The Challenge
The affected axis could not position accurately and the machine was unable to maintain a stable production cycle.
Diagnosis
- The motor was inspected for bearing condition, winding balance, insulation, encoder or resolver feedback, brake operation, shaft condition, contamination, and mechanical alignment.
Our Solution
- The motor was dismantled, cleaned, and repaired as required. Bearings, feedback components, seals, brake parts, or winding-related issues were addressed where applicable, followed by alignment and functional testing.
1. BEFORE
2. DISASSEMBLY
3. INSPECTION
4. FUNCTIONAL TESTING
Testing Performed
- Winding resistance test; insulation test; bearing/shaft check; encoder or resolver signal test; brake test where fitted; rotation test; vibration and temperature monitoring.
Final Result
The reference repair process restores normal functional operation after the unit passes the defined electrical, communication, motion, or load checks applicable to the equipment.
Common Fault Codes & Causes
- No native fault code is generated by the motor itself; alarm codes are normally reported by the connected servo drive/controller. Common failure causes: Bearing wear; encoder contamination or misalignment; cable faults; overheating; brake wear; moisture; mechanical overload.
Preventive Maintenance
- Monitor bearing noise and temperature, keep connectors and feedback cables protected, prevent mechanical overload, maintain correct alignment, and react quickly to encoder or brake alarms.
