## Hydraulic Motor Displacement Formula

The following two example problems outline the steps and information needed to calculate the Hydraulic Motor Displacement.

HMD = T * 2*pi / P

Variables:

- HMD is the Hydraulic Motor Displacement (in^3)
- P is the motor pressure (PSI)
- T is the motor torque (in-lbs)

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

## How to Calculate Hydraulic Motor Displacement?

The following steps outline how to calculate the Hydraulic Motor Displacement.

- First, determine the motor pressure (PSI).
- Next, determine the motor torque (in-lbs).
- Next, gather the formula from above = HMD = T * 2*pi / P.
- Finally, calculate the Hydraulic Motor Displacement.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

motor pressure (PSI) = 30

motor torque (in-lbs) = 50

HMD = T * 2*pi / P** **= ?
