Abstract The article proposes an analysis of the possible architectures of synchronous machines with an ability to operate at high temperatures of over 200°C in their environment. Two machine principles have been considered: the permanent magnet synchronous machine and the synchronous reluctance machine. The numerical analyses are carried out with 3D-coupled electromagnetic-fluid-thermal models; the electromagnetic one provides the local losses that give the input data to the coupled thermal-fluid analysis model for computing the temperatures inside the machines. The simulation results are used for estimating the temperature limit of each machine architecture, considering the characteristics of their critical parts.

高温同步电机的架构选择

摘要 本文提出了对能够在其环境中在超过 200°C 的高温下运行的同步电机的可能架构的分析。已经考虑了两种电机原理：永磁同步电机和同步磁阻电机。数值分析是用 3D 耦合的电磁-流体-热模型进行的；电磁模型提供局部损耗，将输入数据提供给耦合热流体分析模型，用于计算机器内部的温度。考虑到关键部件的特性，仿真结果用于估计每种机器架构的温度限制。
