How to Choose Suitable Servo Planetary Reducer

- Jan 18, 2021-

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


The ideal reduction ratio calculation formula: reduction ratio = servo motor speed / planetary gear reducer output shaft speed


Torque calculation: For the service life of the servo planetary reducer, the torque calculation is very important. People should pay attention to whether the maximum torque value (TP) of acceleration exceeds the maximum load torque of the planetary gear reducer or not.


Servo planetary reducer model selection and precautions: the applicable power is usually the applicable power of the servo models on the market. The applicability of planetary gear reducers is very high, and the working coefficient can be maintained at 1.2 above, but users can also determine according to own needs during selection:


1. The output shaft diameter of the selected servo motor cannot be greater than the specified maximum shaft diameter.


2. Base on the calculation via the torque, if the working speed can meet the normal operation while there is insufficiency during full output of the servo, we can make current limiting control on the motor side driver, or make torque protection on the mechanical shaft, which is very necessary.
