Abstract
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, an outer rotor type 5-DOF self-bearing motor is analyzed to realize the further downsizing for the application of an artificial heart using 3 dimensional finite element method. The analytical condition is set that the motor torque is 0.03Nm, the control force is quintuple of the rotor gravity (5G). The results show that the downsized 5-DOF self-bearing motor is applicable for an artificial heart pump.
