Servo motor is a high-precision, high-control performance motor that is widely used in CNC machine tools, semiconductor equipment, robots, automated production lines and other fields. Servo motors have very high accuracy requirements, so they usually need to be matched with a high-precision reducer to optimize motion accuracy. Planetary reducer is one of the most commonly used reducers for servo motors. It has the characteristics of simple structure, light weight, high efficiency, large torque, high precision and low noise. The following will introduce how to choose a suitable planetary reducer based on the characteristics of the servo motor.
When choosing a reducer when the servo motor is known, you generally need to understand the following two points. The first point is that low-power servo motors can be used with large reducers, but high-power motors cannot be used with small reducers; the second point is that under the same specifications, reducers with high rigidity will be of better quality. In addition, the matching of servo motor and reducer also needs to consider these four dimensions: torque, speed, accuracy, and stability. The first is the size of the torque. During the application process of the servo motor, the required torque is determined based on the actual workload. When selecting a planetary reducer, you should choose a planetary reducer that matches the torque of the servo motor to achieve the optimal power transmission effect. It should be noted that during the process of transmitting power, the planetary reducer should be able to withstand the impact force generated during acceleration and deceleration. The second is the reduction ratio. The working speed and torque of the servo motor have a certain relationship with the output rotation speed and torque. The reduction ratio of the planetary reducer can match the output rotation speed and torque with the torque and speed of the servo motor. Therefore, when selecting a planetary reducer, the required reduction ratio must be determined based on the parameters of the servo motor to achieve the ideal control effect. Then there is the stability of the motor. During the application process, the servo motor often needs to work continuously for a long time. Therefore, the planetary reducer should have sufficient stability and reliability to ensure the normal operation of the device. It is necessary to choose a planetary reducer with high reliability, long life and excellent cost performance to ensure the long-term stable operation of the device. The last is the accuracy requirement. During the application process of the servo motor, it is necessary to achieve high-precision control. Technical indicators such as the reduction ratio of the planetary reducer and the accuracy of the gear rotation will have an impact on the accuracy of the servo motor. Therefore, when selecting a planetary reducer, a high-precision planetary reducer should be selected according to the accuracy requirements of the servo motor .
