So who takes the cake, Biff, the Michigan Wolverine or Brutus Buckeye? The Duke Blue Devil or Rameses the Tar Heel? We turned to X, Instagram, and TikTok to analyze followers of mascots at over 70 major universities across the U.S. So, lay the debates to rest because we crunched the numbers. 

Fans of Brigham Young University or the University of Oregon are in luck thanks to Cosmo the Cougar and The Oregon Duck. These mascots are leagues ahead of their social media competition, and we can see why. They both keep up with trends and maintain consistent posting schedules—and people love to watch Cosmo dance. 

Although The Ohio State University’s Brutus Buckeye is in third place, the contest isn’t very close. The Duck’s combined follower count is almost double that of Brutus Buckeye’s, while Cosmo’s count is over triple.

The three highest-followed mascots can attribute much of their success to TikTok. Fourth-ranked Mike the Tiger of Louisiana State University, on the other hand, is best known for his purple and gold-themed Instagram page. Mike is joined by other Instagrammers like Aubie (Auburn University), Reveille (Texas A&M University), Jonathan the Husky (University of Connecticut), and Big Al (University of Alabama). These mascots are in the majority, as Instagram is the biggest platform for most of the mascots we researched.

While most mascots tend to do their best on TikTok and Instagram, others thrive on X. That’s where Bucky Badger, Golden Gopher, and Cocky all boast their biggest platforms. Even so, Brutus Buckeye has the most X followers of any college mascot, followed closely by The Oregon Duck.

Conferences with the Highest Social Media Following

Next, we wanted to see how the conferences stack up to each other, all mascots considered. 

The Big 12 Conference might have the highest social media following, but it only has one mascot in the 20 highest-followed list. That just goes to show the sheer social media power of the most popular college mascot overall, Cosmo the Cougar.

The Big Ten Conference and the SEC have the next highest social media followings. As the oldest NCAA Division I conferences today, it’s no surprise that together they contain 16 of the 20 highest-followed mascots.

Following in fourth place is the ACC, with Sebastian the Ibis leading the conference in social media followers. Hailing from the University of Miami, Sebastian holds the ACC’s only spot on the top 20 list. Similarly, UConn’s Jonathan the Husky is the only mascot from an NCAA football-independent school to appear on the list.

Representing Washington State University, Butch T. Cougar has the most followers in the Pac-12 Conference. He may not have enough followers to make it on the top 20 list, but he has enough to beat Oregon State University’s Benny Beaver, the only other mascot in the conference.

Closing Thoughts

So there you have it! Whether your mascot made our list or not, we can all agree that game days wouldn’t be the same without them. 

College mascots are an essential part of any team, bringing fans together both on the field and online. At MRO Electric, we understand the importance of a solid team.

Warning Signs of a Failing Servo Motor

Ken Cheng Leave a comment

Whether we want to admit it or not, our entire world economy hinges on the functioning of servo motors. They remain integral components in many industrial applications, from robotics to CNC machinery. Their reliability and precision make them essential for ensuring smooth operation in automated systems. However, like anything else,servo motors can develop issues over time. This tends to lead to catastrophic failure if not addressed. Identifying early warning signs of a failing servo motor can prevent costly downtime and ensure the longevity of your equipment. Below are some of the key signs that a servo motor is about to go bad.

Signs of a Failing Servo Motor

Unusual Noises

One of the most common early indicators of a problem is abnormal noise coming from the servo motor. Servo motors typically operate quietly, but as they wear out, components may loosen or degrade, causing:

  • Grinding or clicking sounds
  • High-pitched squealing
  • Loud vibrations

These noises can be caused by worn bearings, misaligned gears, or internal mechanical friction. If you hear unusual sounds, it’s critical to investigate and address the underlying issue before it escalates.

Overheating

Servo motors are designed to dissipate heat effectively, but if a motor is consistently running hotter than normal, it could be an early sign of trouble. Overheating can stem from:

  • Poor ventilation or cooling
  • Overloading or running the motor beyond its rated capacity
  • Worn-out bearings or brushes causing friction

If you notice the motor surface temperature exceeding the manufacturer’s recommended levels, or if the motor’s thermal protection trips frequently, it’s time to assess the system for possible issues.

Erratic Movement

Servo motors are known for their precision. If you notice that the motor is no longer operating smoothly, it could indicate impending failure. Symptoms include:

  • Jerky or erratic movements
  • Delays in response time
  • Inconsistent speed or torque output
  • Inaccurate positioning or tracking

These issues could be due to encoder or feedback problems, damaged internal gears, or failing control circuitry. A motor that cannot maintain steady operation should be inspected immediately.

