Torque Formula:
| From: | To: |
The torque calculation for hydraulic motors determines the rotational force output based on system pressure and motor displacement. This is essential for proper hydraulic system design and component selection.
The calculator uses the torque formula:
Where:
Explanation: The formula calculates the theoretical torque output of a hydraulic motor based on the pressure difference across the motor and its displacement volume.
Details: Accurate torque calculation is crucial for selecting appropriate hydraulic motors, ensuring proper system performance, and preventing component failure due to insufficient torque capacity.
Tips: Enter pressure in Pascals (Pa) and volume displacement in cubic meters per revolution (m³/rev). Both values must be positive numbers.
Q1: What is the significance of 2π in the formula?
A: The 2π factor converts the work done per revolution into torque, as torque is work per radian and there are 2π radians in one revolution.
Q2: How does motor efficiency affect actual torque output?
A: Actual torque output will be lower than theoretical due to mechanical and volumetric losses. Typical hydraulic motor efficiencies range from 80-95%.
Q3: Can this formula be used for all types of hydraulic motors?
A: This formula applies to ideal hydraulic motors. Actual performance may vary based on motor type (gear, vane, piston) and design characteristics.
Q4: What are typical torque values for hydraulic motors?
A: Torque values vary widely based on motor size and pressure rating, ranging from a few Nm for small motors to thousands of Nm for large industrial motors.
Q5: How does system pressure affect torque output?
A: Torque is directly proportional to pressure. Doubling the pressure will double the torque output, assuming constant displacement.
