The coupled effect of heat and stress on the magnetic properties of electrical steel laminations is measured using a novel single-strip tester (SST) that applies uniaxial stress and localised heating to a sample. Magnetic characteristics, such as hysteresis curves, power losses and permeability, are produced as a function of stress, whose effect varies with temperature. The proposed system improves on existing systems by removing the need for a furnace, ring samples and large stressing apparatus.
