## 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)
