From a topological point of view, both machines present the same armature arrangement and are equipped by a toroidal field in the stator. They differ by their second source of excitation which is achieved by a NdFeB-PM in a candidate and by ferrite-PMs in the other. Following an analysis of the flux paths through their magnetic circuits, the machines are the subject of 3D-FEA that enables the investigation of their no-load features. Then, the study is extended to the load operation with a special attention paid to the computation of the iron losses.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127259469","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}

For the fast prediction of induction motor steady-state performance without the need for time-consuming finite-element analyses, the equivalent circuit parameters of the machine need to be calculated, including rotor slot leakage inductances. This paper, in particular, proposes a new improved analytical formula to determine the rotor slot leakage inductance in squirrel-cage induction motors with rectangular-shaped bars. The formula is obtained by solving Poisson's equation in the slot domain. Results are assessed by comparison against Finite Element Analysis (FEA). The precision of the presented methodology is also compared to that of approximated analytical models available from the literature. The comparison shows that the accurate formula proposed is in excellent agreement with FEA with errors below 2%, while the simplified model generally leads to errors above 10% which increase as the height-to-width bar ratio decreases.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125016204","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 introduces a new method-matching pursuit which is applied in the denoising of current signal. The proposed method designs the optimal atom based on the similarity between original signal and atoms by using matching pursuit (MP) algorithm. The conventional MP algorithm needs large amount of calculation due to the overcomplete dictionary. To overcome this problem, this parper demonstrates the effectiveness of MP algorithm with undercomplete dictionary. The undercomplete dictionary is consist of sinusoidal atoms after analyzing the characteristic of actual current signal. The signal set partitioning method is proposed to optimize the configuration of dictionary. Simulation and experimental results verify the feasibility and efficiency of the proposed method.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128696256","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}

Both the ability to switch the electric machine's number of pole pairs and a very efficient 60-phase inverter based on MOSFETs promise a dramatic reduction of losses inside the power train. Investigations on driving cycle efficiencies are carried out for a HV reference system and the novel LV system. The New European Driving Cycle (NEDC) and the driving cycle of the Worldwide harmonized Light vehicles Test Procedures (WLTC) are virtually driven by a common vehicle model in order to determine load profiles for both traction systems. Losses in electric machine, power electronics and battery are estimated and the total vehicle's energy consumption is derived. The novel LV traction system promises a great enhancement in driving range compared to the state-of-the-art HV drive.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130197993","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}

Various attempts to predict pore pressure have been made by researchers to best describe the trend for a given region. Several methods have been published and claimed to work for many fields. This paper provides a case study for an oil field in Iran in order to check the applicability of some of the methods in this field. Eaton's, Holbrook's and Weakley's method are tried and it is found that Eaton's method provides a closer result, if not an accurate one. The details of the formation are stated to study the nature of these methods in such environment. The compaction exponent of Eaton's method is varied to see the variation in the trend for the field. The compaction exponent of 3.0 is found to work fairly well for depths up to 2600m while exponent value of 0.7 works for depth greater than 2600m. It is inferred that not all methods are applicable globally and there exists a need for further research to develop or modify these methods either qualitatively or quantitatively.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128771368","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 principle of the proposed strategy consists in keeping the voltage vector of each motor phase during 60° of the half of a cycle of the reference stator flux vector. The synthesis of the vector selection tables (one for clockwise rotation and the other for anti-clockwise rotation) is achieved on the basis that enables the fulfilment of the control combinations related to the variations of the stator flux and the electromagnetic torque, along with a reduction of their ripples. Simulation results highlight the torque high dynamic as well as reduced ripple, exhibited by the three level NPC inverter fed induction motor drive under the control of the proposed bus-clamping DTC strategy.","PeriodicalId":365573,"journal":{"name":"2015 International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117029273","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}