Increased Power Movement

A servo motor nearing failure may begin to draw more power than usual to maintain its performance. An increase in energy consumption could result from:

  • Excessive friction in the bearings or mechanical parts
  • Electrical short circuits or insulation breakdown
  • Worn-out windings requiring higher currents to produce the same output

Monitoring the power consumption of your motor can give you early insight into its health. A sudden spike in current usage often signals internal degradation.

Vibrations and Excessive Play

Vibrations are a telltale sign of wear in mechanical systems. A failing servo motor might exhibit:

  • Excessive vibrations or wobbling during operation
  • Loose or imprecise shaft movement
  • Increased backlash in the gearbox

These issues are typically caused by worn-out bearings, misaligned shafts, or damaged couplings. In some cases, vibrations can also result from imbalances in the rotor. Ignoring these warning signs can lead to more serious mechanical failures down the line.

Encoder Malfunctions

The encoder plays a critical role in providing feedback on the position, speed, and direction of the motor. If the encoder starts to malfunction, you may notice:

  • Loss of feedback signals
  • Incorrect positioning of the motor
  • Communication errors between the motor and controller

Dirty or misaligned encoders, damaged cables, or electronic component failure can all lead to encoder-related issues. Regularly inspecting and cleaning the encoder can help mitigate these risks.

Frequent Power Tripping

Servo motors are typically equipped with protective features such as thermal cutoffs, overload protection, or circuit breakers. If these devices trip more frequently than usual, it’s an indication that something is wrong with the motor. Common causes include:

  • Overheating or excessive current draw
  • Mechanical obstructions causing overloads
  • Short circuits or electrical insulation failure

Frequent tripping should never be ignored, as it indicates the motor is under stress and could fail soon.

Wear and Tear

Physical inspection of the motor can also reveal signs of impending failure. Look for:

  • Damaged or worn-out seals or housings
  • Oil or grease leaks around the bearings or seals
  • Corroded or frayed wires
  • Signs of rust or corrosion on metal components

While external wear might not always correlate directly to internal damage, it’s a good practice to maintain the motor’s appearance and prevent environmental factors from accelerating its deterioration.

Internals of a well worn servo motor are a telling indicators of a failing servo motor.

Software and Control System Errors

Servo motors often interact with control systems via software or programmable logic controllers (PLCs). If you start noticing frequent errors, alarms, or faults in the control system related to the servo motor, it could be a sign of:

  • Communication issues between the motor and the controller
  • Malfunctioning or outdated control software
  • Feedback loop problems due to encoder failure

Diagnosing these errors quickly can help you address the root cause before it leads to further damage to the motor or system.

Motor Stalling

If the servo motor stalls or fails to start under load, it could be an indication that the motor is struggling to produce the required torque. Potential causes include:

  • Mechanical binding or obstructions in the system
  • Electrical issues such as worn windings or damaged brushes
  • Degraded motor insulation or faulty wiring

A stalling motor is a serious issue that should be addressed immediately to avoid a complete motor burnout.

Conclusion

A failing servo motor can be costly, both in terms of downtime and replacement costs. By recognizing the early warning signs such as unusual noises, erratic movement, overheating, and increased power consumption, you can address minor issues before they escalate. Regular maintenance, monitoring, and timely inspections will help ensure the long-term performance and reliability of your servo motors. When in doubt, consult a professional technician to evaluate and service your motor, ensuring it continues to operate smoothly and efficiently.

Ken Cheng Leave a comment

The fast-paced world of industrial automation remains constantly in motion.  In an environment that moves fast, the ability to diagnose and quickly control a fault remains crucial to operating an industrial machine efficiently and safely. Having a servo amplifier safety features saves money, time, and lives in the long run.  

Read more: Servo Amplifier Safety Features

Before we get into the multiple safety features of servo amplifiers. If you are not familiar with servo amplifiers, this article covers the fundamentals of what servo amplifiers are. Definitely give it a read over!

Overcurrent Protection

Overcurrent protection exist as the most fundamental safety feature found on servo amplifiers.   This mechanism prevents excessive current from flowing through the amplifier. Excessive current flows occur due to short circuits or sudden surges in demand. When an amplifier detects overcurrent,it shuts down or reduces power. This avoids overheating and potential damage to the motor and the amplifier itself. This not only preserves the lifespan of the components but also mitigates fire hazards associated with electrical overloads.

Thermal Protection

Another safety feature found in servo amplifiers, thermal protection use integrated sensors to monitor servo amplifier temperatures. These sensors initiate protective measures if temperatures rise above safety thresholds.  This usually involvesreducing the power output, activating cooling fans, or even shutting down the amplifier to prevent thermal runaway and damage. Effective thermal management ensures continuous, reliable operation and extends the equipment’s service life.

