What if the key to making electric motors more reliable isn’t a complex new technology but a better understanding of the fundamentals of electrical engineering?

In this episode, we sit down with Mark Gurney, a reliability and electrical engineering expert, to hear his journey from troubleshooting issues at biogas plants to leading a full-scale reliability program at an Australian dairy company. Mark takes us behind the scenes of a commonly overlooked problem, electrical fluting in bearings. He breaks down why strong motor management and condition monitoring practices are essential for long-term reliability.

We also dive into the broader impact of electric motors in industrial settings and the small yet powerful maintenance habits that make a difference, like using silica gel packs to keep humidity in check. Mark shares his insights on the importance of cleanliness, professionalism, and passing on knowledge to the next generation of engineers.

You'll hear real-world lessons from his time on biogas sites, including how proper earthing and a structured troubleshooting approach can prevent serious issues like bearing currents. He also highlights the value of hands-on training programs that bridge the gap between theory and practice.

As we wrap up, we touch on upcoming discussions around shaft current problems and thank Mark for sharing his knowledge. We can’t wait to have him back for more.
