For the spread of small fuel cells, it is important to improve the performance of peripheral devices including fuel supply pumps, and to lower a price of them. A miniature diaphragm pump can utilize as a fuel supply pump, however it has many problems. Therefore, we propose small regenerative pump using axial self-bearing motor. The unidirectional type Axial Self-Bearing Motor that has a function of producing motor torque and controlling axial position of the rotor enables miniaturization and reducing cost. In this paper, a structure of the pump and control system are introduced, and results of pump efficiency are shown.
