We propose a novel configuration of magnetic bearing for left ventricular assist device (LVAD) to realize simple and small LVAD. The magnetic bearing consists of a cylindrical stator with an inner ring and an outer ring and a rotor. The magnetic bearing and a displacement sensor have a hollow as a flow channel. In order to simplify the system, the magnetic bearing has the one axis controlled rotor in the axial direction. The displacement sensor coil in the axial direction is put in the center of stator. In this study, the displacement sensor is applied to the magnetic bearing and investigated. Magnetic field analysis was performed in order to evaluate magnetic flux of permanent magnet and force in the axial direction. Some experiments for levitation and rotation were performed.
