1. What is the Torque Equation?

The torque equation for hydraulic systems calculates the rotational force produced by a hydraulic motor based on its displacement and the system pressure. This is fundamental in hydraulic system design and analysis.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( Displacement \) — Hydraulic motor displacement in cubic meters per revolution (m³/rev)
• \( Pressure \) — System pressure in Pascals (Pa)
• \( \pi \) — Mathematical constant Pi (~3.1416)

Explanation: The equation relates the hydraulic motor's physical characteristics (displacement) and system pressure to the output torque.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for hydraulic system design, ensuring motors can provide sufficient rotational force for the application while operating within their pressure limits.

4. Using the Calculator

Tips: Enter displacement in m³/rev and pressure in Pa. Both values must be positive numbers. The result will be in Newton-meters (N·m).

5. Frequently Asked Questions (FAQ)

Q1: What is hydraulic motor displacement?
A: Displacement is the fluid volume required to turn the motor output shaft through one complete revolution.

Q2: How does pressure affect torque?
A: Torque is directly proportional to pressure - doubling the pressure doubles the torque output.

Q3: What are typical units for hydraulic calculations?
A: Common units are m³/rev for displacement, Pa or bar for pressure (1 bar = 100,000 Pa), and N·m for torque.

Q4: Can I use this for hydraulic pumps?
A: This equation works similarly for pumps, calculating the torque required to drive the pump at a given pressure.

Q5: What about efficiency losses?
A: This calculates theoretical torque. Actual torque may be less due to mechanical and volumetric efficiencies.
