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 an application of this motor to an artificial blood pump. A thin PM type self bearing motor has the capability of controlling χ and y direction and of giving rotating torque. Other three degrees of freedom are passively stable. In this paper, electromagnetic field analysis is apply to clarify the passive stable problem of the PM rotor using finite element method. An experimental setup is made and tested to confirm the proposed thin PM type self bearing motor. The result shows high feasibility of the use of the nonpulsatile type artificial heart.
