Servo motor is a kind of high performance drive device widely used in modern industry, but in the process of use, we sometimes face the problem of overheating servo motor. So, why are the servo motors overheating? How to solve this problem? This article will analyze these problems in depth to help you better deal with the problem of servo motor overheating.
There are many main reasons for servo motor overheating. Excessive load is one of the common causes of overheating of servo motors. When the load exceeds the rated carrying capacity of the motor, the motor needs to invest more power in the operation, which generates more heat, resulting in overheating of the motor. Phase loss is another factor that causes the servo motor to overheat. The missing phase causes the motor to fail to operate normally, which causes it to generate abnormal heat during operation. In addition, factors such as air duct obstruction, low speed operation time is too long and power supply harmonics are too large will also affect the heat dissipation effect of the servo motor, resulting in overheating problems.
In order to reduce the heat of the servo motor, we need to reduce the copper loss and iron loss of the motor. Methods to reduce copper loss include reducing the resistance and current of the motor. When choosing a motor, we should try to choose a motor with a smaller rated current, and try to use a series motor rather than a parallel motor to reduce current and power. However, this often requires a trade-off between torque and high speed requirements. For selected motors, we can also take full advantage of the driver’s automatic half-current control and off-line functions. The former can automatically reduce the current when the motor is at static, and the latter can cut off the current to effectively reduce the heat of the servo motor.
In practical applications, we also need to comprehensively consider the working environment and operating requirements of the servo motor, and reasonably choose a combination of the motor and the driver to improve the overall efficiency and stability of the system. In addition, regularly checking the cooling system of the servo motor to ensure that the air duct is smooth is also the key to preventing overheating problems.
Servo motor overheating problem is not unsolvable. By reasonable selection of motors and drives, reducing load, maintaining a good heat dissipation environment and other measures, we can effectively solve the problem of servo motor overheating, improve the stability and efficiency of industrial production. Let us meet this challenge together, so that servo motors play a greater role in modern industry, driving the vigorous development of intelligent manufacturing.
