# Frequent question: How much torque does a 1 hp electric motor have?

Contents

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.

## What is the torque of an electric motor?

The driving force of an electric motor is torque – not horsepower. The torque is the twisting force that makes the motor running and the torque is active from 0% to 100% operating speed.

## How do you calculate the torque of an electric motor?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

## How much torque does 1 HP have?

The definition of 1 Horsepower is displacing 1 lb. 33,000 ft. in one minute or 33,000 lb-ft / minute.

## How fast will 1HP go?

1hp=550 ft-lbs/sec, so will get a forward force of 30 pounds. Since you are 172 pounds, this gets you an acceleration of 0.17 g, or 5.6 ft/s/s. IOW it will take 3 or 4 seconds to reach 12 mph.

## Why do electric cars get instant torque?

As the electric current travels through the motor within a magnetic field, it generates a force. The more current applied, the more the motor will spin. … But at zero RPM, all of the electricity the motor creates from the time electric power is applied becomes instant torque—without any back EMF to reduce its output.

## Do electric motors have more torque?

Electric vehicles generate much more torque than gas vehicles, which is important because torque is what drives the vehicle forward. Furthermore, an electric car’s motor eliminates the need for a traditional transmission in many modern designs.

## What is torque in AC motor?

Torque: The torque output of a motor is the amount of rotational force that the motor develops. The torque of a small electric motor is commonly measured in either inch pounds (in-lbs), Newton meters (N-m) or other directly converted units of measure.

## 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.

## 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 kW is a 1 hp motor?

Horsepower (metric) to Kilowatt Conversion Table

Horsepower (metric) Kilowatt [kW]
1 horsepower (metric) 0.73549875 kW
2 horsepower (metric) 1.4709975 kW
3 horsepower (metric) 2.20649625 kW
5 horsepower (metric) 3.67749375 kW

## Why is HP 5252?

5,252 is a fix it factor for those wanting to use Power in horse power, torque in foot pounds and rotation in revolutions per minute. Instantaneous power (the power at a given instant) is equal to torque times “revs” but you have to use torque in Newton meters and revs in radians per second, for an answer in Watts.
