## Motor Power Formula

The following formula is used to calculate the Motor Power.

**P = t * 2*PI*RPM/60**

- Where P is the Motor Power (watts)
- t is the motor torque (N-m)
- RPM is the angular speed (RPM)

## How to Calculate Motor Power?

The following two example problems outline how to calculate the Motor Power.

**Example Problem #1:**

- First, determine the motor torque (N-m). In this example, the motor torque (N-m) is measured to be 36.
- Next, determine the angular speed (RPM). For this problem, the angular speed (RPM) is calculated to be 72.
- Finally, calculate the Motor Power using the formula above:

P = t * 2*PI*RPM/60

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

P = 36 * 2*3.14159*72/60 = 271.433 (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:

motor torque (N-m) = 10

angular speed (RPM) = 9

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

P = 10 * 2*3.14159*9/60 = 9.424 (watts)
