Tips: Why Do Servo Motors Fail?
Servo motor failures often result from overheating, excessive vibration, poor lubrication, or incorrect wiring. To extend service life, ensure proper cooling, keep the motor clean and dry, and use a compatible driver with correct parameters. Regular maintenance and avoiding overload operation are key to keeping your servo motor running smoothly and reliably.
