Abstract
In order to develop a ventricular assist device which have low power consumption and wide operating region, a double side stator type axial self-bearing motor was proposed and developed. In addition, the motor was combined in a magnetically levitated pump. The axial self-bearing motor is characterized by the inclination motion control function. The self-bearing motor was fabricated and its fundamental characteristics as were measured. In addition, the magnetically levitated pump was designed with 3D-CAD and was fabricated by a rapid prototyping. The motor could rotate stably and rotation speed was up to 4,000 min^<-1> both in air and in water.
