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 do you calculate maximum torque of a motor?

Calculate torque (T) using the formula **T = 5,252 x horsepower/rpm**. The results are measured in pound-feet. For example, if you have a 40-horsepower motor designed to operate at a peak of 1,200 rpm, the formula would be T = (5,252 x 40)/1200 = 175.07 lb.

## How do you calculate torque load?

Load Torque ( T )

Load torque is very simple. As you see this equation torque is the product of the force and the distance between the force and the center of rotation. For example, if you want to hold the force acting on the end of pulley, **T = F x r.**

## What is the torque of a DC motor?

Torque equation of a DC motor

When armature conductors of a DC motor carry current in the presence of stator field flux, a mechanical torque is developed between the armature and the stator. Torque **is given by the product of the force and the radius at which this force acts**.

## 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 much torque is required to move a car?

Overall transmission (and power-train) efficiency of the modern electric vehicles is within 59 .. 62 %. The answer to your question is **43.2 Nm** of Torque required that can be obtained with the transmission ratio value of 15.

## What are the components of load torque?

**Components of load torques:**

- Friction Torque (TF) The friction torque (TF) is the equivalent value of various friction torques referred to the motor shaft.
- Windage Torque (Tw) When a motor runs, the wind generates a torque opposing the motion . …
- Torque required to do useful mechanical work ( Tm)

## How much torque do I need?

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.
