Simulation of thermal processes in the screw electromechanical transformers using Matlab/Simulink

Рассмотрены полифункциональные электротепломеханические преобразователи энергии с ферромагнитным ротором, предусматривающие полное использование диссипативной энергии, структурную, функциональную и тепловую интеграцию. Выполнено математическое моделирование теплового нагрева рассмотренного устройства в среде сыпучего материала с использованием пакета Matlab/Simulink.Multifunctional electromechanical transformers of energy (METE) with a ferromagnetic rotor that foreseeing the complete use of dissipative energy, structural, functional and thermal integration are considered. The aim of work is a calculation of the thermal state of METE. To solve the problem an equivalent thermal circuit that takes into account the heat flows within the axial channel of the stator, the hollow shaft, as well as in absorption of the heat emitted from the rotor surface by heated bulk material was developed. A simulation is executed in Matlab/Simulink. The got results have good convergence with experimental data. The solving of differential equalizations of the non-stationary heating of electric machines in Matlab/Simulink differs in simplicity of realization and can be used in electromechanical transformers of energy design
