Braking Torque Formula
The following formula is used to calculate the Braking Torque.
Tb = TL + TI - TF
- Where Tb is the Braking Torque (N-m)
- TL is the total load torque (N-m)
- TI is the total inertia torque (N-m)
- TF is the total friction torque (N-m)
To calculate a braking torque, sum the load torque and the inertia torque, then subtract the total friction torque.
How to Calculate Braking Torque?
The following example problems outline how to calculate Braking Torque.
Example Problem #1
- First, determine the total load torque (N-m). In this example, the total load torque (N-m) is determined to be 50 .
- Next, determine the total inertia torque (N-m). For this problem, the total inertia torque (N-m) is measured to be 40 .
- Next, determine the total friction torque (N-m). In this case, the total friction torque (N-m) is found to be 70.
- Finally, calculate the Braking Torque using the formula above:
Tb = TL + TI – TF
Inserting the values from above and solving yields:
Tb = 50 + 40 – 70 = 20 (N-m)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
total load torque (N-m) = 8
total inertia torque (N-m) = 400
total friction torque (N-m) = 12
Enter these given values yields:
Tb = 8 + 400 – 12 = 396 (N-m)
