An innovator in autonomous mobile robots (AMRs) successfully launched a new platform by partnering with ADVANCED Motion Controls to resolve complex network integration challenges. Through systematic diagnostics led by AMC applications engineers and targeted hardware modifications, the customer scaled production and accelerated their time-to-market. The Challenge: High-Density Power for an Ambitious AMR Design A developer of advanced AMRs was designing…

In the current global supply chain landscape, the physical location of your servo drive manufacturer is a critical risk factor. At ADVANCED Motion Controls, we adhere to a "Designed and Built in the USA" philosophy. This ensures that while we source top-tier components globally, the critical loop between Design, Manufacturing, and Testing happens under one roof in Camarillo, California, maximizing…

In motion control, “servo drive” and “servo controller” get used interchangeably all the time. That’s understandable — but it’s wrong, and the confusion costs engineers hours of troubleshooting they shouldn’t need to do. Here’s the clearest way to put it. The servo controller is the brain: it plans the motion, generates commands, and coordinates axes. The servo drive is the…

We hear the term “closed-loop control” all the time—especially in automation, motion control, and servo systems. But what does it actually mean? And more importantly… why do engineers care so much about whether a system is open-loop or closed-loop? At its core, closed-loop control is a simple idea: measure what happened, compare it to what you wanted, and automatically correct…

IP65 is an ingress protection rating defined by IEC standard 60529, meaning the enclosure is completely dust-tight and resistant to low-pressure water jets projected from any direction. Two digits. One decision. (Though “corrodes from the inside out” tends to focus the mind.) IP stands for Ingress Protection — the IEC 60529 classification system covering steel, stainless steel, polycarbonate, and aluminium…

So what actually separates these two motor types at a fundamental level? A brushed motor differs from a brushless motor in how it commutates: mechanically via carbon brushes and a copper commutator versus electronically via an external controller and Hall-effect sensors. That single architectural difference determines efficiency, lifespan, maintenance burden, and cost. The first brushless DC motor was developed in…

DC servo motors are a key element in motion control systems that demand precision, speed, and repeatability. They combine a DC motor with a feedback device, such as an encoder or potentiometer, and a controller to regulate position, speed, or torque in a closed-loop system.  The controller continuously compares feedback to the target input and adjusts power to minimise error,…

Servo motors are built for precision, whether it’s holding a position, helping to trace a toolpath, or maintaining a set speed under load.  But even the most reliable systems have their limits. Push those too far, skip routine checks, or operate in less-than-ideal conditions, and you'll start seeing servo motor faults creep in, sometimes gradually, sometimes with a (literal) bang.…

An AC servo motor is the powerhouse in many applications, as it’s known for generating precise motion control. You can find AC servo motors in different technology pieces ranging from home appliances to more advanced pieces like aircrafts and robots.  In this article, we’ll focus in detail on the mechanism of an AC servo motor, its parts and functions, and…

Not all servo motor types are the same, as they come in a wide range of shapes and sizes, with each type being suited to different applications. Well, perhaps the range of shapes is not so wide, as they all tend to be approximately cylindrical or rectangular in shape, depending on if they are rotary or linear.  But servo motors…

Servo Drives and Servo Amplifiers make up a tiny fraction of all of the types of amplifiers in the world. We thought it would be fun to explore all types of amplifiers and then see how servo amplifiers fit in. Amplifiers are found in all manner of devices in modern life. If you’re reading this article on a cellphone, you’re…

For the past several years, the story of servo drive development has been a relentless pursuit of power density. The primary challenge was clear: pack more power into a smaller package. While that mission continues, the industry is entering a new phase of maturation. In 2025, the most significant trends aren't just about raw performance, but about the intelligence, safety,…

The concept of bandwidth isn’t just something that communications engineers need to worry about. Bandwidth is also a fundamental concept in industrial servo systems. The speed at which a servo system responds to commands is determined by the servo bandwidth.  For motion control systems requiring high accuracy and responsiveness, this is vital information to know. In this article, we’ll discuss…

Choosing the right servo motor for your industrial application is vital for achieving the right balance of functionality, reliability, and of course, cost. Selecting the wrong motor can result in degraded performance (if it even performs at all), damage to ancillary hardware, system failure, and further downstream, quality issues in the goods or services that you are providing. In this…

Today, servo motors and drives power everything from robotic arms to large-scale manufacturing equipment. We will discuss the longevity of these components, providing insights into how you can significantly extend their operational lifespan. How Long Does a Servo Motor Last? A servo motor, essential for precision in applications ranging from robotics to manufacturing, exhibits lifespans that vary significantly depending on…
