IPM型スパイラルモータのモデル化・特性解析および基礎駆動試験

抄録

We propose a new linear actuator, named Spiral-motor, which has more advantage than conventional linear motor. Spiral-motor consists of a mover and a stator with spiral structure. Our first prototype of Spiral-motor has a ball-screw to keep constant air gap between mover and stator, and has surface permanent magnets (SPM). In this paper, we present a new Spiral-motor, which does not have ball-screw and has interior permanent magnets (IPM). Also, we analyze characteristics of the new Spiral-motor by permeance method and finite element method, and consider magnetic levitation control by simulation.
