Problem & answerB-13
Powder Feeder Motor Failure
Likely causes
- Motor overload
- Electrical failure or loose wiring
- Worn bearings
- PLC output fault
- Mechanical seizure
How to fix it
- 1Stop the machine immediately and apply lockout/tagout.
- 2Inspect the motor for overheating, unusual noise or damage.
- 3Check power supply, fuses and wiring.
- 4Verify the PLC output to the motor.
- 5Inspect bearings and drive couplings.
- 6Repair or replace the motor; carry out a functional test before production.
It is fixed when
Motor runs smoothly without overheating and powder feed remains stable during a trial run.
Stop it coming back
- Inspect motors routinely, keep connections tight, lubricate bearings and monitor motor temperature on long runs.
