The abnormal noise of servo motors can be caused by various reasons, and the following are some common reasons:

motor

Bearing wear: Bearings in servo motors may wear out due to prolonged or improper use, resulting in abnormal noises. When bearings wear out, metal friction sound and noise will be generated, and bearings need to be replaced to solve the problem.

 

Gear damage: The gears in the servo motor may be damaged due to prolonged use or overload, resulting in abnormal noises. When the gear is damaged, it will produce metal impact sound and noise, and the gear needs to be replaced to solve the problem.

 

Motor magnetic field interference: Motor magnetic field interference may also cause abnormal noise in servo motors. When the magnetic field of the motor interferes with other equipment or signals, it will produce noise and abnormal noise. The problem can be solved by increasing shielding or reducing the motor magnetic field.

 

Motor positioning accuracy: When the positioning accuracy of the servo motor is not high enough, it can cause motor vibration and abnormal noise. The problem can be solved by adjusting motor parameters and improving motor control accuracy.

 

Unstable power supply voltage: Unstable power supply voltage may also cause abnormal noise in the servo motor. When the power supply voltage fluctuates significantly, it will have an impact on the operation of the motor, leading to noise and abnormal noise. The problem can be solved by adding a power filter or using a regulated power supply. In summary, there are many reasons for abnormal noise in servo motors, which need to be investigated and resolved according to specific circumstances. When troubleshooting problems, it is necessary to pay attention to safety and avoid causing harm to equipment and personnel.

      If there is no problem with the load and there is no overload, the abnormal noise of the servo motor may be due to improper rigidity adjustment or improper gain adjustment.
Servo motor refers to the engine that controls the operation of mechanical components in a servo system, and is an indirect variable speed device that supplements the motor. Servo motors can control speed and position accuracy very accurately, and can convert voltage signals into torque and speed to drive the controlled object.
DC servo motors can be applied in spark machines, robotic arms, precision machines, etc. It can be equipped with a 2500P/R high resolution standard encoder and tachometer at the same time, and can be equipped with a gearbox to bring reliable accuracy and high torque to mechanical equipment. Good speed regulation, with the highest output power per unit weight and volume, greater than AC motors and far exceeding stepper motors. The torque fluctuation of multi-level structures is small.
The servo motor is used in a closed loop. That is to say, it transmits signals to the system at any time, and at the same time corrects its operation by using the signals provided by the system. Servo motors can also be controlled by microcontrollers.
