The new method of continuous centrifugal separation instead of dialysis membrane has improved the quality of life of patients with kidney disease who depend on hemodialysis treatment. As a result, the research on artificial kidney pumps has been paid much attention by many scholars, but the conventional artificial kidney pump is supported by rolling bearings, and it thus causes problems such as high hemolysis and high thrombosis rate. In order to solve these problems, this paper developed a compact and energy-saving single-degree-of-freedom controlled magnetic levitation bearing applied to an artificial kidney pump by using the advantages of non-contact, non-lubrication, and high rotation speed of magnetic levitation bearing. The finite element analysis software was used for simulation to explore the design parameters of the radial passive control part and the axial active control part, and the overall simulation was verified. Then the structural performance of the magnetic levitation bearing was evaluated. The results show that the simulated and experimental radial displacement stiffness coefficients are 47.432 N/mm and 49.531 N/mm; the axial current stiffness coefficients are 0.144 N/AT and 0.135 N/AT, and the axial displacement stiffness coefficient is 223.071 N/mm, which meet the requirements of five-degree-of-freedom stable suspension of this magnetic levitation bearing. The designed magnetic levitation bearing simplifies the system structure, reduces the control difficulty, and lowers the power consumption of the system.
