Anyone knows the torque structure ?relation between the speed and torque?

@Reya • 25 Dec, 2011
Torque and speed are inversely proportional. why did you give 5 and 3 as options? what does it mean?

Torque can be increased at the cost of speed.

at a constant power output torque is inversely to speed. i

*f power is increasing torque or speed or both can increase significantly.*

For any rotating machine:

Torque is propotional to the power but,

If you need more information with regard to application please say.

at constant power ,speed is inversly propo to torque.. P=2*pi*N*T/60..

@antuan.o • 20 Jan, 2012
So torque is inversly to speed? Could you explain your formula please. Why /60 ?

@N.Gowtham Raj • 26 Jan, 2012
/60 is for N.....

N is revolutions per minute

But T is in seconds

So , we convert rpm(revolutions per minute) in to rps(revolutions per second) dividing it by 60...

Torque is the load carrying capacity in crude words...

More over the best example for demonstrating the difference is

1. BENZ car- High speed, Less torque(Load carrying capacity- 4+1 people)

2. BUS - Low speed , High Torque(High load carrying capacity-55 + 2 people)

Power[kw]

={torque[N-m]*pi*rotational speed in RPM }/30000

Power[kw]*30000

=torque[N-m]*pi*rotational speed in RPM

TORQUE

={Power[kw]*30000}/pi*rotational speed in RPM

From the above formula,it is clear that torque decreases with speed in Torque vs speed curves.

in even more simple words,

thus greater the diameter of the wheel , the lesser the force that can be applied.

and thus when the diameter of the wheel increases its speed decreases

hence torque and speed are inversely proportional

**speed :**it is merely the number of rotations of a wheel or gear per second or per minute or per unit time.**torque :**it is the leverage applied to rotate a circular machine member . it is the product of the force applied on a wheel to rotate it and the diameter of the wheel.thus greater the diameter of the wheel , the lesser the force that can be applied.

and thus when the diameter of the wheel increases its speed decreases

hence torque and speed are inversely proportional

@Ravinder jamwal • 07 Jul, 2015
i think increase in torque also increase speed
