TL;DR: In this paper, a mathematical model that allows to take into account the influence of physical phenomena, such as the nonlinearity of the magnetization curve, the hysteresis and eddy currents, on the dynamic characteristics of an induction generator was proposed.

TL;DR: In this paper, the authors simulate the self-excitation process of an autonomous induction generator by the method of regression equations, which adequately describe the dependence of the time of selfexcitation and the magnitude of the output voltage.

TL;DR: In this article, a mathematical model of the induction generator-induction motor system with parametric asymmetry was developed to determine the quality of generated electricity in load operating modes, and the results of changes in the main characteristics of an induction motor at various degrees of parametric imbalance in the generator were presented.

TL;DR: In this article, the authors have shown that the phenomenon of dust and slime emission in abrasive processing of carbon-based non-dense composites and plastics results from sliding fracture and cyclic weakening of the surface non dense layer which exhibits quasi-brittle properties under the action of fast-moving microindenters.

TL;DR: In this paper, a model of the emergence and propagation of cracks in a quasi-fragile material, particularly the carbon-carbon and carbon-polymeric composites, caused by the action of a cutting wedge is presented.
