碩士 === 逢甲大學 === 電機工程所 === 95 === On the design and analysis of motors the thermal problem is an important subject because the size and life of motors are affected by the thermal characterization. Thermal analysis of a brushless permanent magnet motor is presented in the thesis. First, the finite element analysis software, Flux 2D is employed to obtain the average flux density of each region of the motor, and then based on the results to calculate the losses. They are the input of the thermal analysis. Finally, the 3D thermal analysis model of the motor is established and thermal parameters, such as convection exchange coefficient, thermal conductivity coefficient etc. are derived. The temperature distribution of the motor is obtained using 3D steady state thermal analysis.
