碩士 === 正修科技大學 === 機電工程研究所 === 98 === Because permanent magnet brushless DC micro-motors are small in volume, light, highly efficient and reliable, they have a potential development in the microminiaturization and high quality of electronic products. This study researches for a more systematic design and analyzes the brushless DC motor to reduce cost and improve the quality of the motor performance using the permanent magnet brushless DC micro-motor that drives the motor’s cooling fan as the research tool. In the traditional design, analytical method was used to compute for the design parameter and performance parameter of the permanent magnet brushless DC motor to establish a permanent magnet mathematical model. In the parameterization and optimization design considerations, traditional magnetic circuit analysis can’t effectively finish the task. Thus, this study combined the magnetic circuits. First, magnetic circuit method was used to design the initial specification of the motor. Then, the constructed finite element model analyzes the design parameter and performance of the motor through the software JMAG-Studio to improve the performance of the design analysis.
