AC Motor Torque Formula
The following formula is used to calculate the AC Motor Torque.
Tac = 9.5488 * ACP /S
- Where Tac is the AC Motor Torque (N-m)
- ACP is the AC motor power (kW)
- S is the speed (RPM)
How to Calculate AC Motor Torque?
The following two example problems outline how to calculate the AC Motor Torque.
Example Problem #1:
- First, determine the AC motor power (kW). In this example, the AC motor power (kW) is given as 15.
- Next, determine the speed (RPM). For this problem, the speed (RPM) is given as 40.
- Finally, calculate the AC Motor Torque using the equation above:
Tac = 9.5488 * ACP /S
Inserting the values from above and solving the equation with the imputed values gives:
Tac = 9.5488 * 15 /40 = 3.5808 (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:
AC motor power (kW) = 41
speed (RPM) = 100
Entering these values yields:
Tac = 9.5488 * ACP /S = 3.91508 (N-m)
