We derive mathematical models that consider magnetic saturation, and use this model for position estimation. The proposed method requires neither any band-pass filters nor motor parameters, and it can be applied to all kinds of synchronous motors without any tuning. Polarity detection of the magnetic pole can be also determined simultaneously with position estimation, making extra signals for polarity detection unnecessary. The proposed estimation method is verified experimentally.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129034660","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 unique configuration makes the output power higher than longitudinal motors, but also it makes characteristic analyses difficult. This paper deals with an effective analysis of a PM type TFLM by coupling 2-dimensionaI finite element method (2D FEM) on 3D equivalent magnetic circuit network method (EMCN). 2D analysis by FEM is used to find so-called multipleratio, which is multiplied by 3D analysis results, and 3D EMCN is employed in magnetic field analysis to get the static thrust and parameters for system assessment such as flux linkage, coenergy, apparent inductance, and incremental inductance. The calculated results are verified by comparison with measurements.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130813741","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 consequence becomes more severe when the disturbance input is time-correlated, hence non-white. Run out table (ROT) cooling is a complex multistage process with inherent long time delay. This intrinsic characteristic of such extensive time lag, which triggers time-correlation, makes the run out table cooling process attractive to investigate stochastic optimization methods for tracking the temperature trajectory along its stages. The merit of this approach is demonstrated by simulation experiments. The results show the state propagation and robust tracking performance in the presence of stochastic time-correlated disturbance inputs.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128187466","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 materials used to conduct the study were an electrophotographic toner, glass microspheres, and aluminum oxide powder (Al/sub 2/O/sub 3/). These materials were transported pneumatically through the tube under investigation. Voltages induced on the pipe by the flow of charges were recorded with an electrostatic voltmeter (ESVM). A total charge of each powder was measured before and after it passed through the pipe. The ESVM was measuring the voltage induced by charges carried by the flux of solid particles and by the charges generated on the tube. Author was looking for a correlation between the initial and final charge of the toner and the ESVM voltage. As a result, method of flowing charges measurement with the ESVM is proposed.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133922713","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}

No complex algorithm is required to estimate the controlled current because of the on-board peripherals of the microcontroller.

An additional advantage of using the metallic pipes is that they may lead to a substantial reduction of a magnetic field. We will examine this issue in This work as well. A numerical example involving a high voltage cable located in a cooling pipe is presented to show the effect of the natural and forced convection in the pipe on the ampacity of the cable circuit. In this practical example, the ampacity of the cable can be increased considerably, even for great cooling section lengths.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122919152","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}
