热性能是确定参数和选型的关键。本文首先分析并建立了轴向磁通永磁电机和径向磁通永磁电机温升计算的等效热网络模型。在此基础上，分析比较了相同体积的AFPM和RFPM在不同电机参数（每槽导线数、极弧系数、永磁体厚度、气隙长度、槽尺寸等）下绕组和永磁体温升的变化规律。计算结果与实测温升数据的对比验证了所提ETNM的正确性。
Thermal property is a key issue for the parameter determination and machine type selection. In this paper, the equivalent thermal network models (ETNMs) for temperature rise calculation of axial flux permanent magnet motor (AFPM) and radial flux permanent magnet motor (RFPM) are analyzed and built up respectively at first. And then, the temperature rise change regulation of winding and permanent magnet of AFPM and RFPM with the same volume were analyzed and compared considering the different machine parameters which are the number of conductors per slot, polar arc coefficient, permanent magnet thickness, air gap length and slot size et.al. Finally, a prototype of AFPM is trial-manufactured and tested. Comparison between the calculated date and the tested data of temperature rise verifies the correctness of the proposed ETNMs.
