The target is the evaluation of the contribution of both the chosen PWM and ELMT strategies on the total losses of the drive. To this aim, a complete dynamic model of the drive system has been developed and implemented in Matlab-Simulink environment permitting efficiency to be evaluated in numerical simulation, properly suitably separating each loss term. Experimental results show that the integrated use of D-PWM and ELMT permits a reduction of the overall power loss up to 6% of the induction machine rated power at low load torques. Correspondingly, the drive efficiency can be increased up to about 30% at low loads and up to about 5% at high loads.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"22 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":"125178929","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 design procedure of the machine is discussed, with modeling and simulation results. Thanks to the super high speed, the designed motor can achieve high energy density at 2.5 kW/kg(housing weight included) and efficiency is over 97%. The super high speed brings challenges on electrical, mechanical and thermal design. Proper design of the stator lamination, including bore diameter, outer diameter, slot, yoke thickness and airgap is explained. At high frequency, proximity effect and skin effect becomes significant, the effects have been analyzed and multi-strand Litz wires are chosen for this design. Double-layer distributed winding is used instead of concentric winding to reduce the harmonic EMF. The rotor structure is designed to endure the mechanical stress at high RPM. Thermal analysis is conducted, and a housing with water cooling is designed. The design is optimized in ANSYS Maxwell and simulation results verified the performance of the motor. A controller for the high speed drive has been developed for the motor.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"21 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":"120962656","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}

Some keys to achieve high torque density, high efficiency, enhanced output, but reduced rms current have been presented. Comparison of efficiency distribution with respect to PM motor is presented. A similar competitive switched reluctance generator with respect to rare-earth PM generator has been investigated. It is found that switched reluctance motor is better, if idling iron loss is considered in operation. Two methods to reduce the acoustic noise are presented. One is to have cylindrical rotor outer shape to reduce windage noise. Another is novel current waveform to make radial force sum constant.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"24 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":"116444253","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}

Although commercial EVs are still to be equipped with integrated chargers, a multitude of topologies have been proposed for integration. Therefore, the need for classification arises. This paper aims to give an overview of topologies based on functionality of their integrated components. Moreover, it attempts to provide an extensive analysis of their operating principles. All the topologies are classified into three major groups. At first, topologies in which only the converter is integrated are considered. This is followed by configurations based on switched reluctance machines (SRM) in which both the converter and the machine are integrated. At last, the integration of both converter and induction machine (IM) or permanent magnet machine (PM) is elaborated within the third group. Here an example of obtained experimental results is also given. Finally, a short quantitative comparison of the topologies is provided in a table format.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"16 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":"126553582","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 we study the effect of variability in these characteristics on the operation quantities of a low speed permanent magnet wind generator. The variability itself can emerge as the result of misuse of the generator or as the consequences of the manufacturing process, which makes the characteristics different from the nominal ones. The investigations are carried out with transient finite element analysis. The results show that the most affected quantities are the power factor and the copper losses. The iron losses are slightly affected too. All these effects are shown to be the consequence of the change in the air gap flux density, which is one of the most important design parameter of the machine.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"193 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":"132696452","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, several attempts have been performed for the detection of gear tooth localized faults using induction machine electrical signature analysis with promising results. These previous researches were mainly relied on the study of mechanical impacts effects, generated by gear localized faults, on the mechanical torque and consequently on the stator phase currents. This paper aims to investigate these recent advances with particular focus on the induction machine-based drive systems. Both analytical and modeling approaches will be considered which are helpful for a better understanding of observed phenomena and which leads to identifying both reliability and effectiveness of non-invasive methods for gear tooth localized fault detection.","PeriodicalId":173358,"journal":{"name":"2015 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"13 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":"115400262","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}
