## No Load Current Formula

The following formula is used to calculate the No Load Current.

In-L = FLC * R/100

- Where In-L is the No Load Current (amps)
- FLC is the full load current (amps)
- R is the percentage of full load current (%)
- star motor = 10%
- delta motor = 30%
- dc motor = 25%

To calculate the no-load current, multiply the full load current by the percentage load factor over 100.

## How to Calculate No Load Current?

The following two example problems outline how to calculate the No Load Current.

**Example Problem #1:**

- First, determine the full load current (amps). In this example, the full load current (amps) is measured to be 450.
- Next, determine the percentage of full load current (%). For this problem, the percentage of full load current (%) is calculated to be 52.
- Finally, calculate the No Load Current using the formula above:

In-L = FLC * R/100

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

In-L =450* 52/100 = 234 (amps)

**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:

full load current (amps) = 120

percentage of full load current (%) = 42

Entering these values into the formula above gives :

In-L = 120* 42/100 = 50.4 (amps)
