Among various cooling methods, direct oil cooling is becoming more popular since it enables it to remove the heat directly from the heat source and subsequently improves the cooling performance. Aside from the cooling performance with direct cooling, the material compatibility of the coolant with machine components, particularly the electrical insulation system, is currently getting more attention. However, practical work regarding this issue is rare. Importantly, there still need to be widely recognised standards or instructions for compatibility evaluation. In the present work, the feasibility of conventional diagnostic approaches of insulation systems for compatibility evaluation is discussed. Particularly, a method to estimate the lifetime of the insulation system considering the compatibility issue is provided, and the role of mechanical stress during the compatibility study is analysed.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114992387","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}

Recently, hairpin windings are receiving more and more interest from both industry and academia, as they are a promising solution to achieve the above requirements altogether. However, a number of challenges still need to be addressed, including electromagnetic, thermal and manufacturing aspects. One of these is the reliability of the welding process, where the solution could be adopting continuous hairpin windings. However, these result in open slot designs or special stator arrangements, which can produce undesirable effects in motors, such as ripple torque, increased permanent magnet losses, etc. This paper aims at comparing the main electromagnetic performance metrics for a conventional hairpin winding, wound onto a benchmark stator with a semi-closed slot opening design, and a continuous hairpin winding, where the slot opening is open. Finally, the adoption of semi-magnetic slot wedges is investigated and aimed at improving overall motor performance.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128792125","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 unique feature of the axial flux design presented is that distributed windings are used in a yokeless stator, where the conductors are in slots which are fully open at both ends and are thus subject to a greater effect of flux leakage across the slots. The slot leakage inductance is predicted with the analytical model and validated using a Finite Element (FE) model in this novel arrangement. An analytical model is developed to capture the skin and proximity effects of the conductors. Also, an analytical AC copper resistance model is developed, and the results are compared with those from FE analysis.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127391750","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}

Due to the various stator phase arrangements, standard fault detection techniques are unfeasible and cannot be considered to diagnose faults in the various configurations of multiphase machines, especially those employing closed-loop control strategies and under Fault Tolerant Operating (FTO) conditions. This paper evaluates two distinctive indicators for diagnosing both inter-turn short-circuit faults (ITSCFs) and open-circuit faults (OCFs), resorting to the Short Time Least Square Prony's algorithm (STLSP). The indicators are employed in an asymmetrical six-phase induction motor (ASPIM), controlled by a model predictive control (MPC) algorithm. MPC is selected since it offers an attractive control scheme for the regulation of multiphase electric drives, exploiting their inherent advantages. A variety of operating scenarios confirm the excellent generalization capability of the proposed indicators, high accuracy and robustness, along with the ability to distinguish between the occurrence of motor ITSCFs and converter faults (OCFs), under FTO conditions.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126203838","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}

Many methods have been proposed and commercialized in industrial applications such as fans, pumps and home appliances. In case of electric vehicle (EV) traction application encoder is normally used, hence sensorless control provides back-up in case of encoder failure. The aim of the paper is to provide an overview of sensorless control methods used or likely to be used on EV traction motors. Overall, EV motors have high power density and can operate under heavy saturation, thus not every sensorless method is suitable, and operating range is likely to be limited in sensorless mode. Our goal is to identify which sensorless control techniques are more suitable to be embedded in the control of EV traction motor.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116215056","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 main advantages over their rare earth permanent magnet counterpart are the ease of control, the inherent fault tolerance, the low cost, the use of more sustainable materials, etc. However, permanent magnet machines are well known to provide higher power density and efficiency values, which make them the usually preferred choice as generator on board of aircraft. This is also enabled by the more robust structure of the rotor which allows operations at relatively high speeds. Contrarily, the rotor of the wound-field machine comprises salient poles, making it unsuitable for high-speed operations. This paper aims at investigating the structural and thermal performance of a high-speed wound-field generator for aircraft applications. The electromagnetic aspects, extensively dealt with in a previous publication of the authors, are not discussed in this paper. On the other hand, 2D and 3D finite-element structural analyses, as well as computational fluid dynamics evaluations, are carried out. From a structural point of view, the centrifugal forces acting on the end windings were managed by adding a layer of non-magnetic material at the periphery of the rotor. From a thermal point of view, removing the rotor cage previously designed as a retaining system allowed the enabled axial flow to cool down the rotor. The results revealed the designed motor to be suitable for the application at hand.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126922377","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}

Especially for efficient electrical drives, that are produced in large volumes, it becomes necessary to know, how build in components like electrical steel stacks of stator and rotor perform. For the latter, their magnetic behavior is primarily responsible for an electric drive’s overall performance. Hence, a magnetic measurement device has been designed and built to further investigate net shape parts regarding production-related magnetic property variations. Within this paper, a detailed insight in the design of a net shape part measuring setup for segmented stator teeth is given. The measurement system is validated concerning its ability to perform repeatable measurements of the same part geometry. The small measurement deviation allows to further investigate variations in testing conditions like the applied mounting pressure. To give an outlook on the future field of application of such measurement systems in large volume production lines, an investigation of parts produced from different batches indicates the range in which magnetic properties of final parts vary.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"767 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132971344","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 ensuing additional losses are evaluated and a fast methodology for the conductor sizing is illustrated. Subsequently, after evaluating the harmonic content of the current feeding the electric motor, estimated considering a standardized highway driving cycle, the losses are assessed using analytical and finite element methods (FEM) and then compared with an HW layout taken as benchmark.

The paper demonstrates how to scale the motor and converter size up or down to cover a wide range of lifting system applications. The turns versus length design plane is employed to select the correct number of turns and minimize the stack length of the scaled machine at the same time.
