Research output: Contribution to journalArticlepeer-review


In previous research, we have developed a reluctance network analysis (RNA) to calculate various electric machines’ characteristics, including electric motors, with high accuracy and high speed. However, those researches were limited to the closed magnetic circuits. This paper presents a novel RNA model for open magnetic circuits with the Kelvin transformation concept. The proposed method applies to analyzing the particle accelerator magnets, wireless power transfer systems, etc.
