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
- First, determine the total kilovolts (kV). In this example, the total kilovolts (kV) is given as 5 .
- Next, determine the current (amps). For this problem, the current (amps) is given as 13 .
- Next, determine the rotational speed (RPM). In this case, the rotational speed (RPM) is found to be 5.
- 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)
