How to improve the service life of servo motors?

Servo motors are essential for many industrial applications because they offer excellent performance and accurate control. Maintaining operational effectiveness and reducing maintenance expenses necessitates optimizing servo motor life.

Servo motors play a key role in a variety of industrial applications, providing precise control and high performance. Maximizing servo motor life is critical to ensuring operational efficiency and minimizing maintenance costs. This article provides an in-depth look at the strategies and best practices necessary to increase the life of servo motors, covering key aspects such as proper installation, maintenance, environmental considerations, and operational best practices.

Understanding the importance of servo motor life

Servo motors are indispensable components in industrial automation, robotics, CNC machinery, and a variety of other applications. Their service life has a direct impact on the reliability and performance of these systems. Extending the life of servo motors not only reduces downtime and maintenance costs but also ensures consistent operational efficiency, ultimately contributing to increased productivity and cost-effectiveness.

Correct installation and commissioning

The basis for prolonging the service life of a servomotor begins with careful installation and commissioning. The manufacturer's guidelines and specifications must be followed during installation. This includes ensuring proper alignment, secure mounting, and proper wiring to mitigate mechanical stress and vibration. In addition, commissioning procedures should be performed accurately to verify that the motor is operating within specified parameters and under optimal conditions.

Effective maintenance practices

Regular and proactive maintenance is the basis for extending the service life of servo motors. This includes regular inspections to assess the condition of the motor, e.g. checking for wear and tear, loose connections, and signs of overheating. Lubrication of bearings and other moving parts should be carried out according to the manufacturer's recommendations. In addition, regular testing of the motor's performance and feedback devices (e.g., encoders) is essential for early detection of potential problems.

Operational environment considerations

The operating environment significantly affects the life of servo motors. Environmental factors such as temperature, humidity, dust, and corrosive elements can adversely affect motor performance and life. Measures to control the operating environment, such as proper ventilation, dust filtration, and environmental sealing, can greatly extend the life of a servo motor.

Other considerations

In addition to the above factors, there are some tips to extend the life of the servo motor is very helpful.

  1. Use of vibration isolation washers. A vibration isolation washer is a kind of important vibration isolation element, it is through the elastic material such as rubber, etc. in the motor and the mounting base between the buffer layer can effectively reduce the external vibration on the motor. In the installation of the motor, should be the first to avoid the vibration washer correctly set in the motor and the base of the corresponding mounting surface, to play its role of vibration avoidance. But at the same time do not use too much locking force, which may lead to the vibration isolation washer being too tight to produce uneven deformation, affecting its vibration isolation performance.
  2. Focus on bearing condition monitoring. Motor bearings are important wide temperature-sensitive parts, and their condition directly affects the service life of the motor. Therefore, you can regularly use the detector to check whether the bearings have abnormal noise and excessive temperature rise, and at the same time observe whether there is an oil leakage phenomenon. If you find any problem, according to the specific situation, you need to replace the bearings or replenish the lubricating oil in time to ensure that the temperature rise of the bearings operates within the specified safe temperature range.
  3. Reasonably select and fix the power supply voltage. Improper power supply voltage can also easily lead to motor problems. Unless there is extensive testing and verification, it is not recommended to adjust the rated voltage of the motor, to avoid overloading the motor or other dangers caused by too high or too low voltage.
  4. Clean the motor regularly. After running for a long time, a lot of dust will accumulate inside the motor, which will affect the ventilation and heat dissipation ability of the motor. You can regularly wipe the surface of the motor shell with a soft felt. The sealing end of the motor needs to be kept dry to prevent moisture invasion caused by the motor short circuit. If the working environment of the motor is poor, you can consider equipping the motor with a filter to prevent large particles from entering the motor.
  5. Use the motor correctly according to the standard. Starting and braking should also be carried out slowly by the specified procedures, prohibiting high-speed peak starting and stopping, so as not to bring shock damage to the motor components. During operation, the quality of the power supply needs to be monitored periodically to keep it within the permissible range.
  6. Use professional lubricants. When replacing the plastic gears in the motor section, choose a professional ceramic-based lubricant that protects the plastics and avoids the use of traditional mineral-based oils that may corrode the plastics.


In short, there are many aspects to consider to improve the service life of servo motors. We hope that the methods in this article will help you improve the operational reliability of your servo motors and maximize the life of your motors.
