Abstract

1 Scope

This part of IEC 60404 is applicable to grain-oriented electrical steel strip and sheet specified in IEC 60404‑8‑7 for the measurement of magnetostriction characteristics under an applied AC magnetic field at 50 Hz or 60 Hz. This document defines the general principles and technical details of the measurement of magnetostriction characteristics of grain-oriented electrical steel strip and sheet by means of a single sheet tester and an optical sensor.

NOTE 1 The accelerometer method [5] is also an established method for the measurement of magnetostriction. However, it is more suited to the measurement of magnetostriction under an externally applied tensile or compressive stress, not zero stress, because it places a weight on the test specimen to prevent a deformation of the test specimen. Since this document includes the measurement at zero stress, the optical sensor method is provided as the optimum method.

This document is applicable to the measurement of:

– the butterfly loop ;

– the peak-to-peak value λ p-p ;

– the zero-to-peak value λ 0-p .

The magnetostriction characteristics are ...
