RNA-Based Optimum Design method for SPM type Magnetic Gears

摘要

??Magnetic gears, which can change torque and speed without any mechanical contacts, have some advantages in comparison with conventional mechanical gears as follows: low vibration and acoustic noise, high reliability, and low maintenance. This paper presents an optimum design method for a surface permanent magnet (SPM) magnetic gear based on reluctance network analysis (RNA). The RNA has desirable features including a simple analytical model, high-speed and accurate calculation, and ease of coupled analysis. The validity of the proposed method is proved by comparing with another method based on finite element analysis (FEA) and experiment.
