1. What is Hydraulic Motor Power?

Hydraulic motor power represents the mechanical power output of a hydraulic motor, calculated based on flow rate, pressure, and system efficiency. It's essential for proper motor selection and system design.

2. How Does the Calculator Work?

The calculator uses the hydraulic power formula:

Where:

• \( HP \) — Hydraulic power (horsepower)
• \( Q \) — Flow rate (gallons per minute, GPM)
• \( P \) — Pressure (pounds per square inch, PSI)
• \( \eta \) — System efficiency (0-1)

Explanation: The formula converts hydraulic energy (flow and pressure) to mechanical power, accounting for system efficiency losses.

3. Importance of Hydraulic Power Calculation

Details: Accurate power calculation ensures proper motor sizing, prevents system overload, and helps optimize energy efficiency in hydraulic systems.

4. Using the Calculator

Tips: Enter flow rate in GPM, pressure in PSI, and efficiency as a decimal (e.g., 85% = 0.85). Typical hydraulic systems have efficiencies between 0.8-0.95.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1714 used in the formula?
A: 1714 is the conversion factor that accounts for units (GPM, PSI) to result in horsepower.

Q2: What's a typical efficiency value?
A: Gear motors: 0.7-0.85, vane motors: 0.75-0.9, piston motors: 0.85-0.95.

Q3: How does temperature affect the calculation?
A: Higher temperatures may reduce efficiency due to increased fluid viscosity changes.

Q4: Can I use this for hydraulic pumps?
A: Yes, the same formula applies to pump input power calculations.

Q5: What if my pressure is in bar?
A: Convert bar to PSI (1 bar ≈ 14.5038 PSI) before using the calculator.
