Enter the total load torque (N-m), the total inertia torque (N-m), and the total friction torque (N-m) into the calculator to determine the Braking Torque.

## 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)

## How to Calculate Braking Torque?

The following example problems outline how to calculate Braking Torque.

Example Problem #1

1. First, determine the total load torque (N-m). In this example, the total load torque (N-m) is determined to be 50 .
2. Next, determine the total inertia torque (N-m). For this problem, the total inertia torque (N-m) is measured to be 40 .
3. Next, determine the total friction torque (N-m). In this case, the total friction torque (N-m) is found to be 70.
4. 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)
