In recent years, the motor has been increasingly used to replace the conventional gasoline engine for carbon emission reduction, and the high-performance motor is urgently required. The stator and rotor in a motor are made of hundreds of joined and laminated electrical steels. This paper covers the current research in joining the laminated electrical steels for the motor application, together with the critical assessment of our understanding. It includes the representative joining method, modeling of the joining process, microstructure of the weld zone, mechanical strength and magnetic properties. The gaps in the scientific understanding, and the research needs for the expansion of joining laminated electrical steels, are provided.
近年来，电动机越来越多地被用于取代传统汽油发动机以减少碳排放，因此迫切需要高性能电动机。电动机中的定子和转子由数百片拼接和叠压的电工钢制成。本文涵盖了目前在电动机应用中拼接叠压电工钢方面的研究，以及对我们理解的批判性评估。它包括代表性的连接方法、连接过程的建模、焊接区的微观结构、机械强度和磁性能。文中还指出了科学理解方面的差距，以及扩大叠压电工钢连接研究的需求。
