摘要：
The magnetostrictions in a non-oriented electrical steel sheets are an important cause of motor vibrations and noises. The presence of non-sinusoidal magnetic flux density brings about larger vibrations and noises. In this paper, a standard monolithic measurement system is employed to measure the magnetostriction in a non-oriented electrical steel sheet when a third harmonic is overlapped on a pure sinusoidal magnetic flux density. Based on the analysis of measured magnetostrictive property, a dynamic estimation model of magnetostrictive strain is proposed and verified. The results are helpful for further investigation of motor vibrations and noises.
