The author briefly traces historical trends and developments in an effort to determine the needs of the industry today. The electrical evolution of feedback tachometer generators from inaccurate analog devices to precise digital devices has improved drive system accuracy and stability. Changes have also occurred in the mechanical configurations to improve reliability. The latest trend is toward higher resolution of up to 2048 pulses per revolution and mechanical designs that eliminate failure prone components. Six case histories are included that show how today's designs solve problems, improve performance, and increase reliability. Included in these case histories are modular designs and shaft mounted designs.<<ETX>>","PeriodicalId":129476,"journal":{"name":"Conference Record of 1993 Annual Pulp and Paper Industry Technical Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131708191","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}

Today many engineers accept the premise that LCI motors belong in a category unto themselves, different from 'standard' synchronous motors. Some points of view bearing upon this theme are discussed. Operating principles, application methodologies and criteria, machine design, and field experience are reviewed. Some concepts of standard motor design are described and compared to corresponding aspects of LCI motor designs.<<ETX>>","PeriodicalId":129476,"journal":{"name":"Conference Record of 1993 Annual Pulp and Paper Industry Technical Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129230506","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}

This is due in part to improved stator and rotor construction, which may result in the bearings being the weak link. Also many bearings are being operated at increased loads, temperatures, and speeds. The environment is another major factor affecting bearing life. All too often the failed bearing is replaced without proper identification of the root cause of the failure. Hence, proper corrective actions may not be taken to minimize or avoid future failures, and extend bearing life. A methodology for identifying the cause of failure for antifriction bearings used in electric motors using antifriction bearings is presented.<<ETX>>","PeriodicalId":129476,"journal":{"name":"Conference Record of 1993 Annual Pulp and Paper Industry Technical Conference","volume":"18 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120992676","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}

Unit substations are being expanded in order to meet the demands of an expanding electrical distribution system. The electrical system requirements in many pulp and paper mills are being enlarged with greater kVA capacity transformers. Consequently, the available RMS symmetrical fault currents are likely to be in excess of the original bus bracing rating for the LVMCC. A reliable and cost-effective means of upgrading bus bracing in LVMCCs is discussed.<<ETX>>","PeriodicalId":129476,"journal":{"name":"Conference Record of 1993 Annual Pulp and Paper Industry Technical Conference","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121282734","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}
