1. What is Hydraulic Motor Torque?

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

2. How Does the Calculator Work?

The calculator uses the hydraulic motor torque equation:

Where:

• \( T \) — Torque (Newton-meters)
• \( P \) — Pressure (Pascals)
• \( V \) — Displacement volume (cubic meters per revolution)
• \( 2\pi \) — Constant (approximately 6.2832)

Explanation: The equation calculates the theoretical torque output based on hydraulic pressure and motor displacement, considering the conversion from linear to rotational force.

3. Importance of Torque Calculation

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

4. Using the Calculator

Tips: Enter pressure in Pascals and displacement volume in cubic meters per revolution. Both values must be positive numbers for accurate calculation.

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.

Q2: Is this the theoretical or actual torque?
A: This calculates theoretical torque. Actual torque may vary due to mechanical efficiency, friction losses, and other factors in real-world applications.

Q3: 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).

Q4: What affects hydraulic motor torque output?
A: Torque is primarily determined by system pressure and motor displacement, but also affected by efficiency, temperature, and fluid properties.

Q5: How does torque relate to hydraulic motor power?
A: Power = Torque × Angular Velocity. Higher torque at the same speed means higher power output.
