Stator Inter-Turn Stress with Electrical Signature Analysis in Variable Frequency Drive Applications
Incorrect settings in a Variable Frequency Drive (VFD) application have an impact on the windings of an electric motor. When a drive is not set correctly, or not tuned when not using straight volts/hertz settings, stresses occur between the turns in a winding. In some cases, this will appear as small Partial Discharges (PD), and in others it can be increased leakage between turns. When these conditions occur, they introduce small current discharges that effect the air gap magnetic field of the motor.

Stuart Walker looks at how utilizing the latest visual vibration technology can assist in getting to the root cause of many industrial vibration problems.
Stuart goes through a number of case studies on rotating plant, pipework and structures whereby visualizing the vibration was a key part in understanding the problems right through to rectification and follow up.

This presentation will begin with a brief history of Mobius Institute with a focus on why we exist. Then Jason Tranter, the founder of Mobius, will discuss how vibration analysis, and the other condition monitoring technologies all deliver tremendous value. Every organization's goal must be to eliminate the reasons why failure occurs, not just detect the failures themselves. Improving reliability has proven to be terribly difficult, and that is why the Asset Reliability Transformation [ART] exists. Jason will discuss his frustration with the way most people have had to approach their reliability improvement initiative and how ART resolves all those issues.

The 2020 calendar year has certainly brought with it many challenges for a variety of industries. The medical field, pulp and paper industry and food supply chain have all been significantly impacted by the unprecedented COVID-19 pandemic. At the grocery store, people experienced (or are still experiencing) empty shelves, limited food supply and less variety when doing weekly shopping. In March 2020, grocery and supply sales increased 29% from the previous year (3).

More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..
