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

2. How Does The Calculator Work?

The calculator uses the hydraulic torque formula:

Where:

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

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

3. Importance Of Torque Calculation

Details: Accurate torque calculation is essential for selecting the appropriate hydraulic motor for an application, ensuring it can provide sufficient rotational force to drive the load.

4. Using The Calculator

Tips: Enter the motor displacement in cubic meters per revolution and system pressure in Pascals. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for displacement?
A: Displacement should be entered in cubic meters per revolution (m³/rev). For smaller motors, you may need to use cm³/rev and convert appropriately.

Q2: How do I convert between pressure units?
A: 1 bar = 100,000 Pa, 1 psi ≈ 6894.76 Pa, 1 MPa = 1,000,000 Pa. Make sure to convert your pressure reading to Pascals before calculation.

Q3: 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.

Q4: Can I use this for hydraulic pumps too?
A: While the principle is similar, this formula is specifically for hydraulic motors. For pumps, different considerations may apply.

Q5: What if I have torque in different units?
A: 1 Nm = 0.737562 lb-ft = 8.85075 lb-in. You can convert the result to your preferred torque units if needed.
