As a young automobile driver, we were reminded to “Check the Air in the Spare”, referring to the spare tire. The last thing anyone wants is to have a flat tire only to find out that the spare tire is flat as well. This same philosophy applies to your electric motors. The phrase “If you don’t have time to do it once, you certainly don’t have time to do it twice”, is very applicable. The last thing anyone wants is to replace a failed motor only to find out that the spare motor failed on startup requiring a second replacement.

Kyson Pflum, a homeschool graduate, has received the Claud Thompson Decatur Industrial Electric Scholarship to help cover educational related expenses for the upcoming school year. He will be attending Millikin University, completing a double major in Agribusiness and Accounting.  Due to his completion of 16 dual-credit courses through Southeastern University, Hillsdale College, and Richland Community College, he will finish Millikin in 3 years. 

“I don’t shy away from hard work, and I do plan to continue working as much as I am able while attending college, but the Claud Thompson scholarship will help me pay for a portion of my college expenses,” said Kyson. “I appreciate that tremendously.” 

Kyson lives in Central Illinois with his parents and three siblings – with two more on the way that his parents are currently in the process of adopting from Colombia. 

The Claud Thompson Decatur Industrial Electric Scholarship
This scholarship assists students seeking a career in business through the Tabor School of Business (PACE included) at Millikin University or students pursuing engineering technology degrees at Richland Community College. Additional criteria online includes financial need and students who are self-driven and leadership-oriented with a record of community service. High school seniors and college students may apply for the scholarship on the Community Foundation of Macon County website here.

A healthy motor with good Power Quality does not guarantee a reliable system. Overall reliability can be detrimentally influenced by a defective Power Circuit. Studies found that 47% of reduced efficiency in electric motors results from high resistance connections and other Power Circuit anomalies. Power Circuit anomalies create localized heating and degradation that left alone can result in a catastrophic failure or loss of production. Similar to Power Quality, the product of a Power Circuit anomaly is elevated heat. Not only localized heating as a result of the voltage drop across the high resistance connection, but a stator winding temperature increase as a result of the circulating currents flowing though the motor windings in support of the three-phase imbalance. If the motor is already running fully loaded and at design temperature, running with a Power Circuit anomaly can exceed the design temperature, reducing the life expectancy of the motor insulation system.

Power Circuit analysis can be easily performed with the motor running or de-energized (tripped) through In-Rush/Start-Up, Voltage, Current, and Winding Resistance measurements.
