Enter the rated power (kW) and the rated speed (rpm) into the calculator to determine the Induction Motor Torque.

## Induction Motor Torque Formula

The following formula is used to calculate the Induction Motor Torque.

Tim = 9550-rP*rS
• Where Tim is the Induction Motor Torque (N-m)
• rP is the rated power (kW)
• rs is the rated speed (rpm)

To calculate the induction motor torque, subtract the product of the rated power and speed from 9550.

## How to Calculate Induction Motor Torque?

The following two example problems outline how to calculate the Induction Motor Torque.

Example Problem #1:

1. First, determine the rated power (kW). In this example, the rated power (kW) is given as 43.
2. Next, determine the rated speed (rpm). For this problem, the rated speed (rpm) is given as 72.
3. Finally, calculate the Induction Motor Torque using the equation above:

Tim = 9550-rP*rS

Inserting the values from above and solving the equation with the imputed values gives:

Tim = 9550-43*72 = 6454 (N-m)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are:

rated power (kW) = 95

rated speed (rpm) = 12

Entering these values yields:

Tim = 9550-95*12 = 8410 (N-m)
