1. What is Hydraulic Motor Torque?

Hydraulic motor torque is the rotational force produced by a hydraulic motor, calculated based on system pressure and the motor's displacement volume. It represents the motor's ability to perform work and overcome resistance.

2. How Does the Calculator Work?

The calculator uses the hydraulic torque equation:

Where:

• \( T \) — Torque (Nm)
• \( P \) — Pressure (Pa)
• \( V \) — Displacement volume (m³/rev)
• \( 2\pi \) — Constant (approximately 6.2832)

Explanation: The equation calculates the theoretical torque output of a hydraulic motor based on the pressure difference across the motor and its displacement per revolution.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper hydraulic system design, motor selection, and ensuring the system can provide sufficient power for the intended application without overloading components.

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 greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for pressure and volume?
A: Pressure should be in Pascals (Pa) and displacement volume 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 slightly lower due to efficiency losses, mechanical friction, and other factors in real-world applications.

Q3: Can I use different pressure units?
A: Yes, but you'll need to convert to Pascals first. 1 bar = 100,000 Pa, 1 psi = 6,894.76 Pa, 1 MPa = 1,000,000 Pa.

Q4: What is displacement volume?
A: Displacement volume is the fluid volume required to produce one complete revolution of the hydraulic motor, typically provided in the motor specifications.

Q5: How does efficiency affect torque output?
A: Actual torque output is theoretical torque multiplied by mechanical efficiency. Most hydraulic motors have mechanical efficiencies between 85-95%.
