The maximum torque at a certain slip value was achieved at the number of 25 rotor slots.

The optimization of its sizes is led with the following objectives: the active mass and the global life cycle energy cost. We first compare optimization's results to those with \"classic\" mass versus power losses (copper and iron losses) optimization for several times of use ratio. This leads to recognition of the significant impact of the life cycle energy on the arrangement of the optimal Pareto fronts, explained by conflicting energy contribution in the life cycle global energy cost objective. Then we logically observe that the life cycle assessment impact is more significant when the real use duration is smaller than the lifetime. After that, the sensitivity of the optimization's results to the elementary raw materials energy costs is considered with the same times of use ratio. At last, some optimizations are run with a different raw material: aluminium instead of copper for the windings.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121120984","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}

A common characteristic among conventional control methods is that they seek to keep the flux amplitude constant so that the induction machine has control characteristics similar to those of a dc machine. In this paper, a vector control scheme based torque angle is discussed. It is shown that by keeping the torque angle constant or regulating it in an appropriate manner, dynamic performance similar to those of traditional fixed-flux-level vector control methods can be achieved with lower energy consumption and simpler operation. Objectives such as maximum efficiency, maximum power factor, or maximum torque per amp can be achieved readily in steady state under this control.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121318069","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 spite of the several advantages, these machines exhibit high contents of space harmonics in the air-gap MMF distribution, whose amplitude depends on the particular combination of number of slots and poles of the machine. The main cause of such harmonic contents is the induced losses in the rotor. The aim of this paper is to link the rotor losses to the combination of slots and poles of the PM machine. The effort is to determine a general rule to single out easily if a machine topology is suitable or not, as far as the rotor losses are concerned.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121138745","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 physical coupling between the two sets of windings was used to satisfy the application requirements. Analytical and finite element (FE) analysis of the actuator and its various improvements will be presented in this work. A dynamic model of the dual winding exterior rotor PM actuator will also be developed.

This paper introduces a new configuration for a switched reluctance motor with field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), where each stator set includes twelve salient poles with windings wrapped around them, while the rotor comprises of eight salient poles. There are different ways of connecting the motor phase windings in order to run the unit in the motor mode. The first scheme is to connect the two sets independently in series or in parallel. In this method the poles in each layer can have both north and south poles configurations. The second method is to connect the windings in each layer such that all the poles in that set have either north or south pole configuration or the poles in the other set (layer) have the opposite configuration. In this format, the magnetic field passes through a guide to the rotor then the stator and finally completes its path via the motor/ generator housing. This type of connection is also utilized in the generator mode. To evaluate the motor performance, two types of analysis, namely, the numerical technique and the experimental study have been utilized. In the numerical analysis, the finite element analysis is employed, where as in the experimental study, a proto-type motor has been built and tested. The calculated results compare favorably with the experimental test results.","PeriodicalId":446844,"journal":{"name":"2007 IEEE International Electric Machines & Drives Conference","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121457158","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}
