Magnetostriction strain measurement: heterodyne laser interferometry versus strain gauge technique

Setareh Gorji Ghalamestani UGent, Lieven Vandevelde UGent, Joris J.J. Dirckx and Jan Melkebeek UGent (2013) 5th International Conference on Optical Measurement Techniques for Structures and Systems, Proceedings. p.164-174
abstract
Deformation of the ferromagnetic material, known as magnetostriction, causes vibrations and noise of electrical machines and transformer cores. A setup by using heterodyne laser interferometers has been built to measure the magnetostriction strains as a function of the applied magnetic field. The measurement results on a sample of nonoriented electrical steel are presented in this work. These results are compared with those obtained by using a strain gauge setup. The laser measurements are less disturbed by noise, especially for measurements under low amplitude magnetisation. In addition, contrary to the strain gauge samples, the sample preparation for the laser setup does not require removal of the protective coating. Measurement results on the coated samples are highly helpful for the calculation of the magnetostriction noise of the device. The coated samples show smaller deformation, since the coating applies tensile stress to the material. For the case of the same nonoriented material the reduction of the magnetostriction strains in amplitude is about 20%.
