Understanding FANUC Servo Motor Issues

When it comes to FANUC servo motor repair, understanding the common issues that can arise is the first step towards ensuring their reliable performance. These motors are crucial for the precise movements and operations in various industrial applications. Here, we break down the typical problems and the methods we use to diagnose and fix them.

Feedback Repair and Realignment

The feedback mechanism in a servo motor is critical for accurate positioning. If the feedback device, such as an encoder or resolver, is misaligned or malfunctioning, it can lead to positioning errors. Realignment and repair of these devices are precise tasks that require expert handling to ensure the motor functions as intended.

Testing Methods

Ohm Testing is a straightforward yet essential diagnostic tool. By measuring the resistance (ohms) between the motor’s phases, we can identify issues such as short circuits or open circuits. A normal range should be between 0.3 and 2.0 ohms. Anything outside this range indicates a problem that needs further investigation.

Carbon Dust Buildup

Over time, the carbon brushes in DC servo motors wear down, leading to carbon dust accumulation inside the motor. This buildup can cause short circuits and other failures. Part of our repair process involves thoroughly cleaning the motor to remove this contamination and prevent future issues.

Armature Failure

In both AC and DC FANUC servo motors, the armature can fail due to excessive carbon dust buildup or other factors. Unlike many repair services that might consider such motors beyond help, we have the capability to rewind armatures and replace commutators. This approach not only saves the motor but also extends its life significantly.

By addressing these common issues with precision and care, we ensure that each FANUC servo motor we repair meets the highest standards of performance and reliability. Our detailed understanding of these motors’ intricacies allows us to offer comprehensive repair solutions that keep your operations running smoothly.

Each motor that comes to us goes through a rigorous series of tests to ensure it meets our high standards for performance and reliability. Here’s how we do it:

Electrical Testing

We start with electrical testing to catch any issues that might not be visible on the surface. This includes checking for shorts, opens, and ground faults. We measure resistance and insulation to ensure everything is within the manufacturer’s specified range.

Mechanical Testing

Mechanical integrity is crucial for the longevity of a servo motor. We check for any mechanical wear or damage, including bearing conditions, shaft alignment, and any signs of physical impact that could affect performance.

Load Testing

We don’t just want the motor to work; we want it to work under the conditions it will face in its everyday environment. Load testing helps us see how the motor performs under various loads, ensuring it can handle the demands of its application.

Back EMF Testing

Back Electromotive Force (EMF) testing is vital for understanding the motor’s efficiency and ensuring that the magnetic fields are functioning correctly. It’s a clear indicator of the motor’s health and performance capabilities.

Magnetic Strength

We assess the magnetic strength of the motor to ensure it hasn’t degraded over time. A loss in magnetic strength can lead to a decrease in performance and efficiency.

Independent Torque Testing

Torque is the motor’s ability to perform work. By conducting independent torque testing, we can verify that the motor delivers the power needed for its specific applications.

Ensuring Precision and Reliability

Ensuring that a repaired FANUC servo motor can be trusted in critical applications means paying attention to every detail. Here’s how we guarantee precision and reliability in every repair:

  • Shaft Tolerance Verification: Even minor deviations can lead to significant issues. We verify shaft tolerance to ensure smooth operation and prevent undue wear on other components.

  • Stator Winding Checks: Stator windings are essential for motor operation. We check for any signs of damage, degradation, or improper winding that could affect performance.
