# How do you calculate torque from RPM?

## How do you calculate torque from RPM?

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

How do you calculate gear torque?

Divide the diameter of the output gear by the diameter of the input gear. Multiply the torque of the motor by the gear ratio to get the output torque. For example, a motor that puts out 10 lb. -feet of torque used with a gear reducer with a 10:1 gear ratio will give you 100 lb.

What is torque feet?

The unit of measure for torque that we all know, the “ft-lb,” “lb-ft,” or “foot-pound” is the amount of turning force applied to move one pound a distance of one foot around an axis at a radius of one foot.

### What is torque RPM?

RPM- Stands for rotations/revolutions per minute. This is a measurement of how fast your engine is rotating. Torque- Torque is a measurement of rotational force. The more torque a car has the faster it accelerates, the more horse power a car has, the higher its top speed will be.

How do you calculate RPM from torque without power?

1. Suppose we take two most common equations for Horsepower:
2. HP = Torque (lb-ft) x rpm / 5252.1131.
3. HP = Cylinder Pressure (psi) x Displacement (cubic inches) x efficiency x rpm/ 792,000.
4. Combining then Torque x rpm /5252.1131 = Pressure x Disp x Eff x rpm / 792000.

How do I calculate RPM?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

## How do you calculate watts from RPM and torque?

Calculate the motor power rating in watts of the ac motor which has rated torque of 144Nm at 1480 rpm. Apply our torque to watt conversion formula, Motor power in watt = 0.105 * 144 * 1480 = 22306 Watts.

What is lbf ft stand for?

A pound-foot (lbf⋅ft) is a unit of torque representing one pound of force acting at a perpendicular distance of one foot from a pivot point. Conversely one pound-foot is the moment about an axis that applies one pound-force at a radius of one foot. One pound (force) = 4.448 222 newtons.

Is torque same as RPM?

RPM- Stands for rotations/revolutions per minute. This is a measurement of how fast your engine is rotating. Torque- Torque is a measurement of rotational force. Torque is applied to your wheels which makes them rotate.

### How do you calculate horsepower from torque in rpm?

HP = T × S T Only after these three items have been determined is it = Torque in lb. ft. 5252 S = possible to calculate the required horsepower for the appliSpeed in RPM OR HP = T × S T = Torque in lb. in. 63,025 S = Speed in RPM OR HP = T × S T = Torque in in. ounces 1,000,000 S = Speed in RPM

How to calculate motor power from gearbox torque?

Know Torque on gearbox output shaft/bore, the output speed of gearbox and service factor, how to calculate motor power? Motor Power(HP/Kw)=Torque (N.m) /9550×Input Speed of motor Power(Kw) / Ratio / Service factor. The industrial gearbox is a precision machine relatively, it’s purpose is to decrease motor speed, increased output torque.

What is the formula for torque?

t = WR 2× N 308T T= Average accelerating torque in lb. Ft. N = Required change in speed WR2= Inertia in lb. ft.2 t = Time in seconds The same formula can be rearranged to determine the av- erage accelerating torque required to produce full speed in a given period of time. T = WR 2× N 308t

## How to calculate gear reducer torque?

Gear Reducer Torque = 9550 * Motor power / Rated Power motor’s input revolution*Ratio* gear reducer efficiency. The above calculation is the torque equation. Motor power = torque ÷ 9550 × Rated power‘s motor input speed /Ratio /service factor. Here useful converted relationship to Output torque’s unit :
