Enter the total kilovolts (kV), the current (amps), and the rotational speed (RPM) into the calculator to determine the Torque from kV.

## Torque from kV Formula

The following formula is used to calculate the Torque from kV.

Tkv = kV*1000*I/(2*pi*RPM)

• Where Tkv is the Torque from kV (N-m)
• kV is the total kilovolts (kV)
• I is the current (amps)
• RPM is the rotational speed (RPM)

## How to Calculate Torque from kV?

The following example problems outline how to calculate the Torque from kV.

Example Problem #1

1. First, determine the total kilovolts (kV). In this example, the total kilovolts (kV) is given as 5 .
2. Next, determine the current (amps). For this problem, the current (amps) is given as  13 .
3. Next, determine the rotational speed (RPM). In this case, the rotational speed (RPM) is found to be 5.
4. Finally, calculate the Torque from kV using the formula above:

Tkv = kV*1000*I/(2*pi*RPM)

Inserting the values from above and solving yields:

Tkv = 5*1000*13/(2*3.1415*5) = 2069.07 (N-m)

Example Problem #2

Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:

total kilovolts (kV) = 7

current (amps) = 9

rotational speed (RPM) = 7

Enter these given values yields:

Tkv = 7*1000*9/(2*3.14159*7) = 1432.39 (N-m)
