Design of a Self-Bearing Slice Motor for a Centrifugal Blood Pump

This paper introduces a radial type self-bearing slice motor. It has the capability of giving rotating torque and controlling radial gap magnetically. Other degrees of freedom are passively stable. This paper introduces the application of this motor to an artificial blood pump. The results of a simple experiment are described and passive stability is discussed. Finally a new design of self-bearing motor with a centrifugal pump is introduced which is under development.
