Stepper Motor Voltage Formula
The following formula is used to calculate the Stepper Motor Voltage.
Vsm = Ism * PR
Variables:
- Where Vsm is the Stepper Motor Voltage (volts)
- Ism is the stepper motor current (amps)
- PR is the phase resistance (ohms)
How to Calculate Stepper Motor Voltage?
The following two example problems outline how to calculate the Stepper Motor Voltage.
Example Problem #1:
- First, determine the stepper motor current (amps). In this example, the stepper motor current (amps) is measured to be 16.
- Next, determine the phase resistance (ohms). For this problem, the phase resistance (ohms) is calculated to be 8.
- Finally, calculate the Stepper Motor Voltage using the formula above:
Vsm = Ism * PR
Inserting the values from above and solving the equation with the imputed values gives:
Vsm = 16 * 8 = 128 (volts)
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:
stepper motor current (amps) = 71
phase resistance (ohms) = 81
Entering these values into the formula or calculator above gives us::
Vsm = 71 * 81 = 5751 (volts)
