Abstract
The subject of the study is cores for new energy-efficient electric motors used in industrial robots and metal-processing complexes. The aim of this work is to select and calculate an optimal structure of advanced soft magnetic composites that ensure manufacturability and reduction of power losses in the motor's magnetic system over a wide frequency range of supply voltage. The theoretical foundations of modeling additive electromagnetic properties and the assessment of the influence of the specific volume content and characteristics of the filler and binder matrix in the composite on the magnetic permeability of the material were considered. A comparative analysis of heterogeneous medium models was carried out according to J.C. Maxwell, K.W. Wagner, O. Wiener, and V.I. Odelevsky. A computational experiment was performed. The results indicated the possibility of applying linear approximation to the calculated curves of the dependences of the magnetic permeability of dispersed-filled composite materials on the specific volume content of the filler. This approach may simplify the task of choosing the best solution to achieve the required magnetic properties of the compositions in the future. The results of experimental studies of the physical and magnetic properties of dispersed-filled soft magnetic composites under laboratory conditions were presented as an experimental approbation of this technique. The potential advantages and disadvantages of using new materials in the manufacture of electrical machines and devices were analyzed. The performance indicators achieved on experimental samples revealed an insufficient level of their magnetic permeability. Therefore, an important direction for developing this topic is the digital synthesis of predictive models for new soft magnetic composite materials. This model must take into account the structural state and the development of production technologies that reduce design costs and production time of the electrical machines of required standard sizes. These improvements can help overcome the constraints hindering the development of autonomous transport and robotic complexes.
