Solutions with external rotor are preferred due to necessity of minimization of the machine weight. Relatively low value of the supply voltage requires that parallel connections within each of the motor phases should be adopted. When selecting optimum pole-arcs of permanent magnets, the relevant analysis concerns not only their influence on the generated cogging torque, electromagnetic torque, and induced voltage, but also circulating currents resulting from the assumed configuration of stator windings. Waveforms of currents, voltages, and the electromagnetic torque are determined for a selected motor working point. Finally, conclusions concerning the analyzed motor are presented.","PeriodicalId":246203,"journal":{"name":"2015 International Conference on Electrical Drives and Power Electronics (EDPE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128075432","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 main goal is to present the traditional approach to mitigation of those risks, as well as to identify its disadvantages. The option to introduce technical diagnostics in the field of explosion protection presents the central part of this paper which discusses the use of technical diagnostics based on the voltage pulse response analysis and cage rotor bars conductivity measurement on induction motor as a reliable tool for detection of ignition sources. Detection of faults which cannot be identified using the traditional approach tools was analysed. Based on the research results the new approach is suggested which allows for the overall and reliable assessment of the explosion protection properties of the motor during its longtime service. Recognition of the need to timely identify induction motor faults in electrical drives, as potential sources of ignition of explosive atmosphere, is the essential conclusion and contribution of this research.","PeriodicalId":246203,"journal":{"name":"2015 International Conference on Electrical Drives and Power Electronics (EDPE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131670128","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}
