Free Live Q&A Session! 

Have questions related to Motors and Generators? Bring them to our live Q&A session and our Iris Power experts will be there to answer

Join our experts to answer your questions on topics related to motors and generators. If you have implemented a condition monitoring solution or are planning to monitor your machines in the future, this Q&A webinar is for you! 



Plant personnel, rotating machine engineers, reliability engineers or if you are involved with rotating machine. Join us to get answers of any problems you are facing, an interesting idea you want to share, a doubt you have or to share your knowledge on assets.



For the first time ever, we've combined all of our rotating machine experts in ONE place virtually to be able to provide you with comprehensive information regarding motors and generators. Get your questions ready - in the meantime, here are some sample questions from our previous webinars to give you some inspiration for our upcoming event:

  • [ Suggested Topics and Questions ]
  • What do increasing trends suggest
  • Q: What failures could be suggested by increasing Flux trend?
  • Q: For a new machine, when to start PD monitoring ?
  • Q: What would suggest an alarm on endwinding movement?
  • Understanding data analysis and correlating data
  • Q: New standards on vibration monitoring for hydrogenerators
  • Q: Looking at real time movement of the endwindings, what information does it provide?
  • Q: Why do we focus on 50/60Hz on end winding vibration
  • Q: Is it worth correlating Airgap, flux, bearing vibration, PD, operational data simultaneously?
  • Truths and myths of condition monitoring
  • Q: Can we tell time to failure of a machine?
  • Q: Can online monitoring replace visual inspection?
