中文摘要：

非晶合金材料由于其高导磁、低损耗的特点，在电机的研究、开发中受到了广泛和密切的关注。由于非晶合金电机常常运行在变频控制下且工作频率往往较高，电机内谐波含量大、发热严重。考虑到电机损耗、材料导热性能、散热面对流传热性能受温度分布的影响，将温度场计算程序与一套双重循环迭代系统相嵌套，计算7kW盘式非晶合金永磁电机的三维温度分布。通过系统内循环确保电机腔内空气温度的准确选取；通过外循环计及温度分布对损耗、导热系数以及对流传热系数的影响。从有限公式迭代算法的基本原理出发，通过对温度场数学模型的改进，简化循环中对导热系数修正的计算过程，降低每步迭代的计算量。通过对比迭代算法算得的温升分布和电机温升实验结果，验证了模型的合理性和计算结果的准确性，为盘式非晶合金永磁电机的温度分析计算提供了一种较为精确、快捷的参考方法。

英文摘要：

The amorphous alloy(AA)lamination has attracted extensive research attentions in motor design because of its superior characteristics of high magnetic conductivity and low power loss density.Since the motors utilizing AA cores are mostly operated under the frequency conversion control systems,the heat generated may cause high temperature rises and limit the thrust output.The field analysis of thermal behavior of a7kW axial flux permanent magnet(AFPM)motor with an AA core is embedded with a double-circulation procedure.The inner loop of the system is used to verify the fluid temperature.The outer loop is used to judge veracity of losses,heat conductivity coefficients,and heat convection coefficients.The temperature field analysis technique based on cell method(CM),also known as finite formulation method(FFM),is modified to simplify the rewind process of heat conductivity coefficients and reduce the computing work introduced by iteration.The calculation system is validated by experiments,and proves to be a valid and simple candidate for temperature distribution analysis of AFPM motors utilizing AA cores.
