The maglev technology offers long lifetime and better biocompatibility of the blood pump by eliminating the mechanical contact components from the device. We have developed a miniaturized maglev blood pump for an artificial heart for neonate and infant. Target length and diameter of the designed pump are 33.4 mm and 24 mm, respectively. The pump consists of a self bearing motor and a levitated rotor impeller. The self bearing motor which suspends the rotor impeller in the axial direction, consists of electromagnetic cores, two poles permanent magnets on the both surface, and electromagnet coils for rotor position, rotation and tilt control. The self bearing motor was designed based on magnetic field analysis. Experimental results indicate sufficient magnetic suspension performance of magnetically levitated motor.
