centrifugal blood pump by using an axially levitated motor is reported. The axially levitated motor consists of a top stator, a levitated rotor, a bottom stator, and a permanent magnet bearing. The levitated rotor is set between the top and the bottom stator. The axial position of the rotor is controlled by using the electromagnets. The maximum head pressure and the maximum flow rate of the magnetically suspended centrifugal pump were 200 mmHg and 81/min, respectively. The developed pump displayed good magnetic suspension performance and sufficient pump performance as a ventricular assist device.
