1. What is Hydraulic Motor Torque?

Hydraulic motor torque is the rotational force produced by a hydraulic motor, calculated based on the motor's displacement and the system pressure. It's a critical parameter in hydraulic system design and performance evaluation.

2. How Does the Calculator Work?

The calculator uses the hydraulic torque equation:

Where:

• \( T \) — Torque (Nm)
• \( displacement \) — Motor displacement (m³/rev)
• \( pressure \) — System pressure (Pa)
• \( \pi \) — Mathematical constant (approximately 3.1416)

Explanation: This formula calculates the theoretical torque output of a hydraulic motor based on its physical displacement characteristics and the system pressure.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper hydraulic system design, motor selection, and ensuring that the motor can provide sufficient rotational force for the intended application.

4. Using the Calculator

Tips: Enter displacement in m³/rev and pressure in Pascals (Pa). Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

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

Q2: How does pressure affect torque?
A: Torque is directly proportional to pressure - higher system pressure results in higher torque output from the hydraulic motor.

Q3: What are typical units for hydraulic torque?
A: Torque is typically measured in Newton-meters (Nm) or pound-feet (lb-ft) in imperial systems.

Q4: Is this the actual or theoretical torque?
A: This formula calculates theoretical torque. Actual torque may be slightly lower due to mechanical efficiency losses in the motor.

Q5: Can this formula be used for all hydraulic motors?
A: This formula applies to most positive displacement hydraulic motors, but specific motor designs may have slightly different characteristics.
