Enter the armature torque (N-m) and the shaft torque (N-m) into the Calculator. The calculator will evaluate the Torque Loss. 

Torque Loss Formula

TL = AT - ST

Variables:

  • TL is the Torque Loss (N-m)
  • AT is the armature torque (N-m)
  • ST is the shaft torque (N-m)

To calculate Torque Loss, subtract the shaft torque from the armature torque.

How to Calculate Torque Loss?

The following steps outline how to calculate the Torque Loss.


  1. First, determine the armature torque (N-m). 
  2. Next, determine the shaft torque (N-m). 
  3. Next, gather the formula from above = TL = AT – ST.
  4. Finally, calculate the Torque Loss.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

armature torque (N-m) = 100

shaft torque (N-m) = 200
