高速电机（HSEMs）已广泛应用于当今的许多应用中，并且在汽车行业中越来越受到关注。然而，HSEMs存在许多特殊的设计挑战。本文旨在总结和讨论HSEMs的主要挑战和设计考虑因素。本文还提出了克服这些挑战的解决方案。讨论了高速电磁场的四个主要损耗分量，并进一步说明了降低各损耗分量的方法。还比较了HSEMs的轴承选项。此外，还详细讨论了转子动力学和结构挑战，并提出了一些设计建议和考虑因素。概述了散热和冷却方面的挑战。最后，电力电子电路的挑战也被证明，并提出了一些解决方案。因此，本文提供了一个正确的技术选择和设计的HSEMs和相关配件的指导方针。
High-speed electric machines (HSEMs) have been widely used in many of today's applications and are gaining more attention in the automotive industry. However, many special design challenges exist for HSEMs. This paper aims to summarize and discuss major challenges and design considerations for HSEMs. Solutions to overcome these challenges are also offered in this paper. Four major loss components of HSEMs are discussed and the methods to reduce each loss component are further explained. Bearing options for HSEMs are also compared. In addition, the rotor dynamics and structural challenges are discussed in detail, followed by some design suggestions and considerations. Thermal and cooling challenges are presented as an overview. At the end, the challenges for power electronics circuitry are also demonstrated and are followed by some proposed solutions. Thus, this paper offers a guideline for proper technique selection and the design of HSEMs and associated accessories.
