摘要: Abstract The effect of multi-axial stress on the iron losses a non-oriented electrical steel sheet under alternating magnetization is analyzed. Multi-axial magneto-mechanical measurements M400-50A grade are performed by using custom made single tester device. measured separated into hysteresis, classical and excess loss components statistical theory, various configurations hysteresis By utilizing an equivalent model magneto-elastic invariant based derived. These models can be used to predict evolution even if only uniaxial dependent available. accuracy both found satisfactory when they identified from measurements. shown slightly more accurate for studied material.
