A 5-DOF self-bearing motor has been proposed to achieve a compact active magnetic bearing (AMB) system. The 5-DOF self-bearing motor possesses the functions of a motor, two radial AMBs, and an axial AMB. Therefore, it is possible to downsize the AMB system with maintaining high performance. In this paper, interior permanent magnet (IPM) type 5-DOF self-bearing motor is proposed. It is analyzed to realize the further downsize for the application of an artificial heart using 3 dimensional finite element method. The analytic condition is set that the motor torque is 30mNm, the control force is quintuple of the rotor gravity (5G). The optimization result shows the sufficient miniaturization for an application of the artificial heart pump.
