非晶磁性材料（AMM）已经在市场上销售了几十年。然而，它们在电机上的应用仍然缺乏突破性进展。本文提出了使用AMM的高速内部永磁转子，以避免套筒。在这种应用中，AMM的高机械强度、低铁损和相对低的饱和磁通密度的优点被充分利用。为了确保该应用的成功，对AMM的开槽、电磁性能和机械强度三个重要方面进行了实验研究。由于AMM铁芯的电磁性能对机械加工、应力和温度敏感，因此对AMM铁芯进行了测试，并将测试数据用于电机设计。最后，建立了一个原型并进行了测试。
Amorphous magnetic materials (AMMs) have been commercially available for decades. However, their application to electrical machines still lacks of breakthrough progress. This article proposes to use the AMM for a high-speed interior permanent-magnet rotor to avoid sleeves. In this application, advantages of the high mechanical strength, the low core losses, and the relatively low-saturation flux density of the AMM are fully taken. In order to ensure the success of the proposed application, three important aspects: slotting, electromagnetic properties, and mechanical strength of the AMM are experimentally studied. Since the electromagnetic properties of the AMM core are sensitive to the mechanical process, stress, and temperature, the AMM cores are tested and the tested data are used for the motor design. Finally, a prototype is built and tested.
