- 論文の詳細を見る
Magnetic bearings have been widely used to support rotors without physical contact. Since a power motor has a configuration similar to that of the magnetic bearing, a self-bearing motor is investigated in this study, which has functions of both a rotary motor and a magnetic bearing. In this paper we introduce an application of this selfbearing motor to an artificial blood pump. The thin Permanent Magnet(PM)-type self-bearing motor has the capability of controlling x and y directions and of giving a rotating torque actively. Other three degrees of freedom are passively stable. In this study, electromagnetic field analysis is applied to clarify the passive stability problem of the PM rotor using the bite element method. An experimental setup is made and tested to confirm the applicability of the proposed thin PM-type self-bearing motor. The results show a high feasibility of using this motor in the fabrication of a nonpulsatile-type artificial heart.
