Enter the output power (watts) and the efficiency (%) into the calculator to determine the Brushless Motor Input Power.
Brushless Motor Input Power Formula
The following formula is used to calculate the Brushless Motor Input Power.
Pi = Po/(E/100)
- Where Pi is the Brushless Motor Input Power (watts)
- Po is the output power (watts)
- E is the efficiency (%)
How to Calculate Brushless Motor Input Power?
The following two example problems outline how to calculate the Brushless Motor Input Power.
Example Problem #1:
- First, determine the output power (watts). In this example, the output power (watts) is measured to be 50.
- Next, determine the efficiency (%). For this problem, the efficiency (%) is calculated to be 50.
- Finally, calculate the Brushless Motor Input Power using the formula above:
Pi = Po/(E/100)
Inserting the values from above and solving the equation with the imputed values gives:
Pi = 50/(50/100) = 100 (watts)
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:
output power (watts) = 40
efficiency (%) = 30
Entering these values into the formula or calculator above gives us::
Pi = 40/(30/100) = 133.33(watts)
