Induction Motor Torque Calculator

Formula

To calculate the Induction Motor Torque:

\[ Tim = 9550 - (rP \times rS) \]

Where:

\(Tim\) is the Induction Motor Torque (N-m)
\(rP\) is the rated power (kW)
\(rS\) is the rated speed (rpm)

What is Induction Motor Torque?

Induction motor torque is the rotational force produced by an induction motor. It is a crucial parameter in determining the motor's performance and efficiency. The torque is influenced by the motor's power and speed, and understanding it is essential for designing and operating electric motors in various applications.

Example Calculation 1

Let's assume the following values:

Rated Power (\(rP\)) = 10 kW
Rated Speed (\(rS\)) = 1500 rpm

Using the formula:

Step 1: Multiply the rated power by the rated speed:

\[ rP \times rS = 10 \times 1500 = 15000 \]

Step 2: Subtract the result from 9550:

\[ Tim = 9550 - 15000 = -5450 \]

The induction motor torque is -5450 N-m.

Example Calculation 2

Let's assume the following values:

Rated Power (\(rP\)) = 5 kW
Rated Speed (\(rS\)) = 1000 rpm

Using the formula:

Step 1: Multiply the rated power by the rated speed:

\[ rP \times rS = 5 \times 1000 = 5000 \]

Step 2: Subtract the result from 9550:

\[ Tim = 9550 - 5000 = 4550 \]

The induction motor torque is 4550 N-m.
