Stall Torque Formula
The following formula is used to calculate the Stall Torque.
Tstall = Is * K
- Where Tstall is the Stall Torque (N-m)
- Is is the stall current (amps)
- K is the motor’s torque constant (N-m/amp)
How to Calculate Stall Torque?
The following two example problems outline how to calculate the Stall Torque.
Example Problem #1:
- First, determine the stall current (amps). In this example, the stall current (amps) is measured to be 120.
- Next, determine the motor’s torque constant (N-m/amp). For this problem, the motor’s torque constant (N-m/amp) is calculated to be 50.
- Finally, calculate the Stall Torque using the formula above:
Tstall = Is * K
Inserting the values from above and solving the equation with the imputed values gives:
Tstall = 120*50 = 6,000 (N-m)
Example Problem #2:
Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:
stall current (amps) = 60
motor’s torque constant (N-m/amp) = 20
Entering these values yields:
Tstall = 60 * 20 = 1200 (N-m)
