The common faults and their handling methods of electric actuators include the following:
1. Motor malfunction: Due to prolonged use or overload operation, the motor may overheat, causing an increase in rotor clearance and vibration, reducing output power until failure occurs. The handling method includes checking the power circuit and motor connection end, and replacing the motor if necessary.
2. Power failure: Power line failure, poor contact, or protection triggering issues may cause power failure. The handling method includes checking whether there is a short circuit or open circuit in the power line, cleaning the power contact points, and resetting the power protection device.
3. Transmission part malfunction: Damaged or loose hoses, connecting rods, or fittings in the transmission part may cause malfunctions. The handling method includes disassembling the body for inspection and repairing or replacing damaged components.
4. Mechanical failure: including internal component damage and external vibration issues. The processing method requires comprehensive diagnosis and analysis of the entire system, and the use of corresponding technologies and tools for maintenance.
5. Indicator light malfunction: If the power indicator light is not on or the signal is not working, it may be due to an open circuit in the fuse or a problem with the power supply of the servo board. The handling method includes checking the fuse and power indicator light, and replacing the indicator light if necessary.
6. Resistance and capacitance fault: If the actuator does not function properly after being powered on, it may be a problem with the resistance or capacitance. The handling method includes detecting resistors and capacitors, and replacing damaged components if necessary.
7. Motor overheating: Prolonged overload operation or poor heat dissipation may cause the motor to overheat. The handling method includes checking the motor load and cleaning the dust on the radiator to ensure good ventilation.
8. Slow or weak actuator action: This may be due to a mismatch in power supply voltage, motor damage, or gearbox issues. The handling method includes adjusting the power supply voltage, checking the motor winding and reducer teeth.
9. The actuator cannot start normally: insufficient power supply, incorrect control signals, or motor damage may cause the actuator to fail to start. The handling method includes checking the power circuit and voltage, ensuring the correct transmission of control signals, and replacing the motor if necessary.
10. Inaccurate position control: It may be due to a faulty position sensor or incorrect parameter settings. The processing methods include calibrating or replacing position sensors, and resetting control system parameters.
11. High vibration or noise of the actuator: It may be due to wear or poor assembly of the reducer. The handling method includes checking the wear of the reducer, replacing worn parts if necessary, and reassembling.
