Torque Formula:
| From: | To: |
Motor torque is a measure of the rotational force produced by an engine or motor. It represents the engine's ability to perform 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 comes from the relationship between horsepower, torque, and RPM. This formula calculates the torque output based on the horsepower and rotational speed of the motor.
Details: Torque calculation is essential for understanding engine performance, vehicle acceleration capabilities, and determining the appropriate motor for specific applications. It helps in selecting the right motor for industrial equipment, vehicles, and mechanical systems.
Tips: Enter horsepower and RPM values. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the relationship between torque and horsepower?
A: Horsepower is calculated from torque and RPM (HP = Torque × RPM ÷ 5252). They are related but measure different aspects of engine performance.
Q2: Why is 5252 used in the formula?
A: 5252 is a constant derived from the relationship between foot-pounds, minutes, and horsepower. It's the RPM at which torque and horsepower values are equal.
Q3: What are typical torque values for different engines?
A: Torque values vary significantly by engine type. Small car engines might produce 100-200 lb-ft, while diesel truck engines can produce 800-1000+ lb-ft.
Q4: How does torque affect vehicle performance?
A: Higher torque generally means better acceleration and towing capacity. Diesel engines typically have higher torque at lower RPMs than gasoline engines.
Q5: Can this formula be used for electric motors?
A: Yes, the same formula applies to electric motors, though electric motors often have different torque characteristics (maximum torque at zero RPM).
