The Basics of Servo Amplifiers

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.


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.

States with the Most and Longest Power Outages

Title Graphic About the Most and Longest Power Outages by U.S. State

With the constant threat of severe storms, losing power is an inconvenience homeowners and businesses alike can expect. Tropical Storm Risk predicts hurricane activity in the North Atlantic this year could be 50% above the last 50-year norm. Understanding which states have the most power outages can help residents better prepare when their electricity fails.

At MRO Electric, we wanted to determine the U.S. states with the most power outages. To find out, we analyzed data from the U.S. Energy Information Administration to determine the average frequency and duration of power outages in each state. Specifically, we used outage data from their annual reports for the last five years (2018-2022). Keep reading to see how your state stacks up.

The U.S. States with the Most and Least Power Outages

With the most annual power outages, Maine is surely left in the dark. The Pine Tree State tops the list with an average of 4.35 power outages every year, a stark increase above the national average of 1.62 per year.

Given that severe weather can lead to outages, it is no surprise that Louisiana is ranked third on our list. According to the National Hurricane Center and USAFacts, Louisiana is one of the most hurricane and tornado-prone states, and with about 2.78 power outages a year, it is not hard to see what is causing these blackouts.

Mississippi, with the most annual tornadoes on average, and Florida, the most hurricane-prone state, also suffer from outages with 2.25 and 2.18 outages per year on average, respectively. The South, with its frequent severe storms, was the region with the most power outages on average and these states certainly contributed. Comparatively, the South experiences about 1.97 power outages a year, the Northeast encounters about 1.64, the West has about 1.50 on average, and the Midwest comes in last with about 1.31 power outages in a year.

The District of Columbia suffered the least from power outages, with about 0.47 per year on average. Utah and Wisconsin are close second and third with 0.60 and 0.75 annual outages, respectively.

Another factor that should be considered when determining the severity of a power outage is how long the outage lasts. Now, let’s take a look at which states had the longest and shortest power outage durations.

The U.S. States with the Longest & Shortest Power Outages

As mentioned earlier, Louisiana is a hurricane and tornado-prone state. This may be why Louisiana has the longest average annual power outages of any state, with an annual average of more than a full day without power (24 hours and 54 minutes), which is four times the national average of 6 hours. Following Louisiana, Maine, with the most average annual outages, also had some of the longest outages lasting up to nearly 16 hours.

Once again, D.C. fares well in terms of outages and has the shortest average annual power outage duration at only an hour of no power on average, which is just a fraction of what Louisiana suffers. Delaware (1 hour and 42 minutes) and Utah (1 hour and 54 minutes) follow, with an average power outage duration of less than two hours. To see more averages of power outage duration, see the map above.

Average Power Outage Time

Understanding the average duration of power outages across different states provides valuable insights for residents and businesses. On average, power outages in the U.S. last about 6 hours. However, this duration can vary significantly depending on the state and the cause of the outage. For example, states prone to severe weather events like hurricanes and tornadoes often experience longer outages due to the extensive damage that needs to be repaired. In contrast, states with robust infrastructure and fewer severe weather events tend to have shorter outage durations. By examining these patterns, we can better understand the factors that influence outage times and identify areas that may require infrastructure improvements to enhance resilience and minimize disruptions.

Let’s Shed Some More Light on the Matter…

When evaluating frequency and duration patterns of power outages, major event days (MED), are occurrences that are factored in and necessary for understanding the severity of each. Major event days are defined as any day where outage metrics exceed normal averages. While these can sometimes be attributed to hackers, cyber attacks, and other anomalies, they are usually caused by severe weather patterns like hurricanes and blizzards.

To take a closer look at these power outage metrics across the country, hover over each state in the interactive map below. Find out what you can expect for where you call home.

With the uncertainty of power grid reliability by state in inclement weather, access to quality repairs on weather-damaged parts or new parts is essential. MRO Electric ensures that power outages do not hinder progress by providing experienced service in repairs and same-day delivery of industrial automation supplies.


To determine which U.S. states have the most power outages, we analyzed data from the U.S. Energy Information Administration (EIA) to find out the average frequency and duration of power outages in each state. We used outage data from their annual reports for the last five years (2018-2022). We collected the average duration (SAIDI) and frequency (SAIFI) of outages in each state per year. Then, we aggregated the data into 5-year averages for each state.

We included major event days (MEDs) data in the calculations to ensure we included the most accurate average duration and length of outages per year. A common example of a MED is a serious weather event. Hawaii could not be included in this list due to insufficient data for 2022 and 2021.

Raspberry Pi: A Brief Introduction

If you’re in the tech sector for whatever reason, be it profession or hobby, chances are you have encountered the Raspberry Pi at some point.  At the very least you may have heard of it.  For those who don’t know, the Raspberry Pi is commonly designated as a SBC or Single-Board Computer.  Honestly, this characterization is pretty accurate.  The main computer component of the Pi is the size of a credit card, with the enclosure, you’re looking at a device that is about the size of a pack of cigarettes.

So a small pocket-sized  computer is cool, but what does it do?  Well, surprisingly a lot of things!  Hobbyists use the Pi when working with things such as robotics. Instructors find Pi as an easy way to teach programming languages to students. For the longest time Pi has gained prominence amongst private consumers and institutions. 

However, most recently, Pi has proven itself very useful in the industrial sector as well.

The Beginning of Raspberry Pi

Raspberry Pi’s origins traces back to Cambridge University during the early 2000’s.  A group of engineers headed by Eben Upton sought ways to rekindle interests in programming among a younger generation.  Today, sites like CodeMonkey, have enough demand from children as young as five years old wanting to get into programming.  However, in the early 2000’s programming remained a niche interest that required sophisticated knowledge of computational language to do.   It existed as a far cry from the more streamlined process that we see today.

In 2006 Upton and his team set out to design a small computer no bigger than a credit card, that was widely programmable, affordable, and adaptable in running various programs. Their work finally came to fruition in 2012 with the release of the Raspberry Pi Model B.  Features on this tiny triumph included both USB and HDMI ports.  It also sported a SD card slot for storage capabilities.  Best of all it was all packaged at a price point of $35.  This made it an overnight hit with professionals, educators, and hobbyists alike. 

Integrating Raspberry Pi Into Industrial Automation

So how did this unassuming little single-board computer get the attention of the automation industry?  For starters, it’s a very affordable platform that can complete a multitude of tasks. Additionally the small size of Pi also lends to them being energy efficient.  In the industrial sector, Pi boards can be integrated into sensors and used in server units.  They can be used to help manage and control PLCs. Some independent developers have coded apps that allow a Pi board to be used as a PLC.

Arguably, the largest advantage Pi has in the industry is that it exists as a platform that is not tied to any one manufacturer and can be integrated with a wide variety of equipment. You don’t have to worry about whether it’s compatible with Schneider or Yaskawa.
