In the search for better solutions the multipolar axial-flux PMSM and the multipolar-inner claw-pole stator PMSM evolved as major competitors very recently. In an effort to reduce computation time effort in the optimal design of the inner-claw-pole-stator PMSM for small power applications, to the end of using a single desktop competitive computer, the present paper develops a 3D-MEC (magnetic equivalent circuit model) for the case in point integrated into a dedicated MATLAB code with a unique multi-term objective function, with constraints on efficiency in 3 operation points (torque speed pairs), demagnetization avoidance at 2pu load, and the motor materials cost as the main term; all terms in USD. For a case study the output file provides numerical and graphical comprehensive data that are sufficient to approach the fabrication for four cases: round and slab copper or aluminum wire in ac coils Finally for one optimal design and main operation point key validation with 3D-FEM is offered. The computation time for one wire type with 30 runs from random starting points, on a typical desktop computer was 81.12 seconds, which is an order of magnitudes smaller than existing (arguably more precise) methods.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87533869","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}

Software developers create tools able to perform highly accurate and reliable simulations, however concentrated on types of assemblies of the entire vehicle. Attempting to simulate a full vehicle using a single software, generally leads to many difficulties and non-reliable results. Co-simulations can solve partially this problem with the cost of very long simulation times using powerful computers. The present paper offers a solution to this issue, based on an integration software (National Instruments VeriStand), running online on a real-time target (PXI computer). VeriStand can link into one real-time simulation vehicle assemblies with models created in different software packages. Even more, it is possible to run the interconnected models and at the same time to output/input quantities from real hardware. In this philosophy, the urban electric vehicle model is created in Amesim software, specialized in electrical and mechanical designs. A ultracapacitors supplied urban electrical vehicle is modelled and simulated following this approach. The vehicle is simulated offline in Amesim environment and the output data is used in a real-time simulation to test the Simulink model of the supercapacitors in parallel with the operation of the real hardware.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84122681","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}

In this paper, two different methods are used to estimate how much memory is needed to evaluate the SOC and their performances regarding tracking accuracy, memory volume and computational complexity. The SOC and SOH cannot be directly measured and estimation is influenced by many factors, such us battery aging, ambient temperature and the current rate. The complex interrelationship of these factors causes the difficulties in the pursuit of a precise SOC estimation method. The important issue of this study is to obtain the SOC estimation for a specific Li-ion battery based on the behaviour of the battery during operation. The analyzed Li-ion battery is part of a micro-grid (MG) belonging to the Advanced Electrical Systems Research Centre within the Research and Development Institute of Transilvania University of Brasov, which provides around 20 kWh storage capacity. Through simulations, the analyzed SOC estimation method is verified to demonstrate the computational complexity and accuracy.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74275712","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}

Making its right choice will ascertain the range anxiety, maximum speed and battery ratings required for the electric vehicle. The radical increase in the cost of rare earth magnet materials has pressurized all the countries to come up with rare earth magnet free motor as the traction choice. Interior permanent magnet synchronous motor (IPMSM) is the most widely used one although it suffers from the risk of demagnetization at higher temperatures. Due to the aforesaid reasons its popularity is diminishing. This scenario clearly indicates the requirement of feasibility check for Synchronous reluctance motor (SynRM) as the traction choice. This paper provides an in-depth discussion about the performance analysis of SynRM under the following heads: Peak torque capability, continuous thermal envelope, inverter rating and drive cycle analysis. Here the efficiency maps across the entire speed and torque range is studied with Worldwide Harmonized Light Vehicles Test Procedure (WLTP) Class 2 drive cycle. Thereafter these performance indies are compared with an IPMSM of comparable power rating. Another important aspect highlighted here is the tradeoff study between cost, weight and efficiency of the designed motor that will bring in a holistic picture.","PeriodicalId":32117,"journal":{"name":"Bioma","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88843625","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}
