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 work and overcome resistance.

2. How Does the Calculator Work?

The calculator uses the hydraulic motor 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 selecting appropriate hydraulic motors for specific applications, ensuring they can provide sufficient force to drive the intended 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 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 formula calculates theoretical torque. Actual torque may be slightly lower due to efficiency losses in the motor.

Q3: How does motor efficiency affect torque?
A: Motor efficiency typically ranges from 80-95%. To find actual torque, multiply the theoretical torque by the motor's mechanical efficiency.

Q4: Can I use different pressure units?
A: Yes, but you'll need to convert them to Pascals (1 bar = 100,000 Pa, 1 psi = 6,894.76 Pa).

Q5: What if I know the torque and need to find pressure or volume?
A: The formula can be rearranged: P = (T × 2π) / V or V = (T × 2π) / P.
