The input of this model is the discharge capacity of a particular instance of a lithium-ion battery and a constant discharge current at which the discharge capacity is determined. The output of the model is determined by the discharge capacity of the considered instance of the lithium-ion battery. The model under consideration for the discharge capacities of a lithium-ion battery is obtained by excluding dynamic variables and unknown constant coefficients from the system of physical and chemical processes in lithium-ion battery equations. This exclusion of dynamic variables is carried out numerically by calculating different dynamics of physical and chemical processes in a lithium-ion battery corresponding to different values of constant coefficients and further approximation of the desired model on these calculated dynamics. The obtained model is tested experimentally.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126831643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A special effect from the use of high-torque permanent magnet synchronous electric motors can be achieved in the aerospace industry as electric motors for various executive units, for example, a flaps drive, slats or elevators. One of the main problems in high-torque permanent magnet synchronous electric motors design is hysteresis and eddy currents losses. To minimize hysteresis and eddy current losses it is possible to use amorphous low-coercivity materials in high-torque permanent magnet synchronous electric motors magnetic cores. To assess the effectiveness of using amorphous low-coercivity materials, comparisons are made of high-torque permanent magnet synchronous electric motors with a magnetic core made from amorphous low-coercivity materials with a similar high-torque permanent magnet synchronous electric motors, whose magnetic core is made of electrotechnical steel. A multi-polar high-torque permanent magnet synchronous electric motors with a fractional toothed winding is considered. The studies results show the possibility of creating high-torque permanent magnet synchronous electric motors with magnetic cores from amorphous low-coercivity materials and the effectiveness of using amorphous low-coercivity materials in high-torque permanent magnet synchronous electric motors has been proven.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133452334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formula for calculating the power emitted by the active component of the leakage current is obtained. The basic mathematical model of thermal processes of a power cable line was refined by taking into account the values of internal heat sources. A mathematical model was obtained that allows calculating the power of partial discharges, as well as determining the location of the inclusion in the main insulation, due to the power of the active component of the leakage current, when it occurs in the main cable insulation. The calculation of the change in heat flux passing through the layers of cable insulation by the piecewise-specified functions method, taking into account the thermal resistance of the inclusion, is carried out. The mathematical model, along with the layer-by-layer calculation of isotherms in the cable section, makes it possible to determine the presence of inclusions in the insulating material and their influence on the temperature distribution profile at characteristic points of the cable section. The method proposed in the developed model makes it possible to account for heat losses based on the thermal and geometric dimensions of the inclusion. This will allow to obtain the temperature in all layers of the cable line, starting from the radial distances, inclusion parameters caused by the insulation core current, as the main temperature-forming factor.","PeriodicalId":371743,"journal":{"name":"2019 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127797628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, analytical formulas were derived that allow calculating the parameters of the electromagnetic field and integral values depending on the axial coordinate and radius with a simultaneous analytical solution of a two-dimensional electromagnetic field for areas of the radius of the system from the axis of the inductor or detail to the internal radius of the inductor. The dependences obtained on the basis of the equation for the vector potential and the Bessel equations of zero and first order, which determine the influence of the geometric parameters of the inductor and the details on the magnetic field strength and specific power, are given. Cases of cylindrical coils with a specified number of turns, as well as coils in the form of thin or flat rings are considered.
