Abstract

Aiming at small high-speed rotating machines, this paper proposes a Lorentz force type self-bearing motor, where a new four-pole winding configuration is used to make it function both as a synchronous permanent-magnet motor and as a magnetic bearing. Due to using Lorentz force dominantly, the proposed motor has some good points such as linearity of control force and facility of design and analysis. And compared with the 8-pole type previously developed, it is advantageous at high speed. Focusing on the feasibility of the proposed motor, this paper introduces a prototype, which is manufactured in disk type with an outer rotor and successfully run up to 12600rpm without contact. Static and dynamic characteristics of the prototype are examined.
