Electrical machine diagnosis services

Industrial experiences demonstrate that major faults typically result from a series of minor faults that go unnoticed during routine inspections. Advanced diagnostic techniques can effectively monitor the progression of minor faults, enabling a proactive maintenance strategy.

Rotor bar diagnosis

We provide a comprehensive analysis of the health of rotor bars using advanced transient current analysis techniques, offering to:

 

  • Assess the condition of rotor bars and end rings relative to their original brand-new state.
  • Monitor the progressive deterioration of rotor bars containing microcracks, which could potentially lead to major faults in the future.

 

Both processes can be conducted online or off-line, tailored to your specific industrial requirements.

Misalignment and load unbalance

We provide a thorough assessment of the quality of motor-load alignment and load unbalance issues using non-invasive techniques, offering:

  • Evaluating the condition of bearings and alignment between motor and load using advanced non-invasive analytical techniques.
  • Monitoring the progressive deterioration of bearings causing static and dynamic eccentricity, which could potentially lead to major faults in the future.

Both services can be carried out online or off-line, tailored to your specific industrial requirements.

Partial Demagnetization Diagnosis

We provide services to dectect partial demagnetization of magnets within PMSMs, identifying the root causes. We offer:

  • Evaluating the condition of permanent magnet health, considering partial and trail-edge demagnetization using advanced non-invasive techniques.
  • Prognose the state of health of magnets according to past measurements, helping to extend the lifespan of the drive if possible.
