A bearingless motor combines the functions of both magnetic suspension and torque generation together in a single motor. Thus, it can control the radial positions of a rotating shaft without any mechanical contact. The advantages of a bearingless motor are high-speed and lubricant-free operation, no wear particles, no material wear, less heat generation, etc. The purpose of our study is to realize a compact bearingless disk motor intended for use as a centrifugal pump with small size, high durability, and contamination-free operation. In this paper, the basic characteristics of the bearingless disk motor have been verified. The experimental results demonstrated the feasibility of an application of the bearingless disk motor to a centrifugal pump.
