Interest paid lately to brushless direct current motors made the researches regarding the optimum design and construction of these motors to be very present. The study carried out, by the simulations we presented, shows that these motors have high torque oscillations in a complete rotation. There are identified the slots which create high torques, respectively low torques, in a complete rotation,...
This paper presents a procedure to optimize the structure of the two magnetic coupled coils used in the wireless power transfer systems (WPTS's). The optimization of the two magnetic coupled coils is performed in function of the alignment coils. There are two forms of deviation in the alignment of coils — the lateral displacement and the angular displacement. In the lateral displacement, the two coils...
In this paper is proposed an optimized solution of DC electromagnet using design of experiments (DOE) and FEM. Before optimization, the technique of screening was applied to determine the most influent geometrical parameters on the static force characteristic. For this purpose, the response function was chosen to be the root square of the average of squares of the relative force for five values of...
The Distributed Generation (DG) systems of today face a multitude of problems, among which the pollutant emissions and the energy efficiency play a key role. In this sense, the study of optimal operation strategies for such systems becomes highly important. Thus, the purpose of this work will be to investigate using the Nondominated Sorting Genetic Algorithm II (NSGA II) the operation of a 4 gas microturbine...
Our paper presents some procedures to optimize the performances of the two magnetically coupled coils used in the Wireless Power Transfer (WPT). The optimization of the two magnetically coupled coils is performed in function of their parameter values, for different structures, orientations, positions, and turn number of the two coils. Using the ANSYS Extractor Q3D Program the C, L, R, and G matrices,...
