    The calculation results of the static field parameters for permanent magnet linear synchronous motor have been presented in this work. The influence of the construction temperature on the parameters has been analyzed mathematically. Models for magnetic and temperature fields determination have been formulated. Two kinds of permanent magnets (NdFeB and SmCo) have been considered. The distribution of the thermal field has been obtained using the finite element method (FEM).

    Opis:
    In this paper, a three-air-gapped structure of a ferrite core for a resonant inductor is proposed. The electromagnetic and thermal field models are built using a 3D finite element method. Compared with the conventional signal-air-gapped structure of a ferrite core, the simulation and analysis results show that the proposed three-air-gapped ferrite core resonant inductor can reduce eddy-current loss and decrease temperature rise. In addition, the optimal position of air-gapped is presented.

    Opis:
    Maintaining railway turnout operability is crucial for ensuring railway transport safety. Electric heating of railway turnouts is a significant technical and economic issue. The classical heating is characterised by high power consumption. For this reason, research is needed to optimise the current system. This paper presents results of a numerical analysis and of experimental researches. The numerical analysis was carried out using the ANSYS software. There was conducted a numerical comparative analysis of energy loss during heating performed using two different heaters. Including the classical method and a heater thermally insulated from a rail. In the first step, heating of a working space filled with a substitute snow model was considered. The snow-covered surface area was held within the working space of the turnout. It was assumed that the snow substitute material had thermal properties approximately the same as real light snow. It was also assumed that the material is in the solid state which would not undergo a phase change. In the next step, a real snow model that included the phase change process was taken into account. The energy efficiency and heat distribution in the turnout have been analysed and compared. The experimental researches were carried out in a physical model. The results showed that the use of a contactless heater results in creating a larger area over which emitted heat affected snow in the working space. Consequently, more snow was melted around the contactless heater than the classic one. This experimental observation supported the results of the numerical analyses presented previously.

    Opis:
    This paper describes the application of the skull melting method for an artificial generation of particulate material of inorganic compounds like CsOH, NaOH, SnO2 and UO2. The skull melting process is analyzed analytically. Thereby the electromagnetic field is calculated by a one dimensional time harmonic model. Thermal losses are estimated by simple analytical formulas. Finally an electromagnetic thermal field coupling is performed to calculate the temperature distribution inside the crucible, considering transient thermal effects. The skull melting process is simulated for the example of UO2. Under consideration of the given material properties it is shown that the skull melting method can be applied to fuse UO2.

    Opis:
    The in-wheel motor is installed in wheels, and road excitation acts on the in-wheel motor directly through a wheel, which affects the flow field characteristics of the motor’s liquid cooling system, and affects the thermal field characteristics of the in-wheel motor. Aiming at this problem, the in-wheel motor drive system is taken as the research object in this paper. Firstly, the heat flow coupling analysis model of the in-wheel motor drive system is established by using the heat flow coupling theory. Then the vibration response of in-wheel motor stator and shell under different road excitation obtained from the previous study is taken as the load. Finally, thermal field characteristics of the water-cooled the in-wheel motor under different working conditions are studied, and the influence law of different speed and road grades on the thermal field characteristics is obtained. The results show that under the road excitation, the maximum temperature of each component of the in-wheel motor decreases due to the vibration effect of road excitation on the flow field of the cooling system, and the decrease of the stator and winding is the most obvious. Additionally, the higher the speed, the greater the road roughness coefficient, the greater the temperature drop of each component of the in-wheel motor. However, the thermal field distribution of local parts of the motor is relatively uneven under road excitation, which leads to greater thermal stress of the local parts and increases the risk of motor damage.
