Development of Miniaturized Regenerative Pump using Axial Self-Bearing Motor

摘要

This paper describes the structure and performance of miniaturized regenerative pumps with an axial self-bearing motor. Two types of pump are introduced: a single-type pump, which has one flow channel on one side of the rotor driven by a single-type axial gap self-bearing motor, and a push-pull-type pump, which has two flow channels on both sides of the rotor driven by a push-pull-type axial gap self-bearing motor. Pump performance and efficiency are evaluated, and the feasibility of the proposed pumps is discussed.
