Why MPL Servo Motors Fail:

MPL servo motors are reliable but frequently face issues due to:
- Encoder misalignment or signal loss
- Shaft wobble or broken bearings
- Brake not holding or slipping
- Motor overheating or phase imbalance
- Internal contamination (oil/dust ingress)
- Coil burn or insulation failure
These issues result in vibration, drive alarms, or total axis failure – impacting your production lines
