This paper introduces a vector control of an induction type axial gap combined motor-bearing. The induction type motor has merits of large axial force control capability due to the flat magnetic property of the rotor. However it is difficult to control the axial force and the rotating torque independently. To solve this problem, a vector control is applied to the induction motor. The axial force and the motoring torque are analyzed theoretically and the independent control for them is developed. In order to confirm the proposed technique, an experimental motor has been made and tested. The theoretical analysis and experimental results confirm that the rotor is controlled stably and the rotating torque and the axial force are controlled independently by the proposed technique.
