Two types of induction motors are analyzed; a 2-pole pairs, star connected and an 1-pole pair, delta connected motor. The radial electromagnetic stress distribution along the airgap is calculated and developed into double Fourier series in space and time. The computations show the existence of low frequency and low order stress distributions acting on the stator of the electrical machine when it is working under faulty conditions. These stress waves are able to produce forced vibration in the stator surface. The simulation results are corroborated by vibration measurements. Modal testing is also carried out to determine the natural frequencies. The measurements and simulations show that low frequency components of the vibrations can be used as identifiable signatures for condition monitoring of induction motors. The patterns presented by the faults allow to discriminate between them.","PeriodicalId":185737,"journal":{"name":"2007 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114857156","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}

Currently the most frequent source of a drive breakdown is a defect of the bearings, which at the same time is most difficult to detect especially under inverter operation. The exploitation of the transient current slope was shown to give an accurate means to identify the machines transient reactances and thus also to detect possible asymmetries in the airgap. In this paper the influence of different types of eccentricity on the transient current slope of the machine excited by voltage pulses is investigated. Special attention is paid to the influence of combined static and dynamic eccentricity as this combination, due to the non linear behavior of the lamination gives rise to specific modulation that is clearly detectable. The investigation is done at machines with two and four pole pairs. The signal obtained corresponds to the inverse transient reactance. It contains different components of inherent asymmetries in the machine as well as in the case of eccentricity additional modulations that can be extracted. For a machine with two poles static eccentricity leads to a change in the signal offset, whereas dynamic eccentricity rotating with the rotor leads to a modulation with twice the mechanical frequency of the rotor. Mixed eccentricity finally leads to change in signal offset as well as a modulation corresponding to a fundamental wave with respect to the mechanical frequency. For a machine with four poles it is advantageous to use the signals obtained from single phase excitation separately.","PeriodicalId":185737,"journal":{"name":"2007 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130679885","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}
