Il concorso di idee
2007
Il Polo Universitario di Agrigento, seppure recente e funzionale, sta ormai diventando insufficiente ad ospitare tutte le attività didattiche che vi si svolgono, le attività di ricerca ed i servizi per gli studenti. Queste riflessioni, insieme ad una protesta degli studenti universitari, che quotidianamente vivono tali disagi, hanno portato al ripensamento di alcune previsioni urbanistiche e al deciso ed immediato potenziamento infrastrutturale, in funzione della popolazione coinvolta, presente e futura. Il concorso ha visto la partecipazione di numerosi studenti universitari provenienti da tutta Italia ai quali si chiedeva, da bando, un insieme coordinato di interventi di progettazione urb…
Double squirrel cage induction motors: A new approach to detect rotor bar failures
2013
The purpose of this paper is to present a diagnosis technique, for rotor broken bar in double cage induction motor, based on a combined use of frequency sliding and wavelet transform analysis, to isolate the contribution of the rotor fault components issued from vibration signals in a single frequency band. The validity of the proposed diagnosis approach is not limited to the analysis under steady-state operating conditions, but also for time-varying conditions where rotor fault components are spread in a wide frequency range.
Monitoring and Diagnosis of Failures in Squirrel-Cage Induction Motors Due to Cracked or Broken Bars
2011
In this paper three diagnostic procedures, based on on the vibration, current and instantaneous power monitoring for the detection and monitoring of incipient faults as cracks or bar breaks on squirrel cage motors are briefly reminded. The experimental investigations, carried out at the SDESLab (Sustainable Development Energy Savings Laboratory) of the University of Palermo in order to underline merits and drawbacks of the methods applied to the same die cast squirrel cage induction motor, are presented. The results of the investigations confirmed the effectiveness of the diagnostic procedures here considered.
