碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 95 === This thesis aims at the study on a brushless DC motor (BLDCM) applied to a vehicle by means of the finite element method (FEM). The efficiency and operation properties of the BLDCM will be affected when altered the geometry of the BLDCM. Therefore, the FEM will be employed to discuss the magnetostatic analysis and transient properties of the BLDCM in this thesis. More specifically, the electromagnetic torque and the cogging torque of the BLDCM will be assessed when altered the geometries such as the alterations of the thickness of the permanent magnet, the air gap, and the shape of the stator of the BLDCM. Additionally, the design of experiments (DOE) will be employed to find out the maximum electromagnetic torque and minimum cogging torque.