Over/Under Voltage Protection

Overvoltage conditions can arise from fluctuations in the power supply or regenerative energy from the motor, potentially damaging sensitive electronic components. Undervoltage situations can impair the amplifier’s performance, leading to erratic motor behavior. By monitoring and maintaining voltage within safe limits, these protective mechanisms ensure stable and predictable operation, safeguarding both the amplifier and the connected motor.

Fault Detection and Diagonistic

Advanced servo amplifiers often incorporate fault detection and diagnostic capabilities.  These systems continuously monitor operational parameters and can identify anomalies such as motor stalls, feedback errors, or communication failures. When a fault is detected, the amplifier can trigger alarms, log diagnostic information, and take corrective actions such as switching to a safe state or performing an emergency stop. This proactive approach to fault management not only prevents potential damage but also aids in troubleshooting and maintenance, reducing downtime and operational costs.

The Basics of Servo Amplifiers

Ken Cheng Leave a comment

When thinking about automation, we imaigne massive warehouses housing automation lines that have conveyer belts snaking every which way.  Large robotic arms constantly move back and forth as they commit to the same repeated task over and over again.  You probably imagine sparks flying in the air as robotic arms weld parts to march larger machine bodies. The sight of a manufacturing facility may overstimulate the senses. The flashes of light, the sound humming and grinding, and the smell of various mechanical fluids in the air.  With so much stimulation, it’s understandable as to why people overlook the comparatively small but very crucial amplifier.  After all these small devices sit tucked away hidden from sight. Nonnetheless they perform the very important function of orchestrating tasks to other units with extreme precision.

The History of Servo Amplifiers

The history of servo amplifiers dates back to the 1920s where their original exploration largely targeted aviation and military applications.  During the bulk years of WWII during the 1940s, early servo mechanisms saw their use controlling gun turretts and radar.  Notice how I said “”servo mechanisms,” that’s because these weren’t quite the servo amplifiers that we are familiar with today. Instead they required hydraulic and manual action.  The end of the 40s and into the 1950s saw the development of the first electronic servo amplifier. The servo amplifier stood as a vast improvement compared to its predecessor, in regards to precision and reliability. 

The 1960s and 70s brought the invention of the semiconductor and with that the next evolutionary step for servo amplifiers.  In 1969 the company, Modcon, built the first Programmable Logic Controller (PLC). Not only did the PLC revolutionize the automation industry but it also paved the way for more sophisticated control systems. By the 1980s, the integrating of digital signal processing (DSP) furthered the capabilities of servo amplifiers. By the 1990s, servo amplifier connectivity and communication made it an irreplaceable asset to industries across the globe.

How Do Servo Amplifiers Work

At the core of its functionality, the servo amplifier is a feedback device.This system relies on sensors, typically encoders or resolvers, to provide real-time data on the motor’s performance. The feedback loop continuously compares the actual position, speed, and torque of the motor with the commanded values from the control system.The servo amplfifier corrects any discrepencies by adjusting the power output accordingly. This closed-loop system ensures high precision and responsiveness, enabling complex and delicate tasks to be performed with ease.

Servo amplifiers come in various types, each suited to specific applications. Analog servo amplifiers, for example, control motor operations using continuous signals. Digital servo amplifiers, on the other hand, offer greater flexibility and precision by utilizing digital signals and advanced algorithms. These digital models often feature programmable settings, allowing for customization to meet the specific requirements of different tasks. Additionally, hybrid servo amplifiers combine elements of both analog and digital systems, providing a balance of performance and versatility.

The applications of servo amplifiers are vast and varied. In industrial automation, servo amplifiers control robotic arms, conveyor belts, and CNC machines, where precision and repeatability are essential. In the aerospace industry, servo amplifiers are critical for controlling the movements of aircraft components, such as flaps and landing gear. Servo amplifiers also find use in the medical field, where they enable the precise operation of surgical robots and diagnostic equipment. The ability to provide exact control over motor functions makes servo amplifiers indispensable in any field requiring high-precision motion control.

Conclusion

In summary, servo amplifiers are crucial devices in the realm of motion control, offering unparalleled precision and reliability. By continuously adjusting power based on feedback from sensors, they ensure motors operate efficiently and accurately. The variety of servo amplifier types allows for their use in a wide range of applications. This ranges from industrial automation to aerospace and medical technology. As technology advances, the role of servo amplifiers is expected to grow. Further enhancing their importance in achieving precise and efficient motor control.
