Design and Performance Test of High-Speed Motor/Generator for the Flywheel Energy Storage System

플라이휠 에너지 저장 장치용 초고속 전동발전기의 설계 및 특성시험

This paper treated the design and performance test of high speed motor/generator used in the flywheel energy storage system. The unique characteristics of the motor in this paper is the it doesn't contain any magnetic material. The field system was constructed by using Halbach array that generates the magnetic field with the permanent magnet only. The armature was also composed of plastic bobbin and winding. This paper shows the design results have a good agreement with the experimental results.
