实际旋转机器中的电工钢板在交变和旋转磁通量条件下被磁化。另外，电工钢板的磁性能受到机械应力的强烈影响，并由于制造过程中的残余应力而劣化。因此，了解各种应力和磁通量条件下的磁性能非常重要。在本文中，我们研究了交变磁通量条件下机械应力对矢量磁性能的影响。根据结果，我们可以得出结论，电工钢板的矢量磁性能取决于机械应力和励磁方向。因此，在电机设计中考虑矢量磁特性和机械应力非常重要。
Electrical steel sheet in actual rotating machines is magnetized under alternating and rotating magnetic flux conditions. In addition, the magnetic properties of the electrical steel sheet are affected by mechanical stress strongly and are deteriorated due to the residual stress during the manufacturing process. Therefore, it is important to know the magnetic properties under various stress and magnetic flux conditions. In this paper, we investigated the effect of the mechanical stress on vector magnetic property under alternating magnetic flux conditions. Basing on the results, we can conclude that the vector magnetic property of the electrical steel sheet depends on the mechanical stress and the excitation direction. Therefore, it is important to consider the vector magnetic property with the mechanical stress in the design of the electrical machine.
