“…Boundary conditions are then applied to these matrices, such as Neumann conditions that leave the matrices unchanged or Dirichlet conditions that remove rows and columns corresponding to boundary nodes where the solution components are already known. The system of linear equations is then constructed and solved using some of the known methods [30].…”

This article presents the design of a drive system for robots and manipulators, which is based on the finite element method of an induction motor. The design process involves constructing a computer-aided design (CAD) model of the induction motor, which enables the generation of design documentation and control programs for computer numerical control (CNC) tools for manufacturing motor parts or conducting further research. A CAD model is developed for performing a finite element analysis of the motor in the SolidWorks software based on the popular AIR63V2 motor. The design of the motor’s housing, rotor, and stator is developed. Additionally, the electrical parameters of the motor are calculated using Ansys Electronic Suite—Maxwell RMxprt, utilizing the classical analytical theory of electrical machines and the equivalent magnetic circuit method. This takes into account such effects as the non-linearity of electrical steel, the non-sinusoidality of the magnetic flux in the gap, and the displacement of electric current in massive conductors. A complete model of an induction motor for research has been created, enabling the study of dependencies of speed and electromagnetic torque of an induction motor. The natural frequency of the rotor is calculated, which ranges from 922 Hz to 1015 Hz. The obtained values of calculations of natural oscillations of the CAD model of the motor can be used for motor diagnostics. Furthermore, the created project in the Ansys software can be utilized to design an induction motor with its own characteristics, optimized for specific tasks.

“…Based on the latest literature, technology that uses sorption on natural and synthetic sorbents has a dominant position in the water treatment process. It is advantageous if locally available, economically undemanding natural materials and methods are used [Macala 2009[Macala , 2017Pandova 2018, Panda 2014, 2018a,b, 2019Valicek 2016and 2017, Balara 2018, Monkova 2013, Gombar 2013, Murcinkova 2013, Bielousova 2017, Flimel 2018, Krehel 2013, Flegner 2019, 2020Mrkvica 2012, Pollak 2020, Olejarova 2017, Rimar 2016, Zaborowski 2007, Michalik 2014, Straka 2018aBozek 2021].

The article presents the results of research on reducing the concentration of heavy metals, such as copper and nickel, on natural zeolite in comparison with synthetic zeolite and chemically treated natural zeolite. The reduction of the content of specific types of heavy metals from aqueous solutions was investigated by the method of sorption kinetics. The results indicate the ability of natural zeolites to compete with synthetic zeolites.
