## Hydraulic Motor Torque Formula

The following formula is used to calculate the Hydraulic Motor Torque.

Thm = P*d / (2*pi)

- Where Thm is the Hydraulic Motor Torque (lb-in)
- P is the pressure (psi)
- d is the displacement (in^3)

To calculate a hydraulic motor torque, multiply the pressure by the displacement, then divide by 2 times pi.

## How to Calculate Hydraulic Motor Torque?

The following two example problems outline how to calculate the Hydraulic Motor Torque.

**Example Problem #1:**

- First, determine the pressure (psi). In this example, the pressure (psi) is measured to be 500.
- Next, determine the displacement (in^3). For this problem, the displacement (in^3) is calculated to be .36.
- Finally, calculate the Hydraulic Motor Torque using the formula above:

Thm = P*d / (2*pi)

Inserting the values from above and solving the equation with the imputed values gives:

Thm = 500*.36 / (2*3.14159) = 28.647 (lb-in)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

pressure (psi) = 1250

displacement (in^3) = .75

Entering these values yields:

Thm = 1250*.75/ (2*3.14159) = 149.207 (lb-in)
