TL;DR: In this article, a permanent magnet synchronous machine associated with a gearbox for a screwdriver application was designed based on a purely analytical formulation, and the optimization of the pole pair number and the choice of the gear ratio was discussed.

TL;DR: In this paper, the effect of mechanical stress on the magnetic loss of electrical steel sheets is analyzed utilizing the statistical loss theory, and the model and its correlation with the hysteresis loss are validated by performing comprehensive measurements at various combinations of induction levels, frequencies and stresses.

TL;DR: In this paper, a novel approach for predicting magnetic hysteresis loops and losses in ferromagnetic laminations under mechanical stress is presented, which is based on combining a Helmholtz free-energy-based anhysteretic magnetoelastic constitutive law to a vector Jiles-Atherton model.

TL;DR: In this paper, the effect of multi-axial stress on the iron losses of a non-oriented electrical steel sheet under alternating magnetization was analyzed by using a custom made single sheet tester device.

TL;DR: In this article, a simplified multiscale approach and a Helmholtz free energy based approach for modeling the magneto-mechanical behavior of electrical steel sheets are compared.
