These techniques may provide, in certain situations (unbalance supply voltages, load torque oscillations…), substantial advantages in comparison with the classical method, based on the Fourier spectrum of the steady-state current. Nevertheless, these transient-based techniques have been mainly focused on the tracing of the left sideband harmonics (LSH) introduced by the asymmetry. In this paper, Wigner-Ville distributions are applied to the detection of other high-order components introduced by the asymmetry. Their detection might help to reach a more reliable diagnosis conclusion in cases in which the tracing of the LSH may be difficult (inter-bar currents, load torque oscillations…). The results show the potential of the tool for the detection of these components as a basis to diagnose the fault.","PeriodicalId":405777,"journal":{"name":"2009 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121825419","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}

They usually involve supplying a single phase or two series-connected phases. An ideal machine should present the same behavior at all terminals, while in an actual machine non-idealities alter the response to the signals. Some techniques to state machine condition during self-commission procedures based on the parameter values discrepancies or on the response to particular signals injected have been proposed. This paper investigates the effect of the different asymmetries on the usual self-commissioning procedures and the further possibilities given by the machine supply through the digitally controlled inverter. It is shown that, even at standstill, it is possible to detect and state the severity of some fault conditions of the machine. In particular a specific supply voltage signal is proposed that, through the machine response, outlines the machine rotor conditions.","PeriodicalId":405777,"journal":{"name":"2009 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126632477","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}

Voltage unbalance produces power oscillations at twice the supply frequency, which introduces, in turn, torque oscillations and vibrations at this frequency.

The effects of voltage unbalance on the oscillation of motor power, torque and vibrations are extensively analyzed through experimental results. These experiments are performed for induction motors with different rotor characteristics, showing that the motor behavior under voltage unbalance significantly changes according to the rotor construction.","PeriodicalId":405777,"journal":{"name":"2009 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131818153","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}

Kapton films and coated wires were subjected to an accelerated aging under combined stresses (VRMS, frequency, DC voltage, and temperature).

Frequency shift from 1 to 10 kHz is more hazardous than a voltage shift from 0.7 to 1.2 kV or a temperature shift from 150 to 200°C. Adding a DC voltage as 200V increased the sample life time.

Rotor fault distorts the magnetic symmetry and subsequently deteriorates the steady-state and dynamic performance. As fast speed control loop compensates for the unevenly distribution of the field, the inverter supply voltage is adjusted accordingly. The modulated supply voltage pattern is then analyzed and its average duty cycle is determined. When broken rotor bars are present, specific oscillations in the average duty cycle arise. The presence of these oscillations is sufficient for a successful detection. The computation is performed using simple mathematics and demands no significant computational power. The results confirm the suitability of the proposed detection method for FOC scheme.","PeriodicalId":405777,"journal":{"name":"2009 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123135696","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}
