Common Servo Motor Failures
To ensure a successful servo motor repair, you need to be proficient in all areas of electro-mechanical repair and electronic repair.
Here are some common problems we see:
Mechanical Faults
- Bearings and bearing housings
- Grease, oil or cutting fluid contamination inside the motor
- Grease, oil or cutting fluid contamination inside the brake
- Shaft keyway or coupling failure
- Rotor magnet failures
- Out of balance rotors
- Motor brake wear
- Worn brushes or commutators (DC types)
- Carbon build up (DC types)
Electrical Faults
- Motor winding failures
- Brake coil failures
- Shorted wiring connections
- Broken wiring connections or faulty connectors
- Electromechanical tacho faults
Electronic Faults
- Encoder output or position count faults
- Encoder alignment
- Encoder Memory faults or corruption
- Electronic Tacho faults
- Memory battery failure
- Resolver failure
- Faulty components on PCB’s
- Op-amp failures
- Driver IC failures
