A technique for flexible control of induction baking of electrically non-conductive layers (paints, varnishes, resins, etc.) is presented, based on the temperature prediction. As the numerical solution of the full model of the process takes a long time, it is necessary to approximate&#x...

This paper describes the development of electrically insulating hybrid steel–composite cross-arm for mediumvoltage overhead distribution power lines with three conductors. The main goal was to achieve substantial weight savings ompared to a common steel cross-arm with three ceramic insulators widely&#...

In the introduction of the presented work, the physical nature of the collapse of electrical energy transmission systems due to the influence of a magnetic storm is recalled. A mechanism is described by which, due to the non-linearity of the magnetic circuit of the system'...

Magnetic actuation methods for miniature robots are widely used thanks to their massive applications for precise micro-manipulations in inaccessible or hardly accessible environments, including medical and biological operations. The system studied is composed of miniature robots with permanent magnets ...

The article introduces a Special Issue (SI) of the journal Electronica that contains fourteen chosen articles from robust design optimization of electrical machines and devices. Optimization is essential for the research and design of electro-mechanical devices, especially electrical machines. Finding...

Severe collapses caused by anomalies in the Earth's magnetosphere, known as geomagnetic storms, have been reported in the operation of transmission power systems. A semi-saturating phenomenon occurs in which geomagnetic currents are induced very in high voltage lines, which cause the pow...

Two powerful and versatile code packages (Agros Suite and Artap) are presented for design and optimization of technical devices and systems. Agros Suite represents an environment for numerical solution of systems consisting of partial differential equations (PDEs) of the second order by ...

The Teplator is a nuclear heat-only reactor under development in the Czech Republic, which uses already irradiated spent nuclear fuel (SNF). This study aims to assess the feasibility of integrating this technology with district heating systems (DHSs) compared with other heating technologies....

There is a great potential in small satellite technology for testing new sensors, processes, and technologies for space applications. Antennas need careful design when developing a small satellite to establish stable communication between the ground station and the satellite. This work is&#x...

Control systems for every simulator have to be fast and precise. These are exact properties that are needed when designing a paraglider simulator. With it’s complex set of controls and complicated aerodynamics physics, paraglider simulator requires a very precise system to mimic it’s&#x...

This paper deals with kinematics and the design and implementation of the paraglider simulator drives. Part of this article contains the necessary calculations, that are important for the mechanical design and manufacture of drives. There are given reasons which led to using 3D pri...

In the operation of large-scale power systems for the long-distance transmission of large amounts of electricity, a number of cases have been reported in which anomalies in the Earth’s magnetosphere, referred to as geomagnetic storms, have caused a severe system collapse. Changes in...

The operational reliability and high efficiency of modern electrical machines depend on the ability to transfer heat in the construction parts of the machine. Therefore, many authors study various thermal models and work on the development of effective heat dissipation. New insights and...

The bio-inspired algorithms are novel, modern, and efficient tools for the design of electrical machines. However, from the mathematical point of view, these problems belong to the most general branch of non-linear optimization problems, where these tools cannot guarantee that a global ...
