Why MPL Servo Motors Fail:

 

Allen-Bradley MPL Servo Motor Repair

   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
