“…24 a,b, is that the presence of airvent spacers implies, when applying a compaction effort, the appearance of noticeable mechanical stresses in the plane of the electrical steel sheets. According to the literature 1 , 17 , mechanical stresses in the plan have a significant effect on magnetic properties. These effects are described in Table 4 , for the stress ranges given by the Abaqus simulations, in terms of qualitative impact on the magnetic properties.…”

The manufacturing processes of electrical machines may lead to significant degradation of the magnetic properties of their magnetic core (stator, rotor) performances and, as a consequence, to a decrease of their energy efficiency. While the effects of some processes (cutting, welding …) are widely discussed in the literature, this is not the case with the compaction process although it is systematically used to maintain the assembly of electrical steel sheets that compose the magnetic circuits. In addition to the conventional one, a specific compaction process exists for high-power electrical machines. After an introduction, the paper firstly deals with the two studied processes (conventional, specific). Then, an experimental mock-up to study the impact of the two configurations on the magnetic properties (iron losses, normal magnetization curve) is presented. This mock-up is the first, in the literature, that allows to study the effect of a controlled compaction mechanical stress on magnetic properties. Obtained results in both configurations highlight a magneto-mechanical effect that is not reported in the literature where these effects are commonly considered following in-plane mechanical stresses. This paper presents a magneto-mechanical model, taking into account the compaction stress effect, as well as a modelling protocol to model the effect of 3D mechanical stress on magnetic properties, which has never been done in the literature.

“…Such a problem can be split into two categories: (a) uniaxial (the applied uniaxial stress is in the direction of the applied magnetic field) and (b) multiaxial (multiaxial stress is applied or the uniaxial stress is not in the direction of the applied magnetic field). The uniaxial problem does not generally suffer from stress non-uniformity and was the subject of numerous works [23][24][25][26][27][28][29][30][31][32][33][34][35]. The sample shapes can be parallelepipedal [23], [27], [28], [32], [35] or cylindrical [31].…”

Ferromagnetic materials exhibit nonlinear magnetic behavior, and many are anisotropic. Their magnetic characterization requires a mappingin excitation and measurementof the magnitude and direction of the magnetic field H or magnetic induction B. While many previous works have treated different parts of the characterization problem, the question of measurement reliability was not always adequately addressed. The present work relies on key assumptions made in characterization experiments to propose three criteria that form a necessary and sufficient condition for reliable measurements: (1) material properties are assumed homogeneous in the measurement region (uniformity criterion), (2) measured H is assumed to be equal to that giving rise to the measured 𝑩 (correspondence criterion) and (3) B&H directions are assumed known (direction criterion). Both theory and simulation are used to quantitatively assess the fulfillment of these assumptions using various apparatuses found in the literature along with new setup designs. Both alternating and rotating field loadings are considered for linear and nonlinear behaviors, using isotropic and anisotropic materials in both 1D and 2D excitation and measurement systems, with and without applied mechanical stress. The derived criteria are then used to establish guidelines for accepting, rejecting, and improving experimental apparatuses and offer clear insight into the measured data. In general, and when the application allows it, surface measurements of both B&H are recommended, 1D excitation systemsthough limited to certain applications -fulfill the criteria the most, and finally, while the excitation can be 1D or 2D the measurement should always be 3D.
