- High Performance Halbach Array Motors Using Multi-Physics Optimization Design
説明
<p>As acceleration of worldwide electrification, companies are competing in research and development of motor system, which are used as the main power source of electric vehicles. The performance requirements such as high power, high efficiency, and high density make efficient design and development of motors essential by combining multi-physics simulation with analysis problems from various fields such as structure, electromagnetic field, mechanism, fluid, and acoustics. The motor performance is affected by not only magnetic circuit but also materials properties. It is required a coupled analysis of the magnetic field and heat transfer in the motor design. Levels of mechanical vibration and noise usually are varied with weight and efficiency of motor. In this study, a Halbach array motor with high power density and high efficiency was employed, and a multi-objective optimization design was performed using JMAG and modeFRONTIER with bi-directional coupled magnetic field and thermal analysis, and then, vibration and acoustic analysis was conducted for the preferred solution with high power density and high efficiency. As a result of the optimization, a preferred solution was obtained that increased power density and efficiency and suppressed temperature rising as compared with the base model. Vibration and noise were also estimated.</p>
