Common FANUC motor failures
The top eight common reasons for Fanuc Motor Failures.
| Electrical | Over time components break down. Therefore broken or faulty connections, short wiring etc. can be an issue. |
| Electronic | Encoder faults, memory battery failure, faulty components on the PCB. Liquid ingression due to coolants, oil, fluids and waters. |
| Moisture and Dirt | Contamination from oil and fluid can affect the bearings, the encoder, the electrics of the motor. Also the integrity of the windings. Moisture can cause component deterioration through rust. |
| Mechanical Faults | Out of balance rotors, shaft keyway or coupling failure and motor brake wear. All of these are causes of mechanical faults. |
| Improper Installation | If the belt is too tight or the positioning if off this can cause the motor to break down. |
| Bad Drive or Power Supply | A bad drive or power supply can cause a spike in voltage. As can introducing too high a current to a motor through human error. All this will cause damage to the drive. |
| Lack of Maintenance | Proper maintenance and applying a preventative maintenance plan can extend the lifespan of both components and the motor. |
| Overwork | Like everything in life the more it is overworked the shorter the lifespan! |
