Motor Torque Formula:
From: | To: |
Torque is a measure of the rotational force produced by a motor. It represents the motor's ability to do work and is typically measured in pound-feet (lb-ft) or Newton-meters (N·m).
The calculator uses the torque formula:
Where:
Explanation: The constant 5252 is derived from the relationship between horsepower, torque, and RPM, where 1 horsepower is defined as 550 foot-pounds per second.
Details: Calculating torque is essential for selecting appropriate motors for specific applications, determining mechanical advantage in gear systems, and ensuring proper performance in automotive and industrial applications.
Tips: Enter horsepower and RPM values. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What's the difference between torque and horsepower?
A: Torque is a measure of rotational force, while horsepower is a measure of work done over time. Horsepower equals torque multiplied by RPM divided by 5252.
Q2: Why is 5252 used in the formula?
A: 5252 is the constant that results from the conversion between different units of measurement, specifically relating foot-pounds, minutes, and seconds in the definition of horsepower.
Q3: Can I use this formula for electric motors?
A: Yes, this formula applies to all types of motors as long as you have accurate horsepower and RPM measurements.
Q4: How does gear reduction affect torque?
A: Gear reduction increases output torque while decreasing output speed, maintaining the same power (assuming no efficiency losses).
Q5: What are typical torque values for different motors?
A: Torque values vary significantly based on motor size and type. Small electric motors might produce a few lb-ft of torque, while large diesel engines can produce over 1000 lb-ft.
