How is power and torque related?
Back to Berra’s theorem, torque is the capacity to do work, while power is how quickly some strenuous task can be accomplished. 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.
How do you convert torque to watts?
Watt (W) to Torque (Nm) Calculation: Motor Torque T(Nm) in Newton meter (Nm) is equal to 9.554140127times of the electric power P(W) in watts divided by the speed N(rpm) in rpm. Example: Calculate the rated torque can be developed by the 22000 Watts, 1490 rpm three-phase motor. T(Nm) = 144 Nm.
How do you convert torque to power?
HP = Torque x RPM ÷ 5252 An engine produces POWER by providing a ROTATING SHAFT which can exert a given amount of TORQUE on a load at a given RPM.
How do you calculate the power of a motor?
Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.
What is PS and Nm in car?
NM – Newton metres is the unit to measure the torque. PS – It is a unit used to measure the power output of the engine. In simple words it’s called Horse power. 1 Reply.
What horsepower is 5252?
One horsepower is equal to 33,000 foot-pounds of work per minute. Add in the equations relating to torque and velocity, and you’ll find that horsepower always equals torque multiplied by rpm, divided by 5,252. Canceling out the equal variables, you wind up with horsepower equaling torque… at 5,252 rpm.
How do you convert force to power?
In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv.
How is torque equation derived?
By definition, torque τ = r × F. Therefore, torque on a particle is equal to the first derivative of its angular momentum with respect to time.
