Special Issue Information

Dear Colleagues,

Electric motors are widely used in numerous industrial applications. They operate continuously and for long-term periods both at nominal and overload conditions. As such, it is evident that the occurrence of faults is quite frequent. A possible motor failure can lead to temporary shutdown or interruption of the production process, which results in a loss of services and/or supplies. Additionally, the Industry 4.0 framework strongly supports smart manufacturing, complying with sustainability of all the involved systems and operations. Thus, it is of great importance to proceed to fast and reliable assessment of the health status of industrial drives. The development of effective mechanisms for electric motor fault detection has therefore attracted widespread attention from both academical and industrial fields. The goal of this issue is to bring researchers together to share their research findings and present attractive perspectives in the fields of fault detection, diagnosis, and prognosis in industrial motors. Prospective authors are invited to submit original and high-quality papers. Topics of interest include but are not limited to the following areas:

  • Advanced diagnostic approaches for mechanical (e.g., bearings, gearbox, shaft bending, static and dynamic eccentricity), electrical (short circuits, winding interruption, asymmetry in supply voltage, voltage fluctuation, insulation failure, etc.), and electromechanical (rotor bars breaking, rotor end-ring detachment, etc.) faults;
  • Diagnosis of multiple simultaneous faults;
  • Early detection of incipient faults and fault isolation;
  • Multisensor data fusion;
  • Line- and inverter-fed electrical machines;
  • Signal analysis and faults diagnosis during motor operation under harsh conditions;
  • Non-invasive techniques;
  • Predictive maintenance and real-time condition monitoring systems;
  • Discrimination between faulty conditions and healthy conditions under the presence of load oscillations or speed variation;
  • Modern signal processing techniques toward information quality improvement;
  • Enhanced pattern recognition algorithms;
  • Advanced fault detection and diagnosis methods based on artificial intelligence (e.g. supervised/unsupervised machine learning).

Bucket elevators generally operate on a 24/7 basis, and for this reason, one of the main requirements is their high reliability. This reliability can be ensured, among other things, by assessing the technical condition of drive assemblies and working assemblies and taking appropriate measures. Carrying out diagnostic measurements enables periodical monitoring of those mechanisms. Vibroacoustic methods are usually employed in operating conditions to measure vibration velocity and acceleration at specific points, and are used as diagnostic signals. This paper presents the results of tests of the intensity of vibrations generated in the drive unit of a large industrial bucket elevator. The analysis of the results in the time domain and frequency domain served as the basis for evaluating the suitability of the drive, and thus the elevator, for long-term operation. Full article
