“…Therefore, the matrix converter has two more degrees of freedom than the voltage source inverter, which is used to control other parameters of the machine such as power factor and line current THD, therefore, reducing high flux and torque ripples. According to the above statement, a switching table is provided for the direct torque control of the five-phase PMSM, which can be seen as a part of the block diagram of the DTC method using a matrix converter, as shown in Figure 6 [16].…”

Five-phase permanent magnet synchronous motors (PMSM) have special applications in which highly accurate speed and torque control of the motor are a strong requirement. Direct Torque Control (DTC) is a suitable method for the driver structure of these motors. If in this method, instead of using a common five-phase voltage source inverter, a three-phase to five-phase matrix converter is used, the low-frequency current harmonics and the high torque ripple are limited, and an improved input power factor is obtained. Because the input voltages of such converters are directly supplied by input three-phase supply voltages, an imbalance in the voltages will cause problems such as unbalanced stator currents and electromagnetic torque fluctuations. In this paper, a new method is introduced to remove speed and torque oscillator factors. For this purpose, motor torque equations were developed and the oscillation components created by the unbalanced source voltage, determined. Then, using the active and reactive power reference generator, the controller power reference was adjusted in such a way that the electromagnetic torque of the motor did not change. By this means, a number of features including speed, torque, and flux of the motor were improved in terms of the above-mentioned conditions. Simulations were analyzed using Matlab/Simulink software.

“…Liang and co-workers (2016) proposed an analytical method of calculating the inductance of the d and q axles for internal permanent magnet (IPM) motors with V-shaped rotors in no-load conditions. The utility is to improve the efficiency of internal permanent magnet (IPM) motors used in an electric vehicle [85]. The proposed method was verified with a 48-slot/8-pole IPM motor with a V-shaped rotor.…”

Energy efficiency and management is certainly one of the key drivers of human progress. Thus, the trends in the energy research are a topic of interest for the scientific community. The aim of this study is to highlight global research trends in this field through the analysis of a scientific journal indexed exclusively in the energy and fuels category. For this purpose, a journal has been selected that is in the center of the category considering its impact factor, which is only indexed in this category and of open access, Energies of the publisher MDPI. Therefore, a bibliometric analysis of all the contents of the journal between 2008 and 2020, 13,740 documents published, has been carried out. Analyzing the articles that are linked to each other by their citations, 14 clusters or research topics have been detected: smart grids; climate change–electric energy community; energy storage; bioenergy sources; prediction algorithms applied to power; optimization of the grid link for renewable energy; wind power; sustainability of power systems; hydrocarbon improvements; conversion of thermal/electrical energy; electric motor advancements; marine renewable energy; hydropower and energy storage; and preventive techniques in power transformers. The main keywords found were electric vehicle, renewable energy, microgrid, smart grid, and energy efficiency. In short, energy research remains necessary to meet the future challenge of sustainable energy with high efficiency and the exploration of new renewable resources, all for increasingly sustainable cities.

“…In general, the V-shape topologies have high inductance resulted from the low reluctance path. However, removal of the iron ribs increase the q axis reluctance path due to the increase in the q axis airgap length [27,29], which can influence the value of the inductance. Therefore, the inductance of the VCP machine is only 2% higher than that of the IMCP machine, 16.3mH.…”

 Abstract --In low speed applications, variable reluctance permanent magnet machines are often proposed due to their efficient use of magnet material and high torque density. This becomes even more important in large linear applications, where the translator is longer than the stator. Often, however, very low power factors are experienced by this class of machine. This paper proposes a V-shape flux concentrated version of a consequent pole linear Vernier hybrid permanent magnet machine and compares it to a surface mounted magnet variant. Using finite element analysis validated by two laboratory prototypes, it is shown that the flux concentrated version increases the airgap flux density, which potentially leads to an improvement in the force density and efficiency, or can be used to increase the operating power factor.Index Terms--consequent pole, V-shape, Vernier machine, power factor, linear machine, leakage flux.
