The dominant parameter in the constant power speed region is called the characteristic current which equals the ratio of the magnet flux linkage over the synchronous inductance (-ψm/Ls). Several machine parameters is affecting the characteristic current including the machine geometry and the winding configurations. In this paper, the effect of many of these parameters on the FW has been discussed; including the outer diameter, inner to outer diameter ratio, magnet size, slot opening width, slots per poles combinations,and the multi phase configurations for the Axial flux permanent magnet synchronous machine (PMSM). Two main governors are considered to evaluate the parameters' impact on the machine overall performance; the rated machine efficiency and the torque to weight ratio at the highest values. Selection of these governors is application driven where these governors are the most influencing factors on the axial flux PMSM design. The results of the present analysis show that the fine tuning of the discussed machine parameters would derive the motor to work in the required Constant Power Speed Region (CPSR) keeping the required high efficiency and torque to weight ratio. A previously proved analytical model has been used in this study to overcome the highly time consumption in the finite element model (FEM).","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125076153","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 particular, a high consideration has steered towards electrical machines as one of the most critical components, due to their primary role in energy consumption. Consequently, local and international standards, setting Minimum Efficiency Performance Requirements (MEPS), today are pushing new products beyond actual efficiency levels. This trend, in turn, is leading manufacturers to investigate all technological strategies that can offer performant and environmental-safe solutions. The scope of this work is to provide an overview on the actual regulations and technologies available on the market for high-efficiency purposes. In particular, PM-assisted synchronous reluctance motors are proposed as a sustainable solution for either fixed or variable speed applications. Comparisons among technologies are presented, together with an environmental analysis of the impact that new technologies can have within the future industrial world.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124124759","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}

Utilizing dynamic programming method, a cost function is minimized in order to identify optimum sequence of inverter switching operations for the whole prediction horizon at every sampling instant. The proposed optimal control strategy significantly reduces the inverter switching frequency while the stator flux and electromagnetic torque follow their reference values with much less ripple. Simulation is done on accurate model of inverter fed induction machine and the results confirm the superior performance of the introduced optimal control strategy compared to direct torque control and direct self-control strategies. Furthermore, due to short calculation time needed for this method, it is applicable for online control of inverter fed induction machine. The method is a general approach which can be applied on different types of electrical drives and adapted towards different distinct applications.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"24 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131452037","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}

Despite the advantages of matrix converters compared to conventional back-to-back converters, the application of these converters for synchronous reluctance motors (SyRMs) is not reported in the literature. The flux linkage on d axis and the current on q axis are closed loop controlled for the sake of a good combination of dynamic response and efficiency. Real-time maximum torque per Ampere usefully minimizes losses at all speeds, in particular at partial load. The input and output vectors of the converter are modulated using indirect space vector modulation technique. A flux observer provides the feedback to the d regulator. The nonlinearities of the converter are identified and compensated, to the benefit of voltage estimation and then flux estimation accuracy. Simulation results show that the presented MC-SyRM drive is promising for compactness and efficiency in critical applications.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128743983","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}

However, the price of rare-earth magnets has become a serious concern. The goal of this study is to compare the torque capability and electromagnetic performance of PM machines of different sizes. Generally, smaller size is a profound advantage, but may constitute a deficiency from the thermal point of view by contributing to a higher loss density, which makes the cooling of the machine more problematic. Therefore, to overcome this problem, this paper also predicts the temperature and heat transfer exposure of PM machines by proposing a thermal modeling method using suitable coolant. This paper finally determines the most suitable size of a smaller PM machine in order to reduce the usage of rare-earth magnets and other materials but which still maintains the output performance of the reference PM machine.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114249497","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 analysis of these variables in the frequency domain examines the characteristic harmonics of this fault, already known in the literature. The experimental tests have been carried out on an induction motor which allows to simulate different percentages of short circuit in one phase of its stator winding. The diagnostic information provided by the three variables are consistent among them and with respect to previous researches. The custom probe stands out for its most significant diagnostic content and its low cost, therefore it can be considered as the best candidate for applications in industrial environments.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123830193","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 results show that by maximising drive system efficiency, the motor's power factor is automatically improved to reduce inverter losses.
