Hydraulic Motor Displacement Calculator

Formula

The formula to calculate the hydraulic motor displacement is:

$HMD = \frac{T \cdot 2\pi}{P}$

Where:

$HMD$ is the Hydraulic Motor Displacement (in³)
$T$ is the motor torque (in-lbs)
$P$ is the motor pressure (PSI)

What is Hydraulic Motor Displacement?

Hydraulic motor displacement refers to the volume of fluid required to turn the motor through one revolution. It is a key parameter in determining the motor's performance and efficiency.

Example

Let's say the motor torque (T) is 500 in-lbs, and the motor pressure (P) is 1500 PSI. Using the formula:

$HMD = \frac{500 \cdot 2\pi}{1500} \approx 2.0944 \text{ in³}$

So, the hydraulic motor displacement (HMD) is approximately 2.0944 in³.
