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 raidal AMBs, and an axial AMB. Therefore, it is possible to downsize the AMB system with maintaining high performance. In this paper, a 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 analytic condition is set that the motor torque is 30mNm, the control force is quintuple of the rotor gravity (5G), and the diameter of the outer rotor is 50mm. The results showed the feasibility of the downsizing of the propose outer rotor type 5-DOF self-bearing motor.
