Discussion Overview

The discussion revolves around calculating the torque required for a motor to operate multiple agitators, specifically focusing on a scenario with 20 agitators. Participants explore the principles of torque addition and the need to consider acceleration in their calculations.

Discussion Character

  • Technical explanation, Mathematical reasoning, Debate/contested

Main Points Raised

  • One participant states that each agitator requires 2 Nm of torque, leading to a total of 40 Nm for 20 agitators, while another mentions a different requirement of 5 Nm per agitator, suggesting a total of 100 Nm.
  • Some participants propose that the total torque must also account for the torque needed to accelerate the rotational masses from 0 RPM, indicating that this would add to the calculated torque based on the number of agitators.

Areas of Agreement / Disagreement

Participants express differing views on the torque requirements per agitator, leading to multiple competing calculations. The need to include acceleration in the torque calculation is also a point of discussion, indicating that the topic remains unresolved.

Contextual Notes

There are assumptions regarding the torque values per agitator, which are not universally agreed upon. Additionally, the discussion does not clarify the time frame for acceleration or the specifics of the rotational masses involved.

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 :smile: !

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.
