1. What is the Hydraulic Motor Torque Formula?

The hydraulic motor torque formula calculates the torque output of a hydraulic motor based on system pressure, motor displacement, and rotational speed. This calculation is essential for designing and analyzing hydraulic systems.

2. How Does the Calculator Work?

The calculator uses the hydraulic motor torque formula:

\[ T = \frac{P \times V \times 1000}{2\pi \times N} \]

Where:

\( T \) — Torque (Nm)
\( P \) — Pressure (bar)
\( V \) — Displacement (cm³/rev)
\( N \) — Speed (rpm)

Explanation: The formula calculates the theoretical torque output of a hydraulic motor based on the input parameters. The 1000 factor converts cm³ to mm³ for proper unit consistency.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for selecting appropriate hydraulic motors, ensuring proper system performance, and preventing equipment failure due to insufficient torque output.

4. Using the Calculator

Tips: Enter pressure in bar, displacement in cm³/rev, and speed in rpm. All values must be valid positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is hydraulic motor displacement?
A: Displacement refers to the volume of fluid required to turn the motor output shaft through one complete revolution, measured in cm³/rev.

Q2: How does pressure affect torque output?
A: Torque is directly proportional to pressure - higher system pressure results in higher torque output from the hydraulic motor.

Q3: What is the relationship between speed and torque?
A: For a fixed displacement motor, torque decreases as speed increases when pressure remains constant, following an inverse relationship.

Q4: Are there efficiency factors to consider?
A: Yes, this formula provides theoretical torque. Actual torque will be lower due to mechanical and volumetric efficiencies of the motor.

Q5: Can this formula be used for all hydraulic motors?
A: This formula applies to fixed displacement hydraulic motors. Variable displacement motors require additional calculations based on their specific design.
