1. What is the Hydraulic Motor Torque Formula?

The hydraulic motor torque formula calculates the theoretical torque output of a hydraulic motor based on system pressure and motor displacement. It's a fundamental equation in hydraulic system design and analysis.

2. How Does the Calculator Work?

The calculator uses the hydraulic motor torque formula:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Pressure (Pa)
• \( V \) — Displacement volume (m³/rev)
• \( 2\pi \) — Conversion factor from work to torque

Explanation: The formula derives from the relationship between hydraulic power and mechanical power, where pressure times flow equals torque times angular velocity.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper hydraulic motor selection, system design, and ensuring the motor can handle the required mechanical load without stalling or overheating.

4. Using the Calculator

Tips: Enter pressure in Pascals (Pa) and displacement volume in cubic meters per revolution (m³/rev). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for pressure and displacement?
A: Pressure should be in Pascals (Pa) and displacement in cubic meters per revolution (m³/rev) for accurate results in Newton-meters (Nm).

Q2: Is this the actual or theoretical torque?
A: This calculates theoretical torque. Actual torque may be lower due to mechanical efficiency losses, friction, and other factors.

Q3: How does motor efficiency affect torque output?
A: Mechanical efficiency reduces actual torque output. Multiply theoretical torque by mechanical efficiency to get actual torque.

Q4: Can I use different pressure units?
A: Yes, but you must convert to Pascals first (1 bar = 100,000 Pa, 1 psi = 6894.76 Pa).

Q5: What if my displacement is in different units?
A: Convert to m³/rev (1 cm³/rev = 0.000001 m³/rev, 1 in³/rev = 0.0000163871 m³/rev).
