## Required Torque Formula

The following formula is used to calculate the Required Torque.

**Tr eq = (LT + AT) * SF**

- Where Treq is the Required Torque (N-m)
- LT is the load torque (N-m)
- AT is the acceleration torque (N-m)
- SF is the safety factor

## How to Calculate Required Torque?

The following example problems outline how to calculate the Required Torque.

**Example Problem #1**

- First, determine the load torque (N-m). In this example, the load torque (N-m) is given as 13 .
- Next, determine the acceleration torque (N-m). For this problem, the acceleration torque (N-m) is given as 50 .
- Next, determine the safety factor. In this case, the safety factor is found to be 2.
- Finally, calculate the Required Torque using the formula above:

Tr eq = (LT + AT) * SF

Inserting the values from above and solving yields:

Tr eq = (13 + 50) * 2 = 126 (N-m)

**Example Problem #2**

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

load torque (N-m) = 500

acceleration torque (N-m) = 9

safety factor = 3.5

Enter these given values yields:

Tr eq = LT + AT * SF = 1781.5** **(N-m)
