# How do you calculate motor torque from RPM?

Contents

To calculate torque from RPM, use this formula: Torque = (Motor Horsepower) x 63025 x Service Factor / RPM.

## How do you calculate torque from HP and RPM?

When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.

## What is the torque at 2000 RPM?

Torque and acceleration

rpm Torque engine 2nd gear (2.534 : 1)
2000 440 Nm 1114 Nm
2500 470 Nm 1190 Nm
3000 500 Nm 1267 Nm
3500 530 Nm 1343 Nm

## How much torque does a 1 hp motor have?

The 3600 RPM, 1HP motor produces 1.5 ft. lbs. of torque at 3600 RPM. So if your 1HP pump was operating at 1800 RPM, the 1800 RPM motor would be producing 3 ft.

## How many HP is RPM?

In other words, power is the rate of completing work (or applying torque) in a given amount of time. Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe.

## How many ft lbs is 1 HP?

1 horsepower (hp) = 550.00 foot pounds per second (ft-lb/sec)

## Which is better torque at low RPM or torque at high RPM?

Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower.

## Does torque increase with speed?

Here’s what you need to know about torque: Torque is a measure of rotating force. Engines create torque as they turn. Torque rises with engine speed to a point, then falls off again.
