Therefore the use of a broadband signal is proposed instead of the excitation of only one frequency in the test signal and this sequentially for different signal frequencies. Furthermore, the test signals are often generated by using a waveform generator externally applied to the machine, which is not commonly available in the field. In this paper the generation of broadband test signals by using a voltage-source inverter (VSI) resulting in a multisine SSFR test is discussed. Using this multisine SSFR test the influence of saturation and cross-saturation on the q- and d-axis parameters can be swiftly evaluated.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133376689","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 focuses principally on the transformer leakage inductances computation. First, the implemented analytical model is presented. It takes into account nonlinear elements behaviors, such as transformers, as well as other elements that behavior is both discontinuous and nonlinear, such as static electronic switch. Then, the analytical model is completed by a numerical one based on finite elements calculation. The obtained combined model enables computing separately the transformer primary and secondary leakage inductances. The implementation of the hybrid analytical-numerical methodology highlights the complementarity of these two approaches and improves the reliability of ldquothe transformer calculationsrdquo.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115559281","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 contact resistance values are compared to full load stray loss values determined using the IEEE input-output method. The stray losses generally decrease with decreasing contact resistance. This result is consistent with the general theory explained by Odok that rotor losses can peak at an intermediate value of contact resistance. For contact resistance values below the maximum loss value, decreasing the contact resistance would decrease the rotor losses. However, additional calculations and test results on skewed and non-skewed 5 hp cast aluminum cage motors are less consistent with the inter-bar loss calculations. The values of the two slot harmonic leakage reactance terms significantly impact the calculated rotor inter-bar losses.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114345157","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 the developed approach, the off-line computations of switching patterns based on harmonic elimination strategy are stored in EPROM, thereby allowing a microprocessor-free design. With the proposed configuration, the circuits for the adjustments of modulation index and phase angle are synthesized onto a field-programmable gate array (FPGA) by means of hardware description language (VHDL). Since the VHDL statements, contrary to regular microprocessor programs, are inherently concurrent, high-speed response for determination of circuit output (switching state associated with the specified modulation index and phase angle) can be achieved. Furthermore, in order to limit switching losses for high power applications, eight switching sets having switching angles from 3 to 17 (M=2N+1, N=1...8) in each quarter fundamental period are available. Experimental and simulation results are presented to verify the effectiveness and accuracy of the proposed configuration.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114770272","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 higher torque ripple from magnetic saliency is a serious problem preventing its applications from being expanded. To reduce torque ripple, we propose an instantaneous torque control method using flux-based commutation and phase-torque distribution. It provides efficient driving for SR motors with limited torque ripple. In this paper, we consider the application of this method to control torque of the SR motors for an electric vehicle (EV).","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117310912","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, most of researches are limited in LIM unit design. On a moving LIM, the change of an air-gap (it occurs by a construction tolerance of a secondary reaction plate) can lead to decrease a smoother ride and efficiency of the railway transit system. Therefore, a uniform air-gap operation of the LIM is important issue to improve the system efficiency. However, the researches about the air-gap length control of the LIM have been not advanced a lot due to a technical and high-cost problem. Therefore, in this research, the authors introduce an air-gap control system to control the air-gap length which depends on the flatness of the secondary reaction plate when the LIM is been operating. Then, through a dynamic modeling and analysis of the system, the authors analyze characteristic variations of some parameters (spring coefficient, damping coefficient, displacement, and exiting force) which compose the system, and conduct a research on feasibility of the system.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123721176","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}
