The maglev technology offers long lifetime and better biocompatibility of blood pumps by eliminating the mechanical contact components from the device. We have developed a miniaturized maglev blood pump for an artificial heart with a diagonal flow pump which allows higher pump head than axial pumps and smaller size than centrifugal pumps. The pump consists of two magnetic bearings, a motor, and a levitated rotor-impeller. The magnetic bearing, which suspend the rotor-impeller in the radial direction, consists of electromagnetic cores, permanent magnets, and electromagnet coils. The magnetic bearing and the blood flow path were designed using magnetic field analysis and CFD analysis, respectively. Target length and diameter of the designed pump are 70 mm and 50 mm, respectively. Simulation results indicate sufficient magnetic suspension and pump performance
