Enter the total engine power (watts) and the total run time of engine (s) into the calculator to determine the Motor Energy.

## Motor Energy Formula

The following equation is used to calculate the Motor Energy.

Em = MP * T

Variables:

• Where Em is the Motor Energy (Joules)
• MP is the total engine power (watts)
• T is the total run time of engine (s)

## How to Calculate Motor Energy?

The following two example problems outline the steps and information needed in order to calculate the Motor Energy.

Example Problem #1:

1. First, determine the total engine power (watts). In this example, the total engine power (watts) is measured to be 58.
2. Next, determine the total run time of engine (s). For this problem, the total run time of engine (s) is calculated to be 4.
3. Finally, calculate the Motor Energy using the formula above:

Em = MP * T

Inserting the values from above and solving the equation with the imputed values gives:

Em = 58 * 4 = 232 (Joules)

Example Problem #2:

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

total engine power (watts) = 49

total run time of engine (s) = 10

Entering these values into the formula or calculator above gives us:

Em = 49 * 10 = 490 (Joules)
