1. What is Hydraulic Wheel Motor Torque?

Hydraulic wheel 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 crucial parameter for determining the motor's ability to perform work.

2. How Does the Calculator Work?

The calculator uses the fundamental torque equation for hydraulic motors:

Where:

• \( Displacement \) — Motor displacement per revolution (m³/rev)
• \( Pressure \) — Pressure difference across the motor (Pa)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The equation shows that torque is directly proportional to both displacement and pressure, with the result divided by 2π to convert to Newton-meters.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for selecting the right hydraulic motor for an application, ensuring it can provide sufficient force to move the load while operating within its design limits.

4. Using the Calculator

Tips: Enter displacement in cubic meters per revolution (m³/rev) and pressure in Pascals (Pa). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical displacement for wheel motors?
A: Wheel motor displacements typically range from 0.0001 to 0.001 m³/rev (100-1000 cm³/rev), depending on application.

Q2: How does pressure affect torque?
A: Torque is directly proportional to pressure. Doubling the pressure will double the torque output.

Q3: What's the difference between theoretical and actual torque?
A: This calculator gives theoretical torque. Actual torque will be slightly less due to mechanical losses (typically 85-95% of theoretical).

Q4: Can this be used for all hydraulic motors?
A: Yes, this fundamental equation applies to gear, vane, and piston motors, though efficiency factors may differ.

Q5: How to increase torque output?
A: Either increase system pressure or use a motor with greater displacement, within system design limits.
