This paper discusses miniaturization of a centrifugal blood pump with a magnetically levitated rotor. In the previous report, the fabricated centrifugal pump with the two-degrees-of-freedom controlled magnetic bearing was driven by the magnetically coupled brushless motor. In order to downsize the centrifugal pump, the motor should be incorporated into the centrifugal pump. A built-in motor consisting of a Halbach permanent magnet array .in a rotor and coreless coils in a stator is proposed. The advantage of the built-in motor is that unbalanced pull in the radial and axial directions of the rotor is not generated, and power consumption of the magnetic bearing to cancel the unbalanced force can be reduced. This report shows design, fabrication and performances of the centrifugal blood pump with the built-in motor.
