Voltage from RPM Formula
The following formula is used to calculate the Voltage from RPM.
V = 2*pi / 60 * t * w / I
- Where V is the Voltage from RPM (volts)
- t is the torque (N-m)
- w is the RPM
- I is the current (amps)
To calculate the voltage from RPM, multiply the torque by the RPM, divide by the current, then multiply by 2 times pi over 60.
How to Calculate Voltage from RPM?
The following example problems outline how to calculate Voltage from RPM.
Example Problem #1
- First, determine the torque (N-m). In this example, the torque (N-m) is determined to be 15 .
- Next, determine the RPM. For this problem, the RPM is measured to be 4 .
- Next, determine the current (amps). In this case, the current (amps) is found to be 50.
- Finally, calculate the Voltage from RPM using the formula above:
V = 2*pi / 60 * t * w / I
Inserting the values from above and solving yields:
V = 2*3.14159/ 60 * 15 * 4 / 50 = .125 (volts)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
torque (N-m) = 41
RPM = 1
current (amps) = 52
Enter these given values into the calculator or above yields:
V = 2*3.1415/ 60 * 41 * 1 / 52 = .082 (volts)
