Magnetic bearing has been widely used to support rotor without physical contact. Since power motor has the similar configuration of magnetic bearing, a self-bearing motor was considered and reported. This has both functions of rotating motor and magnetic bearings. This paper introduces a passive stability analysis and an application of this motor to an artificial blood pump. A thin PM-type self-bearing motor has the capability of controlling x and y direction and of giving rotating torque. Other three degrees of freedom and passively stable. Electromagnetic field analysis is applied to clarify the passive stability of the PM rotor using finite element method. An experimental setup of the artificial blood pump is made and tested. The result shows high feasibility of the use for nonpulsatile type artificial heart.
