Thanks to the six-step operation of the BLDC motors, current waveform can be precisely represented by its extrema without loss of too much information, resulting in more computational benefits and less required memory. Effect of PM demagnetization on these extrema analytically investigated here. In addition to the extrema features, autoregressive coefficients and K-means distances are used as auxiliary features. Then, these patterns are utilized for classification of windowed current time-series in order to detect PM defects in the machine. Each window of the current waveform is classified; then final decision is based on majority voting between the decisions for each segment. Segmentation along with majority voting makes this fault detection scheme more robust to noise and external disturbances such as load oscillations due to required short-time for capturing waveforms.","PeriodicalId":325413,"journal":{"name":"2017 IEEE 11th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133047604","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}

A new time-domain signal processing algorithm using second order generalized integrator-adaptive notch filter (SOGI-ANF) is introduced for online extraction of both steady state and transient envelopes. The adaptive nature and the structural simplicity of the SOGI-ANF as well as its low cost and low computation burden characteristics make it highly suitable for hardware implementation using embedded devices. The superiority of the SOGI-ANF over traditional Hilbert transform-based methods is its adaptive nature which allows accurate tracking of envelope variations. The analytical basis of the proposed method and its experimental verification using a STM32F4 discovery board are investigated. Finite element method (FEM) and experimental setup in the laboratory are also employed to demonstrate the adaptivity and performance of the SOGI-ANF in extracting the steady state and transient phase current envelopes.","PeriodicalId":325413,"journal":{"name":"2017 IEEE 11th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123577466","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}

To this aim, this paper analyzes and summarizes the deterioration depths presented in the literature.

Electric vehicles, supplied by energy from charging when standing still, have significantly more limited operating range than vehicles supplied by combustible fuels. Electric road systems allow the electric vehicles to charge continuously while driving, making the electric vehicles range longer than for conventional vehicles, essentially infinite. With multiple vehicles charging from the same electric road system the combined power transfer is high. An ERS system located on the ground can be reached and touched by humans and animals. Thus, apart from the electric safety issue, the operating temperature of the ERS system is also a safety issue. This makes it important to investigate the different sources of heat to understand where improvements can be made.","PeriodicalId":325413,"journal":{"name":"2017 IEEE 11th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114760594","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}

Especially, the electrical insulation is one of the most vulnerable components of an ac machine. Fast switching of the inverter results in high output voltage slew rates increasing the stress on the insulation as well as the rate of deterioration. The described stator insulation monitoring technique detects imminent deviations from a healthy stator insulation state by evaluation of the current response induced by inverter switching. Effects occurring during the aging of the insulation, e.g. changes of electrical parasitic components, lead to deviations in the transient current oscillation. Since the degradation of the insulation is usually a slowly developing process, the observation of the insulation condition is possible during operation and when the drive is put into service and continuing over the whole lifetime. The target of the approach is to detect the insulation degradation in an incipient stage. In order to operate the monitoring system economically, conventional current transducers typically used in industrial applications are used. Experimental results of a 1.4 MW induction machine for railway applications, fed by inverters with different semiconductor technologies (IGBT, SiC-MOSFET) are presented.","PeriodicalId":325413,"journal":{"name":"2017 IEEE 11th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123971616","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}
