Todd and Noah Show
In this series "Taking the Mystery Out of Electric Motors", Noah Bethel and Todd Gunderson will demystify motors to help industry professionals better understand them.
Episodes
Taking a look at the next step in electric motors. In this episode, Todd and Noah talk about today's technology, how it looks forward to tomorrow in continuous monitoring and the benefits of doing so.
What is current demodulation? Todd and Noah take a deep dive into its use and the mechanical anomolies found in the current system.
In Part 2, Todd and Noah take the mystery out of electric motors. They give you the tell-all about synchronous and DC motors and their functions.
Per listener request, Todd and Noah discuss the induction motor, its construction and what they're used for.
Although not an actual fault zone, the machine train is considered an important peripheral that is attached to and affects the motor. Fans and pumps are both mechanical components that can be analyzed when talking about the machine train. Listen to this episode to hear Todd and Noah go into detail about the machine train.
You can have a perfect rotor, and you can have a perfect stator. But if those two are not balanced and symmetrical, problems can occur. Today, we discuss the Air Gap in a motor. Air gap issues occur during the offset of the rotor and stator, which is why it is so important to regularly inspect and rotate motors.
In this episode, we discuss the tangible, moving part of the motor; the rotor. It is the rotating part of the asset which is very important in the success of the motor. A study done a while back blamed 10 percent of motor failures on the rotor. We will go over what can go wrong in the rotor today.
Today, we go through some case studies involving a very important fault zone: the Stator fault zone which is the stationary part of the motor. It is very critical because once this fails, you're pretty low on the PF curve. We also discuss how to differentiate between the Insulation fault zone and the Stator fault zone.

In this episode, we talk about the Charlie Brown fault zone: Insulation. Back in the 1840's, one of the first forms of insulation which was developed to prevent electricity from getting to a person or ground, was glass. Eventually in the late 1800's, insulation became things like porcelain, PVC, and rubber. Today, they use products like epoxy resin and synthetic polymers. Tune in to hear more about the evolution of insulation and w...
Today, we discuss ways in which the power circuit can help save on efficiency. Because energy costs are so high, we want to be efficient. A multi-year study done by EPRI (Electric Power Research Institute) showed that connectors and conductors are the source of almost half of the faults, reducing motor efficiency.

Today, we talk about IEEEs (Institute of Electrical and Electronic Engineers), our favorite standard of reference when talking about establishing alarms and limits. They are well respected around the world and they implement many alarm subpoints into motors after looking at many bodies of knowledge. We also discuss what data we should be collecting to determine whether there are power quality issues.

Welcome to episode one of the Todd and Noah Show!
We will be taking the mystery out of electric motors throughout this podcast to help industry professionals. Many people say smoke runs the motor, and the goal with electric motors is to keep the smoke in because it is very expensive to replace once it is out. Throughout this 12 part series, we will be diving deep and demystifying motors to make it more digestible so industry profe...
