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…
