Stepper Motor Torque Formula
The following formula is used to calculate the Stepper Motor Torque.
Tsm = KT*i
- Where Tsm is the Stepper Motor Torque (N-m)
- KT is the motor torque constant (N-m/amp)
- i is the total current (amps)
How to Calculate Stepper Motor Torque?
The following two example problems outline how to calculate the Stepper Motor Torque.
Example Problem #1:
- First, determine the motor torque constant (N-m/amp). In this example, the motor torque constant (N-m/amp) is measured to be 40.
- Next, determine the total current (amps). For this problem, the total current (amps) is calculated to be 100.
- Finally, calculate the Stepper Motor Torque using the formula above:
Tsm = KT*i
Inserting the values from above and solving the equation with the imputed values gives:
Tsm = 40*100 = 4000 (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:
motor torque constant (N-m/amp) = 30
total current (amps) = 20
Entering these values yields:
Tsm = 30*20 = 600 (N-m)
