How to calculate the output torque of servo planetary reducer

Is the power output of the planetary gearbox the same as that of the servo motor when the servo motor is connected to the reducer, and how is the output torque calculated,
The gearbox is just a transmission device! The function is to reduce speed while increasing torque! For example, if Yaskawa Electric is 400W, with a rated speed of 3000 revolutions per minute and a rated torque of 1.27Nm, and the reduction ratio of the gearbox is 1:10, then the overall output torque is 12.7Nm! The output speed is 300 revolutions per minute. That is to say, reducing the speed by a few times increases the torque by a few times!  

I am a manufacturer of servo planetary gearboxes, hoping to help you!

How to determine the power selection and calculation method of servo motors when using them on equipment

1、 Confirmation of rotational speed and encoder resolution.   

2、 Conversion of load torque on motor shaft and calculation of acceleration and deceleration torque.    

3、 Calculate the load inertia and match the inertia. Taking Yaskawa servo motors as an example, the inertia matching of some products can reach 50 times, but the smaller the actual value, the better for accuracy and response speed.    

4、 The calculation and selection of regenerative resistors, for servos, generally require external configuration for voltages above 2kw.    

5、 Cable selection, encoder cable twisted pair shielding, for Japanese products such as Yaskawa servo, the absolute encoder is 6-core, and the incremental encoder is 4-core. Power P=torque x angular velocity ω=F x velocity v
