Calculating Torque for Operating Multiple Agitators: Tips and Advice

[Eugym Fong]

Hi Guys and Girls, I new to here. I am Designer and recently I am studying the torque of a motor needed to turn a set of 20 agitators by using a belt. Let say each of the agitator have needed 2Nm to operate, so if I use a motor to operate 20 agitators how many of torque is needed. I have no idea on it. Can you give me some ideas? Thank you!

Hello Eugym, welcome to PF !

In the picture it says 5 Nm per agitator !
Anyway, in principle you can just add up the torques, so you would end up with 40 Nm for your case, or 100 Nm for the case as shown in the picture.

I also thinking in this way. Ok, I will try hard on it. Thanks for your opinion!

You also need to add sufficient torque to accelerate all of the rotational masses from 0 RPM within the time required. This will be in addition to the 20x5 Nm torque.
