Motor 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 do work and is a critical parameter in determining a vehicle's towing capacity, acceleration, and overall performance.
The calculator uses the motor torque formula:
Where:
Explanation: The constant 5252 is derived from the relationship between horsepower, torque, and RPM. This formula shows that torque and horsepower are always equal at 5252 RPM in the imperial measurement system.
Details: Calculating motor torque is essential for engine design, vehicle performance analysis, mechanical system design, and understanding the power characteristics of motors and engines in various applications.
Tips: Enter horsepower and RPM values. Both values must be positive numbers greater than zero for accurate calculation.
Q1: Why is 5252 used in the torque formula?
A: 5252 is a constant derived from the relationship between foot-pounds, horsepower, and RPM. It's the RPM at which horsepower and torque values are equal in the imperial measurement system.
Q2: 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 = (Torque × RPM) / 5252.
Q3: How does torque affect vehicle performance?
A: Higher torque generally means better acceleration and towing capacity, especially at lower RPMs. Diesel engines typically produce more torque than gasoline engines.
Q4: Can I use this formula for electric motors?
A: Yes, the formula works for any rotational power system, including electric motors, internal combustion engines, and turbines.
Q5: How is torque measured in different unit systems?
A: In the metric system, torque is typically measured in Newton-meters (N·m). The conversion factor is 1 lb-ft = 1.35582 N·m.
