The adopted tool is based on FE and computes the complete machines' characteristic analytically without any further FE computation. For the initial analysis and model verification a 16-pole 24-slot Interior Permanent Magnet (IPM) is adopted. The results obtained, compared to completely FE-based solution show that the proposed tool predicts the electromagnetic losses effectively within less computation time.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123217948","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 drawbacks of such setups, are the deficiency of the drive system, its high cost and the maintenance needs. An alternative to this, is the replacement of the induction motor and its mechanical transmission elements with a permanent magnet (PM) synchronous motor (PMSM) directly coupled to the load running at low speed. In this context, the paper deals with the design evaluation of a 5kW 50rpm motor and concentrates on two radial flux promising topologies i.e. with surface-mounted permanent magnets with inner and outer rotor. Since the goal is mainly the minimization of the machine's active weight (with respect to constraints related to outer dimensions, efficiency and cost), the designs of the PM machines are conducted by solving an optimization problem. Three optimization methods are adopted and three weighted cost functions are presented. The effectiveness of the methods in finding competitive alternative PMSM designs is then evaluated. The presented results are compared with other found in literature and reveal satisfactorily enhanced design solutions and performance of the proposed methods.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123720630","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}

It provides vehicles “stop and go” function, as well as power generation like an alternator. A 12 slot - 10 pole excited synchronous machine (ESM) is designed and analyzed via JMAG in this work. The ISG is required to have a high starting torque (43 Nm) and a high speed range (~18000 rpm). Apart from Nd-free advantage, a ESM has a freedom of controlling the field current: Thereby it is not necessary to apply a high negative d-axis current at a high speed, reducing thermal load. In this design, an optimum split ratio is investigated over copper and iron losses. It is also found a proper field current capable of producing a rated power satisfying the voltage limit at a maximum speed.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127683998","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}

This paper illustrates the technical implications of implementing Motor Current Signature Analysis (MCSA) as a tool for condition monitoring. The majority of machine failures are illustrated and are related to the state-of-the-art of MCSA. Because MCSA has become a valuable tool within the broader scope of condition monitoring during the last decade, a vast amount of new research opportunities can be presented. One of these opportunities is to determine Frequency Response Functions (FRFs) between the rotor vibrations and the stator current as a function of the operating point of the machine. This allows to estimate the mechanical machine fault vibrations out of the stator current frequency components, independently of its speed and load. This paper ends by presenting a research strategy to obtain this goal.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126398719","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}

Sensorless control of SynRMs is now desired, and several methods have been proposed. These methods, however, have difficulties at low speed when the voltage signal necessary to estimate rotor position is very small. This paper proposes a new rotor position estimation method using both a high-frequency extended e.m.f.(EEMF) disturbance observer and a heterodyne detection. In this paper, it is shown, experimentally, that it is possible to control the SynRMs at low speeds and under loaded conditions without the position and velocity sensor using the new proposed method.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125846008","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}

These effects are related to asymmetries in the inductor structure with respect to the rotating counterpart, in both the longitudinal and in the transversal direction. This paper propose a technique for the compensation of the LIM static end effects by a synchronous controller in conjunction with a neural adaptive filter, exploited to extract the inverse sequence current component from the inductor current signature. This permits to compensate the static-end effects and thus to cover the static asymmetries of the LIM with respect to the rotating induction motor (RIM).","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"332 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115878210","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}

Fuel Cells technology is considered to be a promising solution for on board power generation. However, FCs require auxiliary sources, such as Batteries and/or Ultracapacitors, in order to deal with the issue of fast load dynamics. Within that context, Energy Management Strategy is defined as a critical component of Hybrid Electric Vehicle, since it is responsible for energy sharing among the different sources. In this paper, a novel Energy Management Strategy is proposed that aims on current sharing between primary and auxiliary sources. This strategy is deployed in two stages through a set of rate limiter and a Fuzzy Logic Controller. The first stage defines the low harmonic component of current load demand and assigns it to FC, while the second determines which harmonic component of current load demand Ultracapacitor should cover. That procedure takes considerably into consideration energy stored in ancillary sources as well as load demands. Simulation results validate the efficiency of the proposed Energy Management Strategy.","PeriodicalId":288960,"journal":{"name":"2014 International Conference on Electrical Machines (ICEM)","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132403050","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}
