Webinar: 'Is your AC-motor VFD ready?' by AEGIS - 18 October 2022, 10 AM CEST

Join us at the free webinar “Is your AC-motor VFD ready?” proposed by AEGIS, scheduled on Tuesday 18 October 2022 at 10 AM CEST, dedicated to EASA Members and Friends.

All major manufacturers of 3-phase AC motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, their most vulnerable parts — the bearings — are too often ignored. Without some form of mitigation, shaft current can discharge through bearings, causing motor failure and downtime. To be considered truly “inverter-ready”, a motor must have proven long-term bearing protection in addition to inverter-rated insulation. Unfortunately, many purchasers of these motors do not understand this. And, mission-critical facilities, in which downtime can have disastrous consequences, are especially vulnerable to motor failures.


  • Root causes of shaft voltage
  • Impact on the bearings
  • Possibilities to proof
  • Mitigation strategies
  • Application examples
