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

Contents

The 1800 RPM, 1HP motor produces 3 ft. lbs of torque at 1800 RPM. The 3600 RPM, 1HP motor produces 1.5 ft.

## How much torque does a motor have?

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. Note! – the full torque from zero speed is a major advantage for electric vehicles.

## How do you calculate torque from horsepower?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

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

Multiply the horsepower by 5,252 using a calculator. Using the example figure, multiply 0.6434316 by 5,252 to get 3,379.3027. Divide the answer by the motor’s rated number of rpm to get the measurement of the torque in pound-feet.

## How do I calculate torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.

## Which is better hp or torque?

Horsepower is how rapidly the vehicle can perform that work. … Of course, horsepower is tied to torque mathematically. Horsepower equals torque multiplied by rpm, divided by a constant. Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.

## How much weight can a 1 hp motor lift?

Most engines use horsepower to describe how much work they can do in a given amount of time. The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.

## Do electric motors have more torque?

That’s possible because at lower speeds, electric motors deliver more torque than gas engines. “Torque is what you need to get a car going,” says Grace, and with more of it, electrics out-accelerate comparable gas engines.

3600 RPM

## What gives an electric motor torque?

Electric motors operate on three different physical principles: magnetism, electrostatics and piezoelectricity. In magnetic motors, magnetic fields are formed in both the rotor and the stator. The product between these two fields gives rise to a force, and thus a torque on the motor shaft.

0.738 lb/ft.

## What is the formula for net torque?

The minus sign indicates that the torque produces a clockwise rotation. Since the weight is the only force exerting a torque on the rod, then τnet = τMg = -Mg(L/2)cosθ.

## How do you calculate r in torque?

r is measured from the axis of rotation to the line of the force, and θ is the angle between r and F. The direction of the torque is given by the right-hand rule. Using your right hand, point your fingers in the direction of the first vector (r) and curl them into the direction of the second vector (F).
