A new type of combined motor-bearing is proposed. It is intended for a rotor to have two functions of rotary motor and radial magnetic bearing. In the previous works, P±2 pole algorithm has been proposed to realize combined motor-bearing function. But the construction and the control system was complicated. In this paper, hybird active magnetic bearing(HB AMB)type combined motor-bearing is proposed with used DC magnetic flux to control radial force. The structure is the combination of hybrid type magnetic bearing and PM type AC motor. First, the fundamental operation of the proposed hybrid AMB type combined motor-bearing is explained. Then the minimum pole number that realizes the independent control of levitation and rotation is derived theoretically. Finally, the experimental setup is made to confirm the capability of the proposed motor. The results show high stability and strong rotating torque of the proposed motor-bearing.
