We developed a compact centrifugal blood pump utilizing a combination of an axially-controlled magnetic bearing (MB) and an axial flux motor. An experimental pump was 65 mm in diameter and 35 mm in height. The rotor having a six-vaned impeller of 52 mm in diameter could levitate and rotate at a rotational speed of up to 3,000 rpm without contact. It could yield a flow rate of 5 L/min. against a head pressure of 100 mmHg. In order to decrease the axial thrust induced by the unbalance of fluid force working on the rotor and reduce the power consumption of the MB, the arrangement and diameter of balance holes through the rotor were surveyed using computational fluid dynamics (CFD) simulation.
