How to Select The Servo Planetary Reducer Reasonably

- Jan 25, 2021-

The servo planetary reducer needs to be adapted to the motor to work effectively, reducing the motor speed and increasing the output torque. So, how should the servo planetary reducer be selected reasonably? Gigager engineer suggests that try to select the servo planetary reducer close to ideal reduction ratio as much as possible.


Ideal reduction ratio calculation formula: reduction ratio = servo motor speed / output shaft speed of the planetary gear reducer


Torque calculation: For the service life of the servo planetary reducer, the torque calculation is very important, and it is necessary to pay attention to whether the maximum torque value (TP) of acceleration exceeds the maximum load torque of the planetary gear reducer.


Cautions for selection of servo planetary reducer:

1. The applicable power is usually the applicable power of the servo models on the market. The planetary gear reducer has a high applicability and the working coefficient can be maintained above 1.2, however it can also be determined by user’s needs.


2. The output shaft diameter of the selected servo motor cannot be bigger than the maximum shaft diameter of the table.


3. The speed can meet normal operation base on torque calculation. But if power is insufficient when servo is in full output, it is necessary to use the driver on the motor side to limit current , or to perform torque protection on the mechanical shaft.
