Introduction

Fanuc motors are widely employed in industrial settings, known for their reliability and precision. However, like any machinery, they may require repairs due to wear, electrical faults, or mechanical failures. This article provides a detailed guide on repairing Fanuc motors.

Identifying Issues with Fanuc Motors

Common issues include abnormal noises, overheating, and failure to start. These symptoms can often be traced to problems in the bearings, windings, or electrical connections. Accurate identification of the issue is critical for effective repair.

Repairing Fanuc Motors

Initial Diagnostics

Conduct visual inspections and use diagnostic tools like multimeters and oscilloscopes to check continuity and measure voltage levels. Essential parameters to check include:

• Resistance: Ensure the resistance between windings is within the specified range, usually between 0.5 ohms to 5 ohms.
• Insulation Resistance: Perform insulation resistance tests using a megger; values should exceed 1 MΩ.

Disassembly Procedures

Before disassembly, ensure the motor is powered off and disconnected. Follow these steps:

1. Remove the motor from the equipment.
2. Disassemble the motor casing, taking care to document each step for accurate reassembly.
3. Extract the rotor and stator safely, ensuring no damage to the winding.

Component Repair and Replacement

Inspect and address the following components:

• Bearings: Replace bearings showing wear or noise, typically every 10,000 operational hours.
• Stator Windings: Check for short circuits and replace if continuity tests fail.
• Connections: Re-solder any loose or corroded connections.

Reassembly

Carefully follow documented disassembly steps in reverse order. Ensure all parts are secure and correctly aligned to avoid operational issues.

Testing and Calibration

After reassembly, perform testing and calibration to ensure proper function:

• Run the motor without load to check for abnormal vibrations or noise.
• Conduct a full load test and measure temperatures to ensure they remain below 80°C.
• Calibrate the motor parameters using Fanuc software and tools to ensure optimal performance.
