永磁爪极电机是一种特殊的横向磁通电机，与传统电机不同，其主磁路是三维的。因此，为了准确的性能分析，需要三维有限元法（FEM）来计算电磁特性和热分布。然而，这是耗时的，特别是当耦合效应需要考虑。本文提出了一种结合三维磁网络和热网络的方法来获得PMCPM的性能。由于所开发的热网络与磁网络具有相同的结构，因此计算出的铁损可以很容易地被视为热分析中的热源，其中，由于采用了3D网络，因此可以计算3D旋转铁损。该方法具有磁热耦合紧密、计算速度快等优点，并采用三维有限元法对计算结果进行了验证。
The permanent magnet claw pole machine (PMCPM) is a special kind of transverse flux machine, different from conventional electrical machines the main magnetic flux path of PMCPM is 3D. Therefore, for accurate performance analysis,the 3D finite element method (FEM) is required to calculate both the electromagnetic characteristics and thermal distribution. However, it is time consuming especially when the coupling effect needs to be considered. In this paper, a combined 3D magnetic and thermal network method is proposed to obtain the performance of PMCPM. As the developed thermal network shares the same structure as the magnetic network, the calculated core loss can be regarded as the heat source in the thermal analysis easily, in which 3D rotational core loss is calculated as the 3D network is adopted. The proposed method holds the advantages of close magnetothermal coupling and fast calculating speed.For the calculation results verification, 3D FEM is used.
