Maglev technology realizes long lifetime and better biocompatibility for centrifugal blood pumps by eliminating the mechanical parts from the device. A new hybrid magnetic bearing with a double biased magnetic flux was invented as a high performance magnetic levitation system for blood pumps. The magnetically suspended motor with the hybrid magnetic bearing and a maglev pump was constructed and evaluated its performance. A levitated rotor-impeller is set between the magnetic bearing and a motor stator in the maglev motor. Maximum pressure head and maximum flow rate are 146 mmHg and 12.4 L/min, respectively. The maglev motor was miniaturized by three dimensional finite element method. The diameter of the rotor is reduced from 72mm to 50mm and miniaturized maglev motor indicates sufficient magnetic suspension performance as a result of simulator.
