What is a torque curve?

plots the torque of a motor against the speed the motor is going at. The relationship between speed and torque varies dramatically across different types of motor and also between manufacturers.

How do you calculate the torque of a curve?

The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels.

How do you find the power of torque?

Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.

Which gives the power of a torque?

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. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

What is the relation between torque and power?

Torque is the rotational equivalence of linear force. Power is work done in a time interval. The relation between torque and power is directly proportional to each other. The power of a rotating object can be mathematically written as the scalar product of torque and angular velocity.

What is the relation between torque and speed?

Torque is inversely proportional to speed. Thus, when speed increases, torque will decrease.

What do full load torque and power curves show?

Full load torque and power curves highlight the maximum torque and power distribution through the whole range of engine speed. The shape of the above torque and power curves are not from a real engine, the scope being to explain the main parameters.

What kind of torque curve does a street car have?

For a street car, the engine has a relatively flat torque curve (compared to race car engines, which tend to have “peaky” torque curves with the peak at high rpm for maximum power).

How to calculate the torque of an engine?

You can measure torque and RPM and you have to calculate the Horsepower (HP) from them and not vice versa. A typical engine performance curve is shown below: Torque curve (shown in Dark red color) is the graph plotted between torque and RPM of the engine.

What happens to the torque curve as RPM increases?

Torque curve (shown in Dark red color) is the graph plotted between torque and RPM of the engine. Normally it also plotted along with the HP curve of the engine (shown in green). You must observe that as the RPM increases, both the curve become steeper. This is because, as the RPM increases the cylinder pushes more…

How do you calculate electric motor torque?

How to Calculate Electric Motor Torque. Watts = volts * amps. 1HP (horsepower) = 746 watts. Torque (T) = ((HP(horsepower) / RPM (rotations per minute))) * 63,025 (constant) 1. Find the wattage from a motor that has the following nameplate data on its metal tag; 120 Volts at 10 amperes with a 3600-RPM.

What is power vs torque?

The one of the major difference between power and torque is that the power is the amount of work done by an object whereas the torque is the tendency of the force to rotate the object in a particular direction.

What is the relationship between speed and torque?

In Classical Mechanics, speed and torque have an inverse (or opposite) relationship – as one increases the other decreases. Higher speed means lower torque, and higher torque means lower speed. Also, the amount of power supplied has an effect on how much speed and/or torque can be produced in a mechanical system.

What is a motor speed torque curve?

A speed-torque curve is a plot graphing the relationship between the speed, often measured in revolutions per minute or RPM, and the torque produced by a motor (electric, internal combustion, or other types). The “speed” aspect is often implied, and it will simply be called a “torque curve”.
