A 5-DOF self-bearing motor has been proposed for achieving 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 while maintaining its high performance. In this paper, a downsized outer rotor type 5-DOF self-bearing motor is proposed for the application to an artificial heart pump. An experimental setup was fabricated based on the analytical results obtained by a three-dimensional finite element analysis and was then tested. The proposed outer rotor type 5-DOF self-bearing motor proves to have a sufficiently applicable performance for use as an artificial heart pump.
