本文报道了一种无取向电工钢板在不同磁通和应力条件下的磁特性测量结果，提出了一种考虑应力对电机铁芯影响的矢量磁特性分析方法。本文研究了应力对电机磁通密度矢量、磁场强度矢量和磁功率损耗的影响，以提高电机的性能。因此，假设的应力分布应用于定子铁心的局部部分，并使用应力复合和建模进行矢量磁特性分析。从这些结果可以看出，磁场强度矢量的位置和磁功率损耗随应力分布的变化而变化。通过施加可控的局部应力分布，可以减小磁功率损耗。
We have reported the measured results for the magnetic properties of a non-oriented electrical steel sheet under various magnetic flux and stress conditions and proposed a new vector magnetic characteristic analysis technique to consider the stress effect on the motor core. In this paper, the stress effect on the magnetic flux density vector, magnetic field strength vector, and magnetic power loss is examined to improve the performance of electric motors. Thus, the assumed stress distribution is applied to the local part of a stator core, and the vector magnetic characteristic analysis is performed using stress-complexandmodeling. From these results, the loci of the magnetic field strength vector and the magnetic power loss differed by changing the stress distribution. It was possible to decrease the magnetic power loss by applying a controlled local stress distribution.
