1. What is Hydraulic Motor Torque?

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

• \( \tau \) — Output torque (N·m)
• \( P \) — System pressure (bar)
• \( V_g \) — Motor displacement (cm³/rev)
• \( \eta \) — Motor efficiency (0-1)

Explanation: The equation calculates the theoretical torque output of a hydraulic motor based on hydraulic pressure, motor size, and efficiency factor.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, system design, and ensuring the motor can handle the required mechanical load in hydraulic applications.

4. Using the Calculator

Tips: Enter pressure in bar, displacement in cm³/rev, and efficiency as a decimal between 0-1. All values must be positive numbers with efficiency between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical efficiency range for hydraulic motors?
A: Most hydraulic motors have efficiencies between 0.85-0.95 (85-95%), though this can vary based on motor type and operating conditions.

Q2: How does pressure affect torque output?
A: Torque is directly proportional to pressure - doubling the pressure doubles the torque output, assuming other factors remain constant.

Q3: What is motor displacement?
A: Displacement refers to the volume of fluid required to produce one complete revolution of the motor shaft, measured in cm³/rev.

Q4: Are there different types of hydraulic motors?
A: Yes, common types include gear motors, vane motors, and piston motors, each with different torque characteristics and efficiency profiles.

Q5: When should I consider mechanical efficiency?
A: Always account for efficiency in real-world applications as it affects the actual torque output and system performance.
