Hence, this paper investigates accurate machine modeling for control and parameter estimation. In the proposed approach, the PMSM model with saturated inductances is used as the base model, and this paper investigates modeling and compensation of the offsets to the base model due to system nonlinearities such as saturation and core loss effects for accurate machine modeling and voltage prediction. Specifically, the offsets to the base model are modeled using nonlinear functions with variable coefficients to compensate saturation and core loss effect, which can achieve better accuracy without changing the model structure. A differential estimation model is derived to estimate the model coefficients from a small amount of measurements with simplified procedure. Moreover, the model offset calculation is both computation and memory efficient with simplified implementation. The contribution is to improve the machine model accuracy and achieve precise voltage prediction for practical applications. Experiments, comparisons and the application to temperature estimation are conducted on a test interior PMSM to validate the proposed approach.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 4","pages":"394-403"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10705034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In space vector PWM (SVPWM) techniques, the average realization of the space vector applying the volt-sec balance principle results in an instantaneous error voltage that generates high frequency torque ripple. It may lead to an increase in motor vibration and acoustic noise. This article presents a high frequency torque ripple prediction model based on stator flux ripple and proposes a targeted designed variable switching frequency PWM (VSFPWM) strategy to diminish high frequency torque ripple. The switching frequency is dynamically adjusted according to the peak value of the predicted stator flux ripple to mitigate high frequency torque ripple. In contrast to existing strategies, the strategy outlined in this article directly suppresses high frequency torque ripple, thus remaining unaffected by inaccurate motor parameters. Additionally, due to the introduction of the power factor angle, the proposed strategy can better adapt to the full speed range operating conditions of the motor. Detailed simulations and experiments are provided to validate the effectiveness of the proposed strategy.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 4","pages":"414-425"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10705031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Literature considers chip size, placement, coolant flow direction with the goal of reducing thermal resistance of power modules, minimizing chip junction temperature differentials, and optimizing Pinfin layouts. In the first step, algorithms should efficiently generating numerous unique irregular Pinfin layouts to enhance optimization quality. The second step is to efficiently evaluate Pinfin layouts. Simulation accuracy and speed should be ensured to improve computational efficiency. Finally, to improve overall heat dissipation effectiveness, papers establish models for capacitors, motors, to aid collaborative Pinfin optimization.

The rotor of an induction motor can be either a squirrel cage rotor or a wound-type rotor, both existing as magnetless topologies. Three-phase squirrel cage induction motors are frequently utilized in industrial drives because they are dependable, have high starting torque, are self-starting and affordable. Single-phase induction motors, on the other hand, are commonly used for small loads such as domestic appliances in form of modest fans, pumps and electric power tools. In South Africa, there have been reports of fires and explosions resulting in live and property loss because of induction motors that have not been thoroughly tested or are incorrectly labelled in terms of ratings, electrical safety and performance. The goal of this study is targeted at preventing end-user injuries and failures caused by non-compliant induction motors, by evaluating locally manufactured/imported induction motors based on tests and evaluation from standards (IEC and SANS). The study is conducted using experimental procedures at the Explosion Prevention Technology and Rotating Machines (EPT and RM) laboratory, South African Bureau of Standards (SABS), South Africa. The main finding from the study shows differences in the nameplate characteristics of various induction motors which could have detrimental effects such as production and operational downtime in their end-use industries, at later stages.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 3","pages":"310-318"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10702521","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, fractional slot concentrated windings (FSCW) are well known because of short end winding length, simple structure, field weakening sufficiency, fault tolerant capability and higher slot fill factor. The five-phase machines equipped with FSCW, are very good candidates for the purpose of designing motors for high reliable applications, like electric cars, major transporting buses, high speed trains and massive trucks. But, in comparison to the general distributed windings, the FSCWs contain high magnetomotive force (MMF) space harmonic contents, which cause unwanted effects on the machine ability, such as localized iron saturation and core losses. This manuscript introduces several new five-phase fractional slot winding layouts, by the means of slot shifting concept in order to design the new types of synchronous reluctance motors (SynRels). In order to examine the proposed winding's performances, three sample machines are designed as case studies, and analytical study and finite element analysis (FEA) is used for validation.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 3","pages":"264-273"},"PeriodicalIF":0.0,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10640368","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
