Servo Motor Repair

What Does a Servo Motor Do, and How Does It Work?

Servo motors are a special type of electric motor designed to effectively balance power, control, and energy efficiency for a variety of applications. The servo system is a closed-loop mechanism of fairly simple design, but with lots of payoffs in terms of performance. The servo system typically includes a PLC controller, a drive or amplifier, a motor, and a feedback system. Modern servo motors are sometimes referred to as servo drives, since the drive and other necessary components are often built right into the integrated servo motor housing.

Servo motors come in both AC and DC designs. The AC servo motor can handle higher currents and surges, and is often preferred for many larger machinery applications. DC servo motors are better suited for smaller applications, but in some cases, DC servos can be better solutions for some industrial applications as well. For example, DC servo motors work well in circumstances where continuous rotation is needed. For many commercial, medical, and industrial uses, it’s also very important for a servo motor to be able to demonstrate critical positioning and speed sensing abilities, too. Servo motors are utilized for everything from robotics to manufacturing to pharmaceuticals to food services, and much more.

What Can Lead to Servo Motor Failure?

Servo motors are very efficient and dependable, but they still require regular preventative maintenance for optimal performance and longevity. We repair & service a lot of servo motors at AES, and we’ve seen a little bit of everything. Here are some of the most common issues that can crop up:

Overheating

Overheating is a potential threat to any electrical or mechanical device, and since servo motors are really a combination of both, they are prone to heat damage. A single overheating event may not kill your motor instantly, but each instance usually serves to reduce the lifespan of the servo.

Overcurrent & surge issues

Power spikes, surges, and faults from connected machines can all spell doom for a servo drive system, especially in the case of any internal circuit board components present. It’s important to ensure your power supply is regulated, and to make sure you’re maintaining sufficient surge protection for your equipment.

Moisture infiltration

The introduction of any excessive moisture or humidity can cause servo motor components to function at sub-optimal levels. Worse still, moisture can lead to component degradation, deterioration, and rust. These negative impacts from moisture are even further amplified in closed-body motor designs. It’s imperative to regulate your servo environment for moisture and humidity control.

Dirt, dust, & other contaminants

Moisture isn’t the only threat when it comes to infiltration. Dust, dirt, and debris can also produce many of the same negative impacts experienced with moisture infiltration. The buildup of debris can block or jam internal parts, including cooling fans. And whenever that happens, the threat of overheating also becomes more likely.

Vibrations & balance issues

Servo motors often spin at some high RPMs, so it’s very important for everything to be maintained in a precise balance for power, efficiency, and longevity. Vibrations can develop as a result of a loose or damaged part, a misalignment, introduction of foreign materials, or as a result of accidental drop or impact. It’s a good idea to inspect your servo motor fittings and alignments on a regular basis.
