In the model, Maxwell's Equations are solved for the hysteresis character in the magnetic lamination, using the Galerkin finite element method, where the hysteresis is represented by an energetic hysteresis model. Based on the simulation results, the magnetic characteristics, skin effect, time delay and magnetic field distribution are discussed. Then core losses, especially excess losses, affected by the magnetic characteristics are carefully examined. It is concluded that excess current losses are due to the non-uniform magnetic field distribution resulting from the skin effect and the non-linear diffusion of magnetic flux from the boundary to the inside of the lamination.","PeriodicalId":178685,"journal":{"name":"2009 IEEE Industry Applications Society Annual Meeting","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122220211","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 has been observed at a brushless dc (BLDC) compressor motor manufacturing facility that improper magnetization of the rotor permanent magnet is one of the leading causes of motor defects. A new technique for postmanufacturing assessment of the magnetization quality of concentrated winding BLDC compressor motors for QA is proposed in this paper. The new method evaluates the data acquired during the test runs performed after motor assembly to observe anomalies in the zero-crossing pattern of the back-EMF voltages for screening motor units with defective magnetization. An experimental study on healthy and defective 250-W BLDC compressor motor units shows that the proposed technique provides sensitive detection of magnetization defects that existing tests were not capable of finding. The proposed algorithm does not require additional hardware for implementation since it can be added to the existing test-run inverter of the QA system as a software algorithm.","PeriodicalId":178685,"journal":{"name":"2009 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131533601","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 resulting model removes the high- frequency component while keeping the useful information contained in the waveform envelopes. The method provides large and small-signal Spice compatible models in a straightforward manner. The inverter is controlled at constant switching frequency by the phase displacement, Ψ, of the midpoint voltage of one class D section referred to the others. An approximated explicit form of the small-signal transfer function from the control angle, Ψ, to the load current is obtained by using a reduced order model. The proposed overlap phase control exhibits a wide bandwidth suitable for applications such as control of gaseous discharges. Experimental results are given using a 400W high-pressure sodium lamp as load.","PeriodicalId":178685,"journal":{"name":"2009 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126312938","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}

With this method, power closed loop can be easily realized and protection can also be carried out correctly when malfunctions including open-circuit and short- circuit state occur. Experimental results show that UV-lamp ignites reliably, harmonic content can be controlled below 10% and efficiency of the ballast can be higher than 94%. Keywords-- Ballast, UV lamp, Microprocessor I. INTRODUCTION Ultraviolet (UV) lamp is more and more widely used in the fields of waste water treatment, medical treatment and so on owing to its strong bactericidal effect. The UV-lamp used here is common cold cathode UV-lamp, and it's mainly used for disinfection of air and surface of object. Because of improving processing technique, cold cathode UV-lamp has longer service life and higher radiance than hot cathode UV- lamp. The ballast studied here is used for waste water treatment. The lamp voltage of code cathode UV lamp is very high, so its lamp current is very small which makes it difficult to do power closed loop. And because the lamp is in the water, the down-lead of the lamp is usually very long which makes igniting and protecting difficult. Nowadays, different kinds of machines tend towards intellectualized. And it's not only limited to illumine the lamp for the ballast, but required to estimate the ballast's working condition to keep the ballast and the lamp safe, what is more important is to prevent industrial accident, so sixpenny 8-bit single-chip microprocessor becomes a reasonable choice. The MCU used here is MC68HC908 which is produced by Freescale and has extremely high reliability. With this kind of chip microprocessor, steady ignition, estimation of open- circuit and short-circuit state, power closed-loop control can be realized easily. The main circuit here is resonant circuit which uses the topology of LCC, but resonance point of triple-frequency harmonics is used here instead of fundamental wave, so voltage stress and current stress of passive network can be decreased a lot because the energy of triple-frequency harmonics is relatively much lower than fundamental wave. This paper also presents a kind of drive circuit which can supply unerring switching signal and adjust dead band time properly.","PeriodicalId":178685,"journal":{"name":"2009 IEEE Industry Applications Society Annual Meeting","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128875013","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}

After sintering, a three-dimensional network layer was obtained. This process will be simpler than chemical vapor deposition (CVD) method because fine particles are from powder dispersion, not prepared by CVD.

MBPR differential equation approach can tolerate some errors caused by power system abnormality such as DC offset. It is widely implemented in the protections for lines, transformers, buses, motor, and other equipment in power systems. However, the parameters for system description algorithms are obtained from power system current i(t) or voltage v(t), which are abnormal values under fault or distortion situations. So the error study for the algorithm is considered necessary.","PeriodicalId":178685,"journal":{"name":"2009 IEEE Industry Applications Society Annual Meeting","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133657150","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}
