Training involving diagnoses by current analysis

VME training course - Diagnoses by stator current and tachometric signal analysis
The current analysis based diagnosis is a technique which is complementary to the very high-performance vibratory analysis for all shaft line faults generating torque or speed fluctuations. It is also possible to analyse tacho signals for speed fluctuations, provided the signal processing phase is properly adapted.

Motors et generators:

  • Technology and alterations
  • Vibratory and electrical typology of the alterations

Analysis of the electric current and tacho signals:

  • Diagnosis of the faults inducing torque fluctuations, backlashes, regulation faults, coupling faults, torsional resonance.
  • Advanced techniques for processing this type of signals
  • Definition and implementation of the surveillance indicators
  • Implementation of the measurement and analysis techniques on three-phase motor didactic bench.

Staff from mechanical and electrical departments with knowledge of vibratory diagnoses, wishing to supplement it with these additional techniques

  • Pre-requisite: VD or VMD traububg ciyrses
  • Know how to use the analysis of electrical currents and tacho signals as a vibratory monitoring and diagnosis tool which supplements the vibratory analysis
  • Acquire knowledge of vibratory and electrical symptoms for the diagnosis of electric motors


  • Dynae is a forerunner in these techniques
  • « Expert » training with advanced theoretical aspect
  • Highly advanced case studies using these techniques

Course duration: 3 days.
During in-company training, it is possible to arrange exercises on your own facilities.
