1. What is Hydraulic Motor Output Torque?

Hydraulic motor output torque is the rotational force produced by a hydraulic motor, calculated based on the motor's displacement and the system pressure. 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:

• \( T \) — Output torque (Nm)
• \( displacement \) — Hydraulic motor displacement (m³/rev)
• \( pressure \) — System pressure (Pa)
• \( \pi \) — Mathematical constant pi (approximately 3.1416)

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

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 torque for the intended application without overloading.

4. Using the Calculator

Tips: Enter displacement in m³/rev and pressure in Pa. Ensure both values are positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect hydraulic motor torque output?
A: The main factors are displacement (motor size) and system pressure. Efficiency losses due to friction and leakage also affect actual torque output.

Q2: How does displacement affect torque?
A: Larger displacement motors produce more torque at the same pressure, as they can handle more fluid volume per revolution.

Q3: What is the difference between theoretical and actual torque?
A: Theoretical torque is calculated from ideal conditions, while actual torque accounts for mechanical and volumetric efficiencies, which reduce the output.

Q4: Can this formula be used for all hydraulic motors?
A: This formula provides theoretical torque for most positive displacement hydraulic motors, but actual performance may vary based on motor type and efficiency.

Q5: How does pressure affect torque output?
A: Higher system pressure directly increases torque output, as torque is proportional to pressure in the torque equation.
