A Novel Reluctance Network Model Applicable for Open Magnetic Circuits

Abstract

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.
